World IPv6 Day figures from Google indicate success

Google, Facebook promise new IPv6 services after successful trial

Google said it has decided to leave its main YouTube website enabled for IPv6 for the time being. Since 2008, Google has supported IPv6 on separate websites -- such as www.ipv6.google.com -- rather than on its main websites.

"We saw 65% growth in our IPv6 traffic on World IPv6 Day," said Lorenzo Colitti, IPv6 Software Engineer at Google, who pointed out that Google added IPv6 support to several new services including Orkut for the trial. "This event has really been successful in galvanizing the community."

World IPv6 Day today

WORLD IPV6 DAY is 8 June 2011 – The Future is Forever

Today is World IPv6 Day, organised by the Internet Society (ISOC). Internet Society - World IPv6 Day.

Read the "About IPv6" section of the Irish IPv6 Task Force website if this means nothing to you :-)

Many people are experimenting with turning on IPv6 for the first time, and/or turning off IPv4 to see if the IPv6 infrastructure can cope.

So today is a good day to test your own machine to see how well it can cope with the next generation internet protocol, IPv6: http://www.testipv6.com.

In Ireland there is a good IPv6 readiness site, http://www.ipv6ready.ie, sponsored by the INEX, the Dublin Internet Neutral Exchange.

The Irish IPv6 Task Force has also a website for the day, http://www.ipv6day.ie, the site includes a monitoring tooolset that monitors IPv6 readiness for high profile public and private sector Irish internet sites.

Nortel, in bankruptcy, sells IPv4 address block for $7.5 million

IGP Blog :: Nortel, in bankruptcy, sells IPv4 address block for $7.5 million. The RIRs have long argued that they assign the IP addresses, and that they are not owned, so I am not sure that this will stand up in the end, but the claim is that Nortel have sold an IPv4 allocation to Microsoft as part of their bankruptcy process.

Irish IPv6 Task Force Press Release

The IPv6 Forum Worldwide Chapters' Leaders & Experts call for Swifter Move to IPv6

For Internet Sustained growth and Future Innovation

WATERFORD, IRELAND 4th February 2011.

“The Irish IPv6 Task Force joins its affiliate organisations in the IPv6 Forum to call on the ICT industry to respond to the networking needs of the future. Our contribution towards the required migration to IPv6 is the set of online resources we have created, including two sets of videos of summits that provide detailed advice background context, see http://www.ipv6.ie/” says Dr Mícheál Ó Foghlú, Chair Irish IPv6 Task Force and Executive Director Research TSSG, Waterford IT.

The IANA (Internet Assigned Numbers Authority- www.iana.org ) has allocated the last IP address blocks from the global IPv4 central address pool, ending all debates over when this would happen. Several months remain before Regional Registries consume all their remaining regional IPv4 address pools, with recent trends suggesting that Asia, Europe, and North America will exhaust in that order within a month or two on either side of July 1, 2011.

“The Internet has become the global communication network, now is the time to sustain its growth and stability by integrating IPv6. IPv6 adds great value to IPv4” states Dr. Vint Cerf, Honorary Chair, IPv6 Forum.

“The Internet is for Everyone. IPv6 represents the next stage of the Internet's evolution and will help make this vision a reality,” states Lynn St. Amour, President & CEO, Internet Society.

The eventuality of this day was foreseen by the IETF almost 20 years ago, and a replacement was developed. In 1999 the IPv6 Forum was established by the IETF IPv6 Task Force with the mission to educate and promote the new protocol, and now that we have reached the end of the IPv4 free pool, that mission is more urgent than ever. The IPv4 based Internet will not stop working, but it will stop growing, while the IPv6 based Internet is designed to grow for generations to come.

In our daily lives, failure of the Internet infrastructure or restrictions on its capabilities to add new users or support the worldwide economy are no longer acceptable. Therefore, the IPv6 Forum recommends to all people involved in ICT, that now is the time to leverage 2011 and 2012 for planning and rolling out the new version of the Internet Protocol. Enabling IPv6 in all ICT environment is not the end game but is now a critical requirement for continuity in all Internet business and services going forward. Production quality deployments will take time, Starting late and accelerating the process will compromise quality and significantly raise the costs. The last thing that everyone should avoid is to have to rapidly deploy an unnecessarily costly IPv6 infrastructure to sustain growth and communicate with customers, suppliers, and partners.

Transition planning and adoption of IPv6 is now critical to the on-going stability and growth of Internet Protocol based ICT, not only in the public Internet but in every facet of your office, home and mobile electronic existence where TCP/IP and other IP protocols are used. Training, management, support, billing, security and applications development need to be engaged to allow you to be IPv6 ready.

This call is more critical to developing nations that strive to modernize their critical Internet infrastructure making it future proof and protecting their investments.

“The time is now! And resistance is futile,” states Latif Ladid, IPv6 Forum President Senior Researcher at University of Luxembourg, Security and Trust (SnT) Center. Emeritus Trustee, Internet Society.

“Attempting to predict this date has been an interesting challenge over the years, given the chaotic nature of global Internet growth. The challenge ahead for the larger community will be to move past denial, mourning, and grief, and get on with the task of IPv6 deployment,” states Tony Hain, IPv6 Forum Fellow, Technical Director, North American IPv6 Task Force.

“If you think you can ignore IPv6, think again. As new IPv4 addresses cannot be acquired the industry will be faced with customers / partners / suppliers who can only be reached via IPv6. Our industry will need to face the “balkanization” of the Internet. It is time to act and to deploy IPv6 now,” states Yanick Pouffary, NAv6TF Technology Director, IPv6 Forum Fellow and IPv6 Forum (Ready & Enabled) Logo Programs Chairperson.

Excellent Netscape documentary from 1998-99

I just read an interesting blog post from Jeff Atwood Coding Horror: Lived Fast, Died Young, Left a Tired Corpse (thanks to @rjroger)

The post has links to the documentary film of Netscape pushing to release open source with a tight deadline: Code Rush. For a very long time, Code Rush was almost impossible to find, but the activism of Andy Baio nudged the director to make the film available under Creative Commons.

It is salutary to see the development environment that drove one of the lasting legacies of the original dot com bubble, I am typing this in a Firefox (Mozilla) browser window using a MovableType Perl backend CMS, all technologies of that era, the open source Firefox being the direct legacy of Netscape. I am CTO of FeedHenry, a company that is basing its mobile app strategy on JavaScript, another legacy of that era. What comes around goes around.

World IPv4 Stocks Finally Run Out

IANA, the Internet authority, has assigned its last batches of IPv4 addresses to the RIRs (Regional Internet Registries), putting pressure on companies to adopt IPv6. See the Irish IPv6 Task Force for more information, particularly the last two Irish IPv6 Summits in 2010 and 2009, lots of good slides and videos on-line.

Geoff Huston's prediction model now cites only the next projected deadline, when RIR's allocation will run out. His prediction model for the IANA /8 pool, that I have been tracking since 2005, has now reached its reality checkpoint: 1st Feb 2011.

So in a very real way today marks the beginning of the end of the Internet as we know it. This morning, the Internet authority IANA allocated two batches of IPv4 addresses to APNIC, the regional Internet registry of the Asia Pacific, leaving just five batches (known as /8s) in the global pool.

Some time ago, the Regional Internet Registries (RIRs) agreed that, when IANA got down to the last five /8s, IANA would allocate them automatically to the five RIRs, regardless of whether or not those registries needed more IP addresses at the time. That day has arrived, meaning that IANA’s stock of IPv4 addresses is now fully depleted.

I am tempted to say "The end of the world is neigh!" but in fact things will continue much as normal for some time. The point is that when the RIRs run out, that's it, no more IPv4 (or very expensive recycled IPv4). So we have probably less than one year to migrate to IPv6, if want the Internet to continue to be able to grow. Of course this is not feasible, so we are now pretty much guaranteed a messy overlap period of a fully allocated IPv4 Internet that cannot grow any further co-existing with a fresh new IPv6 world that has not yet grown to be the same size, but will do so over time (years? decades?). I really hope we can push people to migrate quickly, as I like the idea of an Internet that can grow, and I hope you do too.

Please Act Now!

Update 2011-02-03

And I'm quoted here: Silicon Rebublic, Internet to run out of available IP addresses tomorrow (based on what was said at the previous Irish IPv6 Summit in May 2010).

Daniel Karrenberg's facinating article in similarities between Internet industry and Financial industry

graphic comparing Internet and Financial industries

The ISP Industry and the Financial Sector - Amazing Similarities

A really interesting article, as you can see from the diagram.

In the last RIPE Labs article on this subject How Does the Internet Industry Compare?, we looked at ways to compare our industry with other industrial sectors, and identified a number of characteristics that an industry must have in order to be comparable to the Internet industry. It seems the financial sector or monetary credit industry shares many of these characteristics and in fact behaves much like the Internet industry.

The three main factors that determine the cumulative distribution of resources in both industries are:

  • centrally administered coordination policies

  • commercial strategies and competition between each industry members determines how fast each of them grows

  • the absolute size of the user base and the varying demands of individual users.

Science Spin Interview on IPv6

Sean Duke interviewed with me recently about IPv6 and the Future Internet. This interview was broadcast on Science Spin on Dublin's Spin FM (103.2) on the 17th June, 2010. Sean was kind enough to give longer than the traditional two minute "sound bite", instead this is a ten minute discussion that allows time for a bit more depth.

You can listen to podcast of this interview, after the introductions mine is the first segment (time 00:50 to 11:10).

TSSG wins first place in Ericsson Mobile Application Awards


I am very happy to announce that a team of programmers from the TSSG have won first place in the Ericsson Mobile Application Awards. The global student competition generated over 700 registered users, 120 registered teams from 28 countries worldwide and the involvement of 1000 end-users globally. The jury selected the winners yesterday at the Nordic Mobile Developer Summit in Stockholm.

Pictured above is Robert Mullins and the two part-time students Kieran Ryan and Mark Williamson who are both members of the TSSG and students on the TSSG-sponsored MSc Communications Software in Waterford Institute of Technology.

The winning entry has an associated YouTube video and was based on the development of a "Caller Profiler application".

This success demonstrates the capability within the TSSG to translate from a high level research interest in telecommunications networks and services, through to real software development that can have an impact on industry, with a link back to WIT's teaching curriculum, in particular with specialised targeted MSc (taught) course offerings designed to enable professional development of specialist software skills.

Robert Mullins led the TSSG's engagement in Enterprise Ireland funded ILRP IMS-ARCS project that built enablers for next generation IMS services. The development work for the competition was enabled by Enterprise Ireland funding linked to one of the IMS-ARCS industrial members Vennetics as partner.

We are grateful to Ericsson for the opportunity to take part in this competition. Ericsson, both in Ireland and in Sweden, work closely with the TSSG in supporting our Next Generation Network TSSG Centre (funded by the TSSG, Enterprise Ireland, and Science Foundation Ireland), and have worked with us on many leading edge research projects.

Well done to the winning team!

Patsy Phelan at FutureNet 2010

It is great to see the TSSG pushing some of its ideas at big events. Here we are helping re-think the Internet from scratch, by allowing experimentation immediately with any new form of networking protocol, directly programmed in Java. Patsy Phelan, one of our researchers who has been working on the EU FP7 project 4WARD, has been promoting the flexible software he has developed that allows us to deploy new or tweaked networking protocols, at any OSI layer, coded directly in Java. The platform will be released under an open source licence in the near future.

Welcome to FutureNet 2010. For over 10 years FutureNet has been the must attend event for service providers, IT managers, and consultants to stay ahead of the rapidly changing communications services market. This year is no different as we'll address the sustainability of the Internet for business, look at emerging trends around Ethernet, wireless, and SIP, and help you put together a "Green" strategy by evaluating new service options. We'll also examine the management and support strategies necessary to achieve success. We look forward to seeing you this year at FutureNet 2010 in Boston!

    IMS-ARCS @ Digital Hub - Stakeholder Meeting

    IMS-ARCS @ Digital Hub - Stakeholder Meeting
    Originally uploaded by mofoghlu
    This morning I attended the stakeholder meeting of IMS ARCS (http://www.ims-arcs.org) project.

    This is an interesting project partly because of the funding mechanism. It is an Enterprise Ireland ILRP, Industry-Led Research Programme. These programmes are defined by a group of industrial partners, who then use Enterprise Ireland funding to fund the research activity in Higher Education Institutions in Ireland. This can be seen as the Irish equivalent (on a smaller scale) of the EU Technology Platforms (EUTPs http://cordis.europa.eu/technology-platforms/).

    The project is also interesting as it tracks a major trend in telecommunications: the emergence of the IMS platform (IP Multimedia Subsystem) and the dominant paradigm for fixed-mobile convergence, and for the migration of telecommunications networks to the use of Internet protocols.

    The TSSG has used its existing expertise, and the new expertise and market intelligence gathered during this, and other projects, to help create a national IMS testbed. We will be launching this testbed formally early next year.

    Smartphone Battles


    It is fascinating how in a short space of time the Android platform is emerging as a major challenger to the iPhone in the smartphone market, and also indeed how quickly the iPhone itself became a dominant player in this market. This ZDNET article by Jason Perlow neatly sums up these trends, if slightly provocatively. A good starting point for debate on the future handsets, which is also a big part of the future of the Internet.

    A Revolution 40 Years in the Making

    Computing Now | A Revolution 40 Years in the Making

    The IEEE Computer Society have publsihed this interesting retrospective to mark 40 years of the Internet. It's a summary page, with links to two articles: An interview with Len Kleinrock on the origins of the Internet (Mar/Apr 1997 IEEE Internet Computing); A contribution on the Internet's future (Jan/Feb 2000).

    I think a lot of people who talk about the Future Internet should read this and understand what the Internet is and where it came from, so that their ideas on possible future directsions are grounded in the reality of what actually happened so far.

    Of course, I'm having such conversations, and many otehr stimulating conversations, as I am in Istanbul for the eChallenges 2009 conference.

    GoMo News: Not legal to unlock iPhones in USA and Ireland, but it is in other countries such as Finland

    Cian O'Sullivan of GoMo News (a TSSG spin-in company) reports that Legal unlock for iPhone shows just how bad USA and Ireland have got it. I had never realised this - the extent to which the legal unlocking of phones was dictated by one's country, but it does make sense.

    As it happens, I use a Sony Ericsson P1i, that is unlocked, a bit of a last year's smart phone but I still like it a lot. I must admit it isn't as good at email as a Blackberry, and it isn't as good at web browsing as an iPhone, but it suits me grand for now.

    EU backs proposal by ComReg to reduce Eircom access charges


    Continuing on an Irish broadband theme, this article in Silicon republic has some interesting statistics, that Eircom provides, directly or indirectly, 96pc of the country's broadband (I assume this statistic excludes mobile broadband):

    Silicon Republic article: EU backs ComReg proposal to cut Eircom access charges

    As a result of the EU decision, Eircom will have to reduce the fee it charges other operators to access the ‘last mile’ of its infrastructure to provide broadband internet services to homes and businesses.

    At present, 96pc of all DSL broadband sold in Ireland is sold either as an Eircom product or is re-sold by other operators.

    EU Competition Commissioner Neelie Kroes said: “ComReg's proposal is good news for competition and consumers. Alternative operators will have to pay considerably less for access to Eircom's broadband network. They will thus be in a position to make more attractive retail offers and consumers will get a better choice.”

    3 upgrade Irish mobile data infrastructure with NSN equipment


    3 and Nokia Siemens Networks complete radio technology upgrade and demonstrate Ireland’s first roll out of I-HSPA

    It is nice to see investment in faster mobile broadband being rolled out in Ireland. This is a direct result of the government's (DCENR rural broadband scheme) choice to contract out rural broadband to mobile, and this decision has already had some positive benefit. Hopefully the other mobile operators will follow suit. Hopefully as well it will not lead to the stagnation of fixed broadband, that currently can offer better performance when the infrastructure is there to support it.

    Nokia Siemens Networks' I-HSPA (Internet High-Speed Packet Access) technology is currently being rolled out as part of the National Broadband Scheme, and will be extended to 3's existing network in Ireland. It is the first commercial deployment of I-HSPA in Ireland.

    GlowCaps CONNECT: network enabled pill boxes!


    This is a good example of how we are indeed moving towards an "Internet of Things" where everyday items become network enabled, and new services are built to explicit this new communications ability.

    Vitality - GlowCaps Connect

    The idea is that a patient who has to take regular medication can use these networked enabled pill box lids to help them track that they have taken their medication on schedule. The devices come with a warning lamp that can be plugged into any electrical socket in the house; this device communicates back to the pill box and glows a warning colour when it is time to take medications. The system can also dispatch weekly emails to a supportive family member. It seems that it being marketed as an integrated service where the end user rings a phone number to setup his required schedule. The information is also passed on to the doctor, so the patient is more accountable.

    • Personal Reminders GlowCaps flash and play a melody so you don’t forget. They can even call your home phone to remind you (optional).

    • Social Network Support: Send a weekly update to a friend, family member or caregiver (optional).

    • Refill Coordination: GlowCaps count your pills and remind you to order refills from your pharmacy before you run out.

    • Doctor Accountability: Each month, GlowCaps mail you and your doctor a report with incentives if you exceed your adherence goal

    The Great GoogleLapse

    The Great GoogleLapse: Security to the Core | Arbor Networks Security This post has an excellent graph of the recent network outage caused by a routing error for some users of Google services. One explanation I read has linked this to an IPv6 upgrade in Google. This is an interesting event for a number of reasons:
    • It reminds us that even the best managed Internet services can have problems, and that there is a serious risk in trusting your IT requirements to external services on the network. This is wake up call for those overly enthusiastic about cloud computing in particular and software services in general.
    • Despite this, the outage was relative short, less than two hours, which is a lot better than the speed with which my own organisation could expect to solve a technical problem. But then we don't have the same requirements as many large enterprises would.
    • It is interesting that IPv6 was one of the culprits. It is often blamed for network problems at present, partly because peope don't know enough to rule it out, and partly because it does sometimes lead to some strange problems (c.f. Geoff Huston's blog post of web client issues linked to IPv6 for an example of some real issues with IPv6).

    IPv6 and the Internet of Things

    Whilst representing Ireland at the EU IPv6 Event in Brussels (Belgium) today I head about this new body that could be influential in standardising the use of IPv6 for sensor networks going forward.

    IPSO Alliance: Promoting the use of IP for Smart Objects

    The domain of Smart Objects is vast. As sensors for light, pressure, temperature, vibration, actuators, and other similar objects evolve, new applications and solutions are being created and implemented. Indeed, "smart cities", "smart grid", home and building automation, industrial applications, asset tracking, utility metering, etc are all taking of IPv6's rich history and adaptability.

    Companies and consumers are ready for the level of automation that Smart Objects can bring. In order to satisfy the growing demand of information and standardization in the domain of the Internet of Things, more than 27 companies (IPSO Initial founders) have decided to join their efforts.

    The IPSO Alliance will perform interoperability tests, document the use of new IP-based technologies, conduct marketing activities and serve as an information repository for users seeking to understand the role of IP in networks of physical objects. Its role will complement the work of entities such as the Internet Engineering Task Force (IETF), Institute of Electrical and Electronics Engineers (IEEE) or the ISA which develop and ratify technical standards in the Internet community.

    The IPSO Alliance is an open, informal and thought-leading association of like-minded organizations and individuals that promote the value of using the Internet Protocol for the networking of Smart Objects.

    Press Coverage of Irish IPv6 Summit

    Minister Ryan and Micheal O Foghlu

    The picture shows Mícheál Ó Foghlú (Executive Director Research, TSSG) and the Eamonn Ryan (Minister of Communications, Energy and Natural Resources) at the opening of the Irish IPv6 Summit on Wednesday 28th January 2009. Over 150 delegates from industry and the public sector attended. Many had a technical networking background, and others had a decision making and/or policy role within their organisations.

    The main message of the event was that the current Internet infrastructure relies for growth on the availability of IPv4 addresses, and that all predictions now converge on exhaustion of the address space within the next 3 to 5 years. This is a very short time in terms of planning migration to a new network infrastructure. The only potential candidate to replace IPv4 is IPv6. Though there are many interesting research approaches that may lead to interesting alternatives, none can produce an agreed standard for deployment in the short time required.

    The TSSG were very happy to organise the event, with the Irish IPv6 Task Force, on Wednesday 28th January 2009. The event was streamed live over IPv4 and IPv6, and video clips of all talks, and PDF versions of all slides will be made available on the main event website.

    WIT published a Press Release.

    The event was covered in the Irish Times the following day in the Finance section, see the TSSG Press Page.

    RTE Radio recorded a special on-line feature on the event that can be streamed from RTE Special Feature.

    The event was supported by the TSSG (Waterford IT), HEAnet (Ireland's National Research Network) and DCENR (Department of Communications, Energy and Natural Resources).

    The event was sponsored by The Internet Society (ISOC), Ireland's Domain Registry (IEDR) and Hutchison 3G Ireland (Three).

    Irish IPv6 Summit (Wed 28th Jan 2009)

    Irish IPv6 Summit Logo

    Well, my blog has be quiet for over a month now as I have focused my energies on a number of things. Foremost amongst these is the IPv6 Summit that will take place all day tomorrow in Dublin Castle. We're very happy with the panel of speakers, including the opening by Minister of Communications, Eamon Ryan, and the two keynote speakers, Fred Baker (Cisco), who has a very prominent role in IETF standardisation, and Detlef Eckert (EU Commission), who is a senior policy advisor to DG-Information Society and Media, the unit in the EU Commission with responsibility for ICT policy.

    The other speakers are myself, opening the event in my role as Chair of the Irish IPv6 TF, John Boland (CEO of HEAnet), Ireland's national research network, Niall Murphy (Google), Dave Northey (Microsoft), Giorgio Lembo (Tiscali International Networks), John King (BT), Zoltan Gelencser (Hutchison3G UK), Ross Chandler (Eircom), David Malone (NUI Maynooth), and Nick Hilliard (Dublin Internet Neutral Exchange).

    Irish IPv6 Summit (Home Page)
    Irish IPv6 Summit Agenda (PDF)
    Irish IPv6 Summit Agenda (HTML)

    This is an impressive line up of technical and political awareness of the importance of understanding the next generation Internet protocol. The Internet is a huge success story that underpins much of the world’s ICT infrastructure today BUT “Peak IPv4” is nearly upon us. This will see the last central block of IPv4 addresses allocated to Regional Internet Registries (RIRs) at the end of 2010. The impact on users will be that they will not be able to get new public IPv4 addresses 12-18 months after that.

    This is not a complete doomsday scenario, the existing Internet will continue to work after the addresses run out. The problem is that the whole philosophy of the Internet is based on growth into new areas: bring more and more of the world's population on-line, bring more diverse devices on-line from mobile phones to built-in sensors in buildings. For this trajectory to continue, new addresses are needed. So it really makes sense for anyone upgrading a network today to invest in a solution that is at least IPv6 compatible, so that they have the option of migrating to IPv6 within the next 5 years when these shortage issues start to bite. As more and more people do switch over, it should make the argument easier --- this is a network effect problem where you need to get a critical mass of acceptance to create the right environment for it to become the obvious choice.

    Restoring an address abundance has many potential advantages. It re-enables the pure end-to-end model of the Internet where every device has a public address, and so, with due consideration of the security issues, could offer a service to any other device. In other words it re-enables the peer-to-peer potential of the Internet and low barrier to entry for new services.

    So if you are interested in the debate, register and come along tomorrow. If you cannot come we'll be streaming the event live over IPv4 and IPv6 (thanks to HEAnet), and we'll be making on-line videos of the talks, as well as the slides, available on-line after the event.

    HEA PRTLI Cycle 4: FutureComm

    On Monday and Tuesday this week we had our third meeting of partners of the HEA PRTLI Cycle 4 research programme FutureComm. The event was hosted by NUI Maynooth (both the Hamilton Institute, and the Dept. Sociology here are partners). The other partners are ourselves (TSSG in Waterford IT) and the Interaction Design Centre (University of Limerick).

    We're just starting to get to the stage where we may expose some of our internal discussions to the public, hence we've launched a simple public blog: HEA-FutureComm.

    The programme is quite innovative as it attempts to bridge the technical community working on the future of network and service management, from both Internet and Telecommunications perspectives, with a wider contextual social analysis of the issues around governance of networks and services, and an analysis of social networking and how it links to potential network and service dynamic reconfiguration.

    Internet Adoption Myths?

    In this excellent article Hannemyr: The Internet as Hyperbole Gisle Hannemyr argues that the often stated fact that Internet adoption was faster then other technology adoptions (such as radio, TV or telephone) is overstated. Thanks to Miguel.

    It is widely believed that the adoption rate of the Interュnet has exceeded that of earlier mass communication technologies by several magnitudes. This paper reviews the historic data related to some of these technologies, draws on actor-network theory as a framework for interpreting such data, traces the transformations and translation of this data in the public, political, and scientific discourse, and discusses the use of <> in modern society.

    Metaphors and Networks

    Saving the Net III: Understanding its Frames | Linux Journal

    Doc Searls makes an interesting argument about how the metaphors we use for the Internet/Web influence how we think about it. It contains an excellent set of references (e.g. Zittrain, Reed), so I'll be using this as starting point for my students as an aid to understanding the debates around the future of the Internet.

    Future Internet Assembly (Bled, March/April 2008)


    The TSSG is at the heart of EU funded research into the Future Internet. The TSSG also has Irish funding (from the HEA and SFI that funds related basic research into the management of future networks). The TSSG was well represented at the recent event in Slovenia: Future Internet Assembly (31st March - 2nd April 2008). This post tries to summarise TSSG Future Internet activity, EU-funded and Irish-funded, and how this range of expertise links to events like the one in Bled.

    The key point of this posting is to illustrate how the TSSG is at the centre of Future Internet activity in Europe. In addition to the active projects, and participation in the EU Technology Platforms, the TSSG has also led the way in building events that integrate the North American view of the Future Internet with the European view, in particular through the TridentCom event (held this year in Austria in March, chaired by Miguel ponce de Leon, and next year in Washington DC) chaired by our colleague and visiting Professor in Waterford IT, Thomas Magadanz (Fraunhofer FOKUS and the Technical University of Berlin).

    The TSSG's engagement in Future Internet activities builds upon our prior experience in communications infrastructure and services (and in particular the management challenges of heterogeneous environments including wireless access networks), and our experience in EU FP4, FP5, FP6 and FP7 projects from 1996-2008.

    TSSG active in EU Future Internet projects

    • 4WARD [IP FP7 ICT Call 1] (TSSG: partner)

      The 4WARD project is looking to the new architecture and design for the Future Internet and has set itself the task of creating a new approach to networking architecture that is more flexible and better adapted to present and future requirements.

    • EFIPSANS [IP FP7 ICT Call 1] (TSSG: partner)

      The EFIPSANS project aims at exposing the features in IP version six protocols that can be exploited or extended for the purposes of designing or building autonomic networks and services.

    • AutoI [STREP FP7 ICT Call 1] (TSSG: partner - coordinated proposal submission)

      The Autonomic Internet project will design and develop a self-managing virtual resource overlay that can span across heterogeneous networks, support service mobility, quality of service and reliability.

    • PERSIST [STREP FP7 ICT Call 1] (TSSG: coordinator)

      The Project PERsonal Self-Improving SmarT spaces (PERSIST) deals with personal smart spaces that a user carries with his mobile devices and that are able to interact in an ad hoc way. Thus, PERSIST complements the vision of a operator driven Pervasive and Context-Aware Computing environment (e.g. Daidalos I and II projects in FP6) by extending it to environments where neither network connectivity nor smart space features are available. Major research challenges of the PERSIST project are service provisioning and composition in ad hoc scenarios, context awareness and context semantics, pro-activity and learning and privacy and security issues. All of these objectives except security and privacy are covered by the Internet of Services Working Group of the Future Internet Assembly. PERSIST is a member of the Internet of Services Working Group and is active in the Security and Privacy cross-domain subgroup which interfaces to the Security and Privacy Working Group of the Future Internet Assembly.

    • Inco-Trust [CA FP7 ICT Call 1] (TSSG: coordinator)

      INCO-TRUST is an FP7 international cooperation project within the F5 Unit Security, bringing together researchers in ICT Trust, Security and Dependability from the EU, U.S., Japan, Australia, South Korea and Canada. The project will address problems where the interconnected trans-national world of “things” (and attacks, impact, enforcement) gives incentive to join forces with other countries. The topic areas include Future Internet, interlinked infrastructures and their protection.

    • Think-Trust [CA FP7 ICT Call 1] (TSSG: coordinator)

      Think-Trust Project is investigating Trust, Security, Dependability, Privacy and Identity from ICT and Societal Perspectives. The project and its Advisory Board (RISEPTIS) will be supported by targeted working groups from the stakeholder and research community that will address focussed issues and questions. These WG will focus on 1) Security, Dependability and Trust in the Future Internet and 2) Privacy and Trust in the Information Society. Its objective is to formulate recommendations on future policy and research priorities.

    • PII [IP FP7 ICT Call 2] (TSSG: partner)

      The PII (PanLab 2) project is a Pan-European laboratory infrastructure implementation project which has the objective to enable the federation of innovation clusters on a European level, applying the framework developed by the Panlab SSA in FP6, which consists of basic legal, operational, and technical rules.

    • Perimeter [STREP FP7 ICT Call 2] (TSSG: partner) Project kick-off is May 2008

      The Perimeter project is looking to establish a new paradigm of user-centrality for advanced networking. In contrast to network-centric approaches, user-centric strategies could achieve true seamless mobility putting the user at the centre rather than the operator enables the user to control his or her identity, preferences and credentials, and so seamless mobility is streamlined, enabling mobile users to be “Always Best Connected” in multiple-access multiple-operator networks of the Future Internet.

    • VITAL++ [STREP FP7 ICT Call 2] (TSSG: partner) Project kick-off is May 2008

      Emerging types of applications, rich in user-created or provider-created content, enabled by P2P technology, with high demands for network resources are rapidly changing the landscape of network requirements and operations creating new challenges in network and service management, configuration, deployment, protocols etc. P2P is primarily a technology that fosters self-deployment and self-organisation, thus, reducing operational costs, while it achieves optimised resource utilisation for the deployed applications and services. In contrast, IMS as a control plane technology primarily addresses issues of heterogeneity of access technologies, addressing schemes, AAA, security and mobility management. This project's major objective is to combine and experiment with the best of the two worlds, namely, IMS-like control plane functionality and P2P technology giving rise into a new communication paradigm that will bring a wide range of benefits. The key to achieving this objective, is to put this paradigm under strenuous experimentation, carried out under realistic network conditions using popular applications. To this end, the project is putting together a pan-European testbed comprised of existing geographically distributed test sites integrated by IMS technology. This will be thoroughly tested by reference content applications and services that use P2P technology as a means for their distribution and achieving satisfactory QoS levels through network resource optimisation algorithms rather than non-scalable QoS reservation operations.

    (Note on types of EU project: IP = Integrated Project; STREP = Strategic Research Project; CA = Coordinated Action; SSA = Strategic Support Action).

    TSSG active in EU Technology Platforms

    All of the EU Technology Platforms in which the actively participate have signed up to support this Future Internet activity in the EU. Technology Platforms are the EU's mechanism for allowing key industrial sectors to define the research challenges for the sector, providing a mechanism for these challenges to be integrated into the research funinding programmes of the EU Commission. The descriptions below describe the EU-TPs activity at the Future Internet Assembly in Bled in March 2008:

    • eMobility (TSSG: board member)

      Objective: To reinforce Europe's leadership in mobile and wireless communications and services and to master the future development of this technology, so that it best serves Europe's citizens and the European economy.

      eMobility participated to a number of the breakout sessions at the Future Internet Assembly. WIT/TSSG were responsible for finding a speaker from eMobility for session BO5 Security and assisted with the presentation entitled security cross-issues as seen from the perspective of the eMobility European Technology Platform made during the breakout session. As Steering Board member, WIT/TSSG were requested to help with the questionnaire for eTPs during the preparation phase of the event.

    • NEM (TSSG: board member)

      Networked and Electronic Media (NEM) is one of the European Industrial Initiatives, also known as Technology Platforms, established by relevant key European stakeholders, which address the convergence of media, communications, consumer electronics, and IT as a wide opportunity for future growth, by taking advantage of generalized broadband access, increased mobility, availability of richer media formats and contents, as well as new home networks and communications platforms.

      NEM were very active during the sessions, especially the BO session on content. They also participated to the other sessions and, for example, presented the security challenges to the BO5, which included ensuring data integrity and resiliency, sustainable user privacy and trustworthiness and content management. This calls for interoperability and scalability of security measures. WIT/TSSG is the leader in an activity within NEM called NEM Security. WIT/TSSG is representing NEM Security in a cross platform panel session on ICT TSD in July 2008 at the DEBS 2008 conference.

    • NESSI (TSSG: member)

      The NESSI (Networked European Software and Services Initiative) Technology Platform is a public/private partnership that aims to develop and implement a common European strategy for achieving global leadership in software and services. NESSI addresses European research in services architectures and software infrastructures including Grids and will develop technologies, strategies and deployment policies fostering new, open, industrial solutions and societal applications that enhance the safety, security and well-being of citizens. Software and services have become a strategic capability for industry and society. Advances in Web services, Grid technologies Software and communication networks are changing the Internet, wireless and audiovisual worlds into a worldwide platform for building and delivering distributed applications, services and information. Today, this trend is emerging as a market for "on-demand services" that build on web services, Grid technologies and SOAS. This will have a profound effect on existing IT business models. Rather than customers having to adapt their processes to make use of off-the-shelf software, they will be able to procure, relatively cheaply, tailored systems that directly support their work and that can evolve in step with their businesses.

      NESSI were active during most sessions, especially the BO session on services. A representative also presented in the Security session on the implications of virtualization for security and the related specifications of security requirements in the virtual environment. WIT/TSSG is a member of the NESSI Working group on Trust, Security and Dependability.

    TSSG in Irish-funded Future Internet projects

    • AMCNS (Science Foundation Ireland, SFI PI Cluster)

      The “Autonomic Management of Communications Networks and Services” research programme addresses the essence of Autonomic Management, which is the ability for a system to self-govern its behaviour within the constraints of the business goals that the system as a whole seeks to achieve. It aims to develop a reference architectural framework for autonomic communications, which will facilitate the definition, creation, deployment and management of communications services in line with high level business goals, but without the requirement for significant human intervention. Fundamental part of the work is the use of information modelling to capture knowledge relating to network capabilities, environmental constraints and business goals/policies, together with ontological engineering to provide inferencing capabilities. This foundation is supplemented by reasoning and learning mechanisms to enhance and evolve this knowledge. Policy-based network management systems incorporating translation/code generation will use this knowledge to automatically configure network elements in response to changing business goals and/or environmental context. This realises an autonomic control loop, in which the system senses changes in itself and its environment, analyses these data to ensure that business goals and objectives are being met; expedites changes should these goals and objectives be threatened, and observes the result to ensure that closed-loop operation is maintained.

    • Serving Society (Higher Education Authority, HEA PRTLI Cycle 4)

      The proposed research programme aims to address the following long-term research question: How do we realise future communications services and infrastructure that reflect changing individual and societal preferences, and that can be effectively managed to ensure delivery of critical services? The project will adopt an inter-disciplinary approach to the specification of artefacts including models, algorithms, processes, methodologies and architectures that will collectively constitute a framework that can guide the realisation of future communications environments to effectively provide critical societal services and, in doing so, support and sustain interactions between various communities of users. Three closely-linked strands of research (and one smaller sub-strand) constitute the project: Future Communications Services, Future Communications Networks, Capturing and Addressing Societal Needs.

    • IMS ARCS (Enterprise Ireland, EI ILRP)

      IMS is the IP Multimedia Subsystem, a core component of the mobile telephony architecture defined by the 3GPP, and of the fixed-mobile convergence standards defined by ETSI TISPAN. IMS can be viewed as an important aspect of the telecommunication industry's view of how the Future Internet will be structured. The IMS ARCS project aims to develop IMS expertise within the Irish Software and Telecommunications Industry. The project stakeholders consists of an academic consortium lead by the Telecommunications Software & Systems Group (TSSG) and a number of industry partners including operators, hardware and software vendors, and mobile service providers and developers. The IMS ARCS project is developing a set of prototype services together with a set of common enablers which will serve as exemplars of what can be achieved using IMS technology and will help springboard the creation of innovative new IMS products and services within the stakeholder group. A further objective of the project is the creation of a national centre of excellence in IMS technology and the setup a world class IMS test environment which will be operated by TSSG, and which will be accessible by companies developing IMS focused products.

    Bled Declaration

    Current Internet: Success & Challenges

    With over a billion users world-wide, the current Internet is a great success – a global integrated communications infrastructure and service platform underpinning the fabric of the European economy and European society in general. However, today's Internet was designed in the 1970s for purposes that bear little resemblance to current and foreseen usage scenarios. Mismatches between original design goals and current utilisation are now beginning to hamper the Internet’s potential. A large number of challenges in the realms of technology, business, society and governance have to be overcome if the future development of the Internet is to sustain the networked society of tomorrow.

    Future Internet: Vital to continued economic Growth in Europe

    In the future, even more users, objects, services and critical information infrastructures will be networked through the Future Internet which will underpin an ever larger share of our modern and global economies. It is therefore time to strengthen and focus European activities on the Future Internet to maintain Europe’s competitiveness in the global marketplace.

    A significant change is required and the European Internet scientific and economic actors, researchers, industrialists, SMEs, users, service and content providers, now assert the urgent necessity to redesign the Internet, taking a broad multidisciplinary approach, to meet Europe’s societal and commercial ambitions.

    Future Internet: Addressing the Challenges through EU Collaboration & Cooperation

    EU member states have already committed, through the renewed Lisbon Agenda and the i2010 initiative, €9.1 billion of funding, as part of a public-private partnership, for ICT research over the duration of FP7. However, we must ensure that, within this, continuous and long term support is given to the design of the Future Internet as a key element of the future networked society. It is of strategic importance for Europe to fully engage in the conception, development and innovation of a Future Internet ensuring the long term growth of the ICT sector, full support to an ICT based economy, and the elimination of the digital divide for all citizens.

    The research projects assembled here in Bled represent the first phase of this public-private partnership, a joint investment of over €400 million, that recognises the challenges above and emphasises a concerted and comprehensive process of redesign, based upon novel network, service, trust, security and content technologies together with strong initiatives towards new innovations in societal, governance and service domains, in order to ensure that the Future Internet fulfills its potential.

    More specifically, building upon the obligations of our individual project contracts and the goals of the Strategic Agendas of the European Technology Platforms, we confirm our ambitions include:

    Fostering Favourable Conditions through Coordinated Action

    • Coordinate our efforts to foster cross-disciplinary innovation and creativity.
    • Work together through a European Future Internet Assembly of research projects strengthening cross-discipline activity and optimising the impact of our actions.
    • Cultivate and foster the skills and knowledge required to develop the Future Internet.
    • Create the conditions for the deployment of services and service oriented systems.
    • Communicate through open standards for Future Internet technologies and architectures.
    • Open the European Future Internet Assembly to new projects and actors over time to widen the coordination and consistency of the action.

    Jointly Designing, Developing and Experimenting

    • Services and networking architecture for the Future Internet.
    • Location independent, interoperable, coherent, consistent, scalable, pervasive, reliable, secure and efficient access to a coordinated set of services.
    • Tools supporting collaborative business models and social network applications.
    • Technologies ensuring the robustness and security of the networks, managing identities, protecting privacy and creating trust in the on-line world.
    • Approaches and tools to leverage the full potential of the Internet of Things.
    • Capabilities for supporting the creation, sharing, locating and delivery of new-media content.

    Increasing Awareness at Policy Level

    • Raise awareness of the economic, policy and regulatory issues as identified by the newly proposed European Future Internet Assembly, the UN Internet Governance Forum, the OECD and the European regulatory frameworks.
    • Contribute to the definition of European positions within global forums and arenas.

    Call for European action towards the Future Internet

    To help us meet these major challenges, we call on the:

    • European Member States to strengthen and coordinate their national R&D efforts and initiatives toward the Future Internet.
    • European Commission to stress the vision and amplify the related R&D in order to drive Europe ahead of tomorrow’s Internet transformations in the way we work, live, and interact.
    • European Member States and the European Commission to support the creation and activities of the European Future Internet Assembly proposed in this declaration.

    This declaration is endorsed by the following European Technology Platforms and European Research Projects

    Accession to this declaration is open to existing and future EU Projects that wish to actively contribute

    The night the IETF turned off IPv4

    This is a good summary of the experiment at a recent IETF to disable IPv4 for one hour to test the issues with using an IPv6-only network infrastructure.The night the IETF turned off IPv4

    After working on the new Internet Protocol version 6 (IPv6) for a decade and a half, the Internet Engineering Task Force decided it was time to turn off the old protocol (IPv4 or just IP). So this is what they did for an hour on the network used at the IETF meeting in Philadelphia this week. Network traffic plummeted from some 30Mbps to around 3Mbps as the meeting attendees who had IPv6 enabled could now only get at IPv6-reachable destinations on the Internet. Leslie Daigle, chief Internet technology officer for the Internet Society, who coordinated the IPv4 outage, considers the outage a success.

    Views on Network Management

    This article links to a well argued draft paper Why Telcos Don’t Get Networks. Abstract:

    If there is a sector of the economy that should embrace network-based thinking, it is telecommunications. Surprisingly, the opposite is the case. The leading firms building telecommunications and Internet infrastructure increasingly emphasize consolidation, hierarchy, and exclusive control, rather than collaboration and decentralization. Regulators are dismantling legal frameworks that once promoted openness and interconnection, in favor of misguided efforts to incent proprietary investment. And many scholars, even those challenging the current drift of policy and business models, embrace a static worldview that is a relic of earlier eras. Network-based strategies are thus hard to find today in the so-called "network industries," even as such ideas flourish in adjacent digital information markets. This chapter explores the origins of this paradox, describes its manifestations in the legal and business environment, and traces a more hopeful future.

    Metcalfe’s Law: more misunderstood than wrong?

    An interesting discussion of Metcalfe’s Law Metcalfe's Law: more misunderstood than wrong?

    The industry is at it again–trying to figure out what to make of Metcalfe’s Law. This time it’s IEEE Spectrum with a controversially titled “Metcalfe’s Law is Wrong”. The main thrust of the argument is that the value of a network grows O(nlogn) as opposed to O(n2). Unfortunately, the authors’ O(nlogn) suggeston is no more accurate or insightful than the original proposal. ... The typical statement of the law is “the value of a network increases proportionately with the square of the number of its users.” ... The unit of measurement along the X-axis is “compatibly communicating devices”, not users. ... Title of graph: "The Systemic Value of Compatibly Communicating Devices Grows as the Square of Their Number"

    The Network Neutrality Debate

    This is a great rant that pokes holes in just about everyone's arguments: LXer: Network Neutrality and an Internet with Vision.

    In recently-aired plans by telephone companies, content providers who are willing to pay extra would get their content delivered at a higher bandwidth. While it's easy to wax indignant over telephone companies' presumptuousness in deciding what packets should travel at what times, it's harder to step back and take in the economic issues driving the proposed change. And there are technical questions about it as well.

    CAIDA IPv6 Topology Maps


    I was interested to see that CAIDA had released an updated IPv6 topology map based on statistics gathered in January 2008. The graphs are a visualisation of ASs (Autonomous Systems) in the Internet based on the number of routes between them. ASs are usually controlled by a single owner, and thus this diagram tries to capture logical complexity of the network of networks that is the Internet.

    These graphs create an interesting picture of the complexity of the Internet. For comparison have a look at the IPv4 topology map (multiple versions). If you look at these you'll see that the current IPv6 topology is as complex as the IPv4 Internet in 2000, at the height of the dot com boom. Of course the current IPv4 topology is more complex (latest shown currently is 2007).

    Ever since I discovered these graphs I have thought that they were a great way to visualise the complexity of the Internet (IPv4 and IPv6).

    Discussion of NAT (and IPv4 address deplation)

    Nice to see that we are starting to think of the good things that NAt gave us, as well as planning the move to IPv6 where it will no longer be required. I think this post has it right, NAT served a purpose, now move on.

    As IPv6 Deploys, Will We Look Back on NAT as the Ugly Step Sister or Unsung Hero?

    Internet prediced to reach zettabyte (annual US traffic)

    TDP - Estimating the Exaflood

    IP Traffic Projection Graph

    From YouTube, IPTV, and high-definition images, to “cloud computing” and ubiquitous mobile cameras—to 3D games, virtual worlds, and photorealistic telepresence—the new wave is swelling into an exaflood of Internet and IP traffic. An exabyte is 10 to the 18th. We estimate that by 2015, U.S. IP traffic could reach an annual total of one zettabyte (1021 bytes), or one million million billion bytes.

    IPv6 Address Added for Root Servers in the Root Zone

    ICANN | IPv6 Address Added for Root Servers in the Root Zone

    MARINA DEL REY, Calif.: The Internet Corporation for Assigned Names and Numbers today took another step along the path of deployment for the next-generation IPv6 Internet addressing system.

    IPv6 addresses were added for six of the world’s 13 root server networks (A, F, H, J, K, M) to the appropriate files and databases. This move allows for the possibility of fuller IPv6 usage of the Domain Name System (DNS). Prior to today, those using IPv6 had needed to retain the older IPv4 addressing system in order to be able to use domain names.

    "The ISP community welcomes this development as part of the continuing evolution of the public Internet,” said Tony Holmes, chair of ICANN’s Internet Service and Connectivity Provider Constituency. “IPv6 will be an essential part our future and support in the root servers is essential to the growth, stability, and reliability of the public Internet.”

    Name server software relies on the root servers as a key part in translating domains like “icann.org” into the routing identifiers used by computers to connect to one another. In 2007 the ICANN Security and Stability Advisory Committee concluded that ICANN should move forward with the enhancement of the DNS root service by adding IPv6 addresses for the root servers.

    As more and more devices connect to the Internet they require unique Internet Protocol (IP) addresses. The remaining free pool of unassigned IPv4 addresses is being depleted by the growth of the Internet. IPv6 is the addressing protocol that increases the unique IP addresses from the 4 billion available in IPv4, to more than 340 trillion trillion trillion.

    “Today’s addition of IPv6 addresses for the root servers enhances the end-to-end connectivity for IPv6 networks, and furthers the growth of the global interoperable Internet,” added David Conrad, ICANN’s Vice President of Research and IANA Strategy. “This is a major step forward for IPv6-only connectivity and the global migration to IPv6.”

    Further technical information on the move is available at http://www.iana.org/reports/root-aaaa-announcement.html

    Ireland has 2nd higest percentage of IPv6 DNS entries

    In this interesting analysis of actual IPv6 deployment (for http - web servers, smtp - email server and dns - domain name servers) Examining Actual State of IPv6 Deployment it seems that Ireland is doing quite well in terms of DNS with 14% of our sites having an IPv6 address - not a high score but 2nd only to Lithuania. We have don't fare so well in have 4.1% of our mail servers IPv6 enabled - above the median in 35th place, and 38% of our web servers enabled - below the median around 80th.

    I am here in Amsterdam speaking at a Marcus Evans conference on 9th Annual Signalling Systems for Future Telecoms (Exploring the Future of Networks and Interconnect for an All-IP World), quite a mouthful but a really good event.

    The first talk today was from Martin Stiemerling (NEC) who co-chairs the IETF nsis activity: Next Steps in Signaling (nsis) Charter. This is a fascinating development allowing flexible in-band signalling and QoS (Quality of Service) negotiation over IP routed networks.

    As usual the main problem with any inter-domain QoS across the Internet is a business issue, rather than a technical one of standards: why would any network operator give some other operator's customers priority on their networks, so most QoS systems are applied within a single network autonomous system only, administered by a single operator. So just because I think my VoIP is important, doesn't mean every operator in my path will agree, even if the standards allow them to.

    Summary of IPv6 Announcements

    An excellent summary of major announcments about IPv6 this year: The Year IPv6 Made it to Major League

    May 6th 2007: ARIN board of trustees passes a resolution advising the Internet community that migration to a new version of the internet protocol, IPv6, will be necessary to allow continued growth of the internet.

    June 29th 2007, Puerto Rico: ICANN Board resolution states that: The Board further resolves to work with the Regional Internet Registries and other stakeholders to promote education and outreach, with the goal of supporting the future growth of the Internet by encouraging the timely deployment of IPv6.

    Oct 26th 2007 at the RIPE 55 meeting in Amsterdam: “Growth and innovation on the Internet depends on the continued availability of IP address space. The remaining pool of unallocated IPv4 address space is likely to be fully allocated within two to four years...the deployment of IPv6 is necessary for the development of future IP networks”

    Nov 15th 2007: IGF meeting, Rio de Janeiro, chairman’s report: “Panelists also discussed the eventual exhaustion of ICANN’s reserve of unassigned IPv4 addresses.”

    It was made clear that this would not cause the Internet to fail, but this was used to indicate the importance of the effort to bring the IPv6 network on-line and the need for the full interoperability between the IPv4 and IPv6 networks.

    This is but a small sample of the fast growing visibility IPv6 acquired this year, 2007.

    The internet ecosystem, ranging from network Operator Groups (NOG) to peering forums to Regional Internet Registries (RIR) to ICANN, to IANA and even the United Nations sponsored Internet Governance Forum (IGF), had IPv6 quite high on its agenda this year. This rather sudden surge has taken at least some of us, amongst long term IPv6 proponents and advocates, by surprise, as it took close to a decade, lots of persistence, lots of convincing and periods of doubt, to get to this point. This is a period those involved in the early IPv6 experiments and deployment in the Research and Education Networks, the IPv6 Forum since its beginnings back in 1999, should savor and enjoy. Not to mention those who fathered RFC’s, spent time at IETF and late nights on numerous mailing lists and never ending e-mail strings.

    Cisco IPJ - lots of good IPv6 discussions

    The most recent issue of the Cisco IPJ (Internet Protocol Journal), that is available for free on-line, has a number of very interesting articles on IPv6.

    First Geoff Huston, APNIC updates us with his view of the big picture on IPv4 depletion, and the slow pace of IPv6 roll out. He is right to point out that a continued dual-stack strategy, that many seem to favour, will continue to require IPv4 addresses, and will thus become untenable when the IPv4 addresses themselves run out. There isn't much time to deploy IPv6 everywhere, within the IPv4 depletion timescale.

    Then Iljitsch van Beijnum gives his views on IPv4 address consumption, trying to focus not just on the /8 block allocations from IANA to the RIRs, but on the subsequent allocation by the RIRs to ISPs and others.

    Then Leo Vegoda talks about the use of unregistered IPv4 address space: "Many organizations have chosen to use unregistered IPv4 addresses in their internal networks and, in some cases, network equipment or software providers have chosen to use unregistered IPv4 addresses in their products or services." He discusses the potential problems that could ensue.

    On a separate, but related theme, that of security for IP networks, Kunjal Trivedi, Cisco Systems and Damien Holloway, Juniper Networks discuss secure multivendor networks.

    This issue of the IPJ could thus be seen as the definitive one in terms of summarising the key issues of IPv4 depletion, and IPv6 deployment. We have 2 years before the /8 IANA pool runs out, and a further 12-18 months before the RIRs then cannot comply with requests for new IPv4 addresses. I suggest everyone who is interested in the future of the Internet as it is now (not some abstract new network we haven't thought of yet) read these papers and become conversant with the arguments, and then start deploying IPv6 as quickly as possible.

    IPv6 SHIM6 Interoperability Testing with Moonv6 in University of New Hampshire

    Over the summer Irish National IPv6 Centre have conducted interoperability tests with Moonv6 in the InterOperabilty Lab (IOL) in the University of New Hampshire: UNH-IOL Tests IPv6 for the Enterprise.

    The university lab partnered with the Waterford Institute of Technology in Ireland to extend the testing into less familiar territory. This portion of the testing focused on an innovation not possible with today’s Internet called Site Multihoming by IPv6 Intermediation, or SHIM6 for short. Of special interest in financial transactions, SHIM6 is an IPv6-only failover function that kicks in if one side of a link goes down, automatically rerouting the connection without affecting the download in progress.

    IPv6 is the successor to the current IP infrastructure that underlies data in today’s Internet and enterprise networks. The new protocol greatly enlarges the pool of IP addresses needed to network new servers, laptops, phones, printers, etc. While some geographies have already run out of IP addresses, it has been predicted that North America will face IPv4 address space exhaustion between the years 2010-2012. IPv6’s increased address space is expected to make better use of emerging technology areas like VoIP, video and various interactive multimedia applications as well.

    Other benefits touted for IPv6 include simplified network architecture, an increase in new services, and increased number of network nodes, built-in security, and the ability to "plug and play" devices that are IPv6 enabled. After first getting involved with the protocol in the late 1990s, the UNH-IOL has been actively testing and debugging IPv6 devices on the Moonv6 network since 2003.

    This work is related to the EU FP6 IST project ENABLE that looks at many aspects of IPv6 mobility, and promotes suitable changes to the IETF standards.

    Zimbie launches beta Instant Messaging client/server for automated IM-"bots"

    Another TSSG spin-out company, Zimbie (not fully launched yet), has just released a public beta of their software that allows users to easily setup automated Instant Messaging "bots" (robots to automate tasks). The idea is that what appears to be another friend on your IM buddy list actually talks to a server that performs some task and returns the result as text in an IM chat. The Zimbie client itself can allow the bot to return more complex data than just text, but you don't have to use teh Zimbe client to access a bot, any IM reader will do. The aim of the beta release is to demonstrate the ease of setting up a bot without doing any programming.

    The beta release has attracted some attion on the blogosphere: Blognation Conor O'Neill), Cloudlands (John Breslin), KillerStartups, and more.

    Mapping the Internet


    This is an interesting new approach to mapping the Internet Technology Review: Mapping the Internet. The work draws on the research project DIMES, and has some interesting interactive graphing tools, and a downloadable client to join in the mapping project.

    It is interesting to compare this to the excellent work done at CAIDA, such as the AS-level topology maps of IPv6 and IPv4, using these tools (skitter probes, BGP table analysis, and ancillary tools).

    Returning to the magazine article from Technology Review this extract gives a good flavour of the contents:

    It's the first study to look at how the Internet is organized in terms of function, as well as how it's connected, says Shai Carmi, a physicist who took part in the research at the Bar Ilan University, in Israel. "This gives the most complete picture of the Internet available today," he says.

    While efforts have been made previously to plot the topological structure in terms of the connections between Internet nodes--computer networks or Internet Service Providers that act as relay stations for carrying information about the Net--none have taken into account the role that these connections play. "Some nodes may not be as important as other nodes," says Carmi.

    The researchers' results depict the Internet as consisting of a dense core of 80 or so critical nodes surrounded by an outer shell of 5,000 sparsely connected, isolated nodes that are very much dependent upon this core. Separating the core from the outer shell are approximately 15,000 peer-connected and self-sufficient nodes.

    Take away the core, and an interesting thing happens: about 30 percent of the nodes from the outer shell become completely cut off. But the remaining 70 percent can continue communicating because the middle region has enough peer-connected nodes to bypass the core.

    With the core connected, any node is able to communicate with any other node within about four links. "If the core is removed, it takes about seven or eight links," says Carmi. It's a slower trip, but the data still gets there. Carmi believes we should take advantage of these alternate pathways to try to stop the core of the Internet from clogging up. "It can improve the efficiency of the Internet because the core would be less congested," he says.

    To build their map of the Internet, published in the latest issue of the Proceedings of the National Academy of Sciences, the researchers enlisted the assistance of 5,000 online volunteers who downloaded a program to help identify the connections between the 20,000 known nodes.

    The closest I can find to a full academic paper on this, rather than the magazine style article linked above, seems to be based on slightly earlier work very similar to CAIDA's, is an AS level topology analysis (paper).

      author = {Shai Carmi and Shlomo Havlin and Scott Kirkpatrick and Yuval Shavitt and Eran Shir},
      title = {MEDUSA - New Model of Internet Topology Using k-shell Decomposition},
      url = {http://www.citebase.org/abstract?id=oai:arXiv.org:cond-mat/0601240},
      year = {2006}


    The k-shell decomposition of a random graph provides a different and more insightful separation of the roles of the different nodes in such a graph than does the usual analysis in terms of node degrees. We develop this approach in order to analyze the Internet's structure at a coarse level, that of the "Autonomous Systems" or ASes, the subnetworks out of which the Internet is assembled. We employ new data from DIMES (see this http URL), a distributed agent-based mapping effort which at present has attracted over 3800 volunteers running more than 7300 DIMES clients in over 85 countries. We combine this data with the AS graph information available from the RouteViews project at Univ. Oregon, and have obtained an Internet map with far more detail than any previous effort. The data suggests a new picture of the AS-graph structure, which distinguishes a relatively large, redundantly connected core of nearly 100 ASes and two components that flow data in and out from this core. One component is fractally interconnected through peer links; the second makes direct connections to the core only. The model which results has superficial similarities with and important differences from the "Jellyfish" structure proposed by Tauro et al., so we call it a "Medusa." We plan to use this picture as a framework for measuring and extrapolating changes in the Internet's physical structure. Our k-shell analysis may also be relevant for estimating the function of nodes in the "scale-free" graphs extracted from other naturally-occurring processes.

    I am going to try and find out some more about this very interesting work, and I'll update this posting to reflect new information as I receive it.

    Telecoms.com – News, Events and research for the telecoms industry

    It is good to see emerging consensus in the telecommunications standardisation community on the use of IMS for Fixed Mobile Convergence (FMC). Here it is reported that ETSI TISPAN and 3GPP have agreed how to proceed with the IMS Release 8 process.

    ETSI TISPAN, the European standards body for the fixed-line half of the Next Generation Network world, this week agreed terms with mobile standards body, the 3GPP, on how to prevent the fixed and mobile versions of IMS from wandering apart.

    IMS originated with TISPAN before being taken up by 3GPP for UMTS R99/5, but since then, the fixed-line and co-ax people have become more interested in the idea again. Both standards committees have been co-existing peacefully but perhaps not as happily as one might like.

    The development of a Common IMS - common to fixed, cable and mobile networks - is going to go ahead in a 3GPP group, Services Specification SA-1, after a decision at last week's 3GPP plenary meeting in Busan, South Korea.

    The job has to be done by the end of 2007 in order to be ready for the launch of UMTS Release 8, or "the IMS you can deploy" as some people call it.

    Stephen Hayes, of Ericsson and 3GPP TSG-SA chair, said: "Over the next few months we must stabilise the Release 8 requirements and absorb the incoming Common IMS work."

    IPv6 Alloactions to Enterprises in Europe - a problem?

    In this excellent article Concerns grow over IPv6 migration - ZDNet UK the issues that effect the widespread adoption of IPv6 addressing within the enterprise networking community are addressed. It looks like the time has come to open up allocations more for enterprises and not just ISPs. I've worked with Tim Chown of the University of Southampton and the UK IPv6 Task Force on a number of activities, including the EU IPv6 Cluster -- a forum for interaction between various EU projects involved in IPv6. He has his finger on the pulse of the technical issues and has a good understanding of the business issues, so I respect his opinion on this matter. Note also the underlying message, as articulated here on a number of occasions, that even the conservative estimates of IPv4 exhaustion are converging on 2010 and 2011, not very far away.

    Enterprise Ireland IMS Workshop


    On the 5th June Enterprise Ireland hosted a workshop on IMS (the IP Multimedia Subsystem that is the standard at the heart of emerging data and voice in Fixed-Mobile Convergence for the telecommunications industry). The main guest speaker was our colleague Professor Thomas Magedanz of Fraunhofer Institut für Offene Kommunikationssysteme FOKUS, Berlin; he's also a visiting professor in Waterford Institute of Technology working with the TSSG on a number of Irish and EU funded research projects. Amongst other things in his presentation he was promoting his Open IMS Playground, which we use as an integrated testbed between the TSSG and FOKUS.

    The TSSG has started a website to track the Enterprise Ireland ILRP (Industry-Led Research Programme) IMS ARCS, in which FOKUS are a partner, and a recent posting on that site summarises the purpose of the workshop, and gives links to all the presentations made EI IMS Workshop | IMS ARCS Project.

    In fact I was originally due to share the platform and speak at this Enterprise Ireland workshop covering some background on the TSSG, and giving some initial details of the new IMS ARCS programme. Robert Mullins of the TSSG deputised for me and gave this presentation.

    So watch this space for future news on the TSSG's research in IMS, or track the IMS ARCS project directly on its own website. RSS feeds of the blogs are available as well.

    IMS ARCS is an Industry Lead Research Programme (ILRP) lead by the Telecommunications Software & Systems Group (TSSG) in Waterford. The IMS ARCS project is building a platform to facilitate the creation of IMS based services so that companies can tap into this market more quickly and easily, while ensuring consumers are not swamped by the resultant proliferation of services. As part of this work, a world class IMS Test Bed will be set up by TSSG.

    The vision of the IMS ARCS project is an environment where end-users can be immersed in a world of diverse IP-based media, voice or data services that can be received off any number of network types. The IMS ARCS platform will allow services to be selected and personalised based on the everyday needs of the end-user and on their current context. Every user’s experience of the network and its services will be differentiated by the user’s defined requirements, their past usage and their current context.

    These services will be supported by the provisioning of both existing and next generation network technology including both scalable and seamless integration of multiple heterogeneous networks, and ad-hoc and sensor networks. This will encourage and empower network and service operators to create new business opportunities and profitable services in an integrated mobile world.

    OMTP (Open Mobile Terminal Platform) Announces Requirements for IMS

    The OMTP (Open Mobile Terminal Platform) announced on 12th June 2007 that it had completed its set of requirements that lay the foundations for the seamless deployment of IMS (IP Multimedia Subsystem) applications and services and pave the way for a more consistent end-user experience.

    While many in the mobile industry believe that IMS will play a significant role in the future of data services, there are issues over the practicalities of deployment, which need addressing to enable IMS to truly deliver on its potential:

    • The applications that will built on IMS must be able to consistently access any necessary services;
    • The way in which applications respond upon receiving incoming IMS events must be defined;
    • The end-user must have a consistent and coherent experience;
    • Specifications must be consolidated and tiered for widespread uptake.

    In its current form the IMS proposition fails to sufficiently address these four key areas and falls short of the full end-to-end experience that is required. OMTP’s requirements detail the steps needed to address these fundamental issues.

    Tim Raby, OMTP CEO commented, “Despite the issues around its deployment, IMS delivers a host of potential benefits for operators, not least the ability to improve Quality of Service for end-users. For this to become a reality however there is a certain amount of ‘knitting’ needed to join up various elements. Our requirements give clear guidance to ensure IMS has the opportunity to deliver on its promises.”

    Irish ENUM Launches

    My colleague Miguel posts on the recent launch of the Irish ENUM service Miguel Ponce de Leon: ENUM Services launched in Ireland. His posting gives the high level overview of what public ENUM is supposed to be, and how close this offering in Ireland is to delivering on this. The downside seems to be the requirement for a validation every six months with a fee that makes it more expensive to maintain a public ENUM entry than an Internet domain name registration.
    In essence the public ENUM service links a telephone number to an IP address allowing the integration of Internet voice services and telephony. It is like a top level domain (TLD) for +353 (the international code of Ireland) in the same way that there is a TLD for .ie (the Internet country code domain for Ireland).
    Interesting I discovered a while ago that there is a parallel movement, championed by the GSMA (the GSM Association of mobile operators) to create a private "on net" ENUM as an alternative to this public ENUM infrastructure. Note that in telecommunications speak "on net" means on the operators' private networks, i.e. not on the public Internet; logical from their perspective if a bit confusing at first if you are coming from an Internet perspective (what we normally think of as "the net").
    Linguistic niceties aside, the potential problem with the open ENUM as illustrated by this Irish launch is that it is in effect publishing your telephone number for the world to see via an open database, so that potentially it could lead to similar problems of spamming that we see when email addresses are publicly exchanged.
    The promise of the private ENUM, as an alternative infrastructure using similar technologies, is that your mobile operator will protect your privacy and only give the information to other valid operators (that could include Internet-based VoIP providers who have paid to be part of the scheme. They have ample experience of this type of information exchange between operators through the use of the roaming agreements that allow us all to make and receive calls and SMS text messages anywhere in the world. Whilst there has been some criticism of expensive roaming changes, everyone agrees it is an invaluable service.
    I have noted before that I feel that it it is no coincidence that this solutions to the business problem of information exchange between operators arose in the European Union, a strange political beast where independent nation states have agreed to sacrifice some of their sovereignty in exchange for lasting pace and economic stability. It means we are constantly debating where the line between sovereignty and shared rules lies, and it places us in a good position to develop models that work where international boundaries need to be crossed, and everyone's opinions and rights need to be given due credit. Alternatively US and Chinese solutions tend to assume one size fits all, and are less likely to sit well with smaller countries jealous of their own ways of doing things. It takes all sorts of course, but I feel the EU has a lot to offer in developing working solutions for cooperating countries, legal systems, and shared critical infrastructures, such as the Internet and the telephone network, that cross these boundaries.

    The Grand Unifying Theory of Enterprise Computing: 2.0 (Sean McGrath, ITworld.com)

    A provocative side-swipe from Sean McGrath on enterprise computing ITworld.com - The Grand Unifying Theory of Enterprise Computing: 2.0

    The nub of his argument has some validity:

    If the details of all of this do not interest you, here is the takeaway: you cannot design away the network - you can only hide it behind tall banks of dollars bills. There are those who do not believe this of course. Everything - including truth - appears to be relative to a given point of view.

    ARIN Board Advises Internet Community on Migration to IPv6

    Well the mood is really shifting towards IPv6 in May 2007. Within the one month we have revised predictions of the IANA /8 IPv4 address pool exhaustion (Dec 2009/Jan 2010) from Geof Houston, and an announcement from ARIN that they now encourage people to move to IPv6.

    ARIN Board Advises Internet Community on Migration to IPv6.

    On 7th May 2007, the ARIN Board of Trustees passed a resolution advising the Internet technical community that migration to a new version of the Internet Protocol, IPv6, will be necessary to allow continued growth of the Internet.

    Internet Protocol defines how computers communicate over a network. IP version 4 (IPv4), the currently prevalent version, contains just over four billion unique IP addresses, which is not enough to last indefinitely. IPv6 is a replacement for IPv4, offering far more IP addresses and enhanced security features. To date, ARIN has performed technical coordination of both versions and has not advocated one over the other.

    Thanks to David Malone of The Hamilton Institute in NUI Maynooth for alerting me to the ARIN announcement.

    WebCamp on Emerging Mobile Internet in UCD 17th May 2007

    Well I went to the WebCamp on the Emerging Mobile Internet (UCD, 17th May 2007) and really enjoyed it.

    Here are my slides PDF Slides.

    My talk was Talk 6 and there's a linked blog discussion here: Talk 6 Blog.

    I've posted a short summary of my talk there, and I'll cross post here.

    The talk took the title of the WebCamp literally, and looked at issues of the "Emerging Mobile Internet".

    For me the Internet is the TCP/IP suite of protocols, that includes application layer stuff like http, but is based on the underlying architecture of packet switching and naming at lower layers. For me the biggest issue here is the broken architecture of the Internet itself where NAT forces services and applications to try and get around the issue of machines not have real publicly addressable identities (IP addresses), and where every packet is changed en route by middle boxes to the detriment of efficiency. My slides showed that we'll run out of centrally assigned IANA /8 blocks of IPv4 addresses in 2009/2010 and then regional registries will have problems fulfilling requests within another year or two from then. IPv6 solves the address shortage issue, and also opens up the Internet architecture to again allow any device to offer a service to another device (the end-to-end principle), allowing innovate p2p services.

    At the high service and application levels the main issues for me are: (i) how Internet telephony can be made to work without opening up telephony to spam (as email, blog comments, blog trackbacks, and all such are due to the open nature of identity on the Internet, and the low level of default/assumed security) and (ii) how the mobile web should ideally be designed to be the same as the real web, that there should just be one web, with different presentations on desktops and mobile phones, but the same back-end services.

    Update 2007-06-03 My slides have been published on slideshare.

    Geof Houston now predicts IPv4 IANA/8 exhaustion in December 2009

    IPv4 Address Report Geof Houston has updated his model predicting IPv4 address space exhaustion. Now the projected IANA Unallocated Address Pool Exhaustion date is 18-Dec-2009. Last month this prediction was 06-Jul-2011 (c.f. my earlier blog post).

    He notes:

    (Note: 8 May 2007) Frequent visitors to this page would see that the projected data of IANA unallocated pool exhaustion has moved by some months as of the 8th May. The reason for this change of the projection is the use of a different mathematical model as of this date. Previous reports used a best fit of an exponential model to the most recent 1000 days of data in order to generate the predictive model. As indicated in Figure 22 of this report, this exponential model now deviates from the recent data, and the predictive model is based on a quadratic equation.

    IPv4 Address Space Exhaustion

    This blog entry on the ICANN site shows some interesting maps of the assigned IPv4 address space and some links to discussions on IPv4 address space exhaustion: ICANN Blog: Blog Archive: Mapping the Internet, one node at a time

    I have recently noted to my work colleagues in the TSSG that Geof Houston's (of APNIC) predictions are now converging with Tony Hain's (of Cisco) predictions at around late 2010 - mid 2011 for the last IANA/8 to be allocated, that's less than 1 year divergence. This means that there is broad agreement on this prediction.

    Geof Houston's prediction is updated regularly. As of yesterday he predicts no IANA/8 left after 06-Jul-2011.

    UPDATE 2007-05-08 Geof's prediction revised to December 2009!

    Tony Hain's prediction, published in September 2005 in the Cisco IPv6 protocol Journal, and well worth a read both for the article itself and for the discussion printed at the end of the article. His predictions are summarised in these two statements:

    "So this view of the sustained trend in allocation growth rate suggests that the lifetime of the remaining central IPv4 pool is 4 years +/-1." [i.e. Sep 2009 +/-1]


    "The various projections in Figures 5 and 6 show different mathematical models applied to the same raw data. Depending on the model chosen, the nonlinear historical trends in Figure 6 covering the last 5- and 10-year data show that the remaining 64 /8s will be allocated somewhere between 2009 and 2016, with no change in policy or demand (though as discussed previously there are already reasons to err toward 5-year based nonlinear models)."

    His model graph is updated quarterly.

    In fact it is worth quote the concluding few sections of Ton Hain's original article in full as they address a number of other possible issues that may arise:

    "Reserved Space
    There are occasionally arguments that the 16 /8s reserved in the experimental space could be used. Although this is likely to be possible for some IP stack implementations, for others it is not. At a minimum, some quick tests show that Windows 95 through Windows 2003 Server systems consider that block to be a configuration error and refuse to accept it. The operational ability to restrict the space to a select stack implementation is limited, and the amount of space there does not really help even if deployment and operations were trivial. Assuming the sustained growth trend in allocations continues, by the time the remaining 64 /8s in the IANA pool are finished the rate would be approaching 3 /8 allocations per month, so the entirety of the old Class E space would amount to about 6 months of run rate.

    Reclaiming Allocations
    Another debate occasionally resurfaces about reclaiming some of the early allocations to further extend the lifetime of IPv4. Hopefully this article has shown that the ROI for that approach is going to be extremely low. Discussions around the Internet community show there is an expectation that it will take several years of substantive negotiation (in multiple court systems around the globe) to retrieve any /8s. Then following that effort and expense, the likelihood of even getting back more than a few /8 blocks is very low. Following the allocation growth trend, after several years of litigation the result is likely to be just a few months of additional resource added to the pool - and possibly not even a whole month. All this assumes IANA does not completely run out before getting any back, because running out would result in pentup demand that could immediately exhaust any returns.

    Network Address Translation (NAT) and CIDR did their jobs and bought the 10 years needed to get IPv6 standards and products developed. Now is the time to recognize the end to sustainable growth of the IPv4-based Internet has arrived and that it is time to move on. IPv6 is ready as the successor, so the gating issue is attitude. When CIOs make firm decisions to deploy IPv6, the process is fairly straightforward. Staff will need to be trained, management tools will need to be enhanced, routers and operating systems will need to be updated, and IPv6-enabled versions of applications will need to be deployed. All these steps will take time - in many cases multiple years. The point of this article has been to show that the recent consumption rates of IPv4 will not be sustainable from the central pool beyond this decade, so organizations would be wise to start the process of planning for an IPv6 deployment now. Those who delay may find that the IANA pool for IPv4 has run dry before they have completed their move to IPv6. Although that may not be a problem for most, organizations that need to acquire additional IPv4 space to continue growing during the transition could be out of luck."

    So it is clear to me that IPv4 addresses are running out, and IPv6 is the only viable alternative. Whilst the TSSG do engage in "post-IP" research, looking at potential alternatives, there is no question that IPv6 will need to be deployed to meet IPv4 exhaustion, and any post-IP research will require 10-15 years to be ready for deployment, and that's simply too late for IPv4 exhaustion.

    This is why I am Director of the Irish National IPv6 Centre and Chair of the Irish IPv6 Task Force and Ireland's representative on the European IPv6 Task Force and the world-wide IPv6 Forum. When we started the Irish National IPv6 Centre in September 2005 there were 64 IANA/8 blocks left, last month this was down to 47. The waiting game is over, it is time to start planning IPv6 deployment today.

    Network Neutrality

    Wendy M. Grossman argues, in an interesting way, that we have two network neutrality debates in parallel: net.wars: Double the networks, double the neutralities

    The upshot is that because the two markets - wireless phones and the Internet - have developed from opposite directions, we have two network neutrality debates, not one. The wonder is that it took us so long to notice.

    Umm, interesting, you could substitute two NGNs "next generation networks" for this and would read just as well.

    WIT TSSG SIP IPv6 Project

    One of my colleagues in the TSSG, Jonathan Brazil, has just posted a summary of his experiences getting client SIP software to work with IPv6 Jonathan Brazil's Weblog: IPv6 - How I got there.... Great that we got there, and great for him to share these details via his blog for us all to read!

    IMS (IP Multimedia Subsystem) is a big deal in modern telecommunications, and is a core (but not the only) part of the TSSG's approach to converged communications services. On principle we try to develop everything we do as dual stack IPv4/IPv6 to be really ready for the next generation internet. This project is one example of this approach in practice.

    Are We Slowly Losing Control of the Internet (Karl Auerbach)

    In this short article Are We Slowly Losing Control of the Internet? Karl Auerbach bemoans the lack of simple standards, as options proliferate, and standards bodies try and please all the stakeholders. A common problem. He sets his sights on SIP as an example of what can go wrong. Perhaps most interesting he links to a good set of slides From Barnstorming to Boeing - Transforming the Internet Into a Lifeline Utility that has speaker notes. Hey many this guy is trying to help out on my MSc (taught) module on SIP after all - though they're a bit high level. In any case I agree with the main message - we need to plan how to manage this stuff.

    A good analysis of the distribution of IPv4 and IPv6 AS (autonomous systems), prefixes and addresses across the world CAIDA : analysis : geopolitical : bgp2country. Interesting that IPv6 is still dominated by wealthier countries, but as there are so many addresses, they won't be able to hoard them; in contrast the USA dominates Ipv4 address allocations and has - it could be argued - hoarded them.

    In contrast it is very hard to get good quality telecommunications data for analysis, mainly for commercial and legal reasons the operators are reluctant to release, even "anonymized", data.

    Good science need good data, so it's good to see this type of Internet data being made available.

    IE TLD domain registration

    Michele Neylon comments on issues facing top level domain registrars IE Namespace: We Need Personal Domains!

    Circle ID says of him: "Michele Neylon is MD of an Irish hosting and domain registration company.
    He is also involved with the Irish Internet Association (http://www.iia.ie ) and the ISP Association or Ireland (http://www.ispai.ie ).
    He currently sits on the enum353 policy advisory board where he acts as the Irish Internet Association's representative."

    I have tended to avoid .ie domains myself (and for my work) as the process was too cumbersome, and paper-bound, and also more expensive than ".net",".org" or even ".com" if you could find a free name. Perhaps these initiatives in the IEDR will make it easier for us to use ".ie" for our domains in future... Good luck with it!

    I'll hold my fire on the iPhone hype to see how it all works out in practice. I'm a big Apple fan, and a MacBook Pro user, but I'm very happy with my Sony Ericsson P990i for now, and I'll decide whether to move to a new handset or not as the occasion arises. What is strangest for me is the move to using the finger as the pointing decice. On the P990i I use the stylus for writing letters as input, and I can do this very quickly, I cannot see the finger replacing the pen (whilst not as old as the finger, it certainly has a venerable history as a human interface tool) any time soon!

    Comments on EU Research Funding Policy

    It isn't often I read comments on EU research funding policy on the web, this post by Haydn Shaughnessy of "What Will You See Next?" has piqued my interest: Future of the Internet, it comments on an event in Brussels on 15th December Information Day.

    The idea of the EU Technology Platforms (EUTPs), such as NESSI and eMobility that are mentioned, and NEM, ARTEMIS and Photonics 21 that are not, is that industrial entities based in the EU (including multinationals with a base here), with a minor role for associated academic groups, can help to set part of the strategic research agenda (SRA) for future investment in research by the EU - the world's biggest publicly funded research programme. The Commission doesn't directly control these EUTPs, so if they fail to come up with a sensible research agenda, it is fault of the EU industrial sector for either not being able or not being willing to do this job!

    Of course, with respects to the next generation of the Internet, one problem for us in Europe is that the epicentre of the industrial strength of the existing software industry, the Internet and the Web lies in the USA, with perhaps SAP being the only EU success in modern software!

    Instead, in Europe we have a strong solutions provider marketplace with companies like Siemens and ATOS Origin (who are present in these EUTPs). It is argued that Siemens employ more software developers than anyone else in Europe.

    Of course, in contrast, the big EU success has been GSM and the mobile industry including the equipment vendors such as Ericsson, Nokia and Siemens and the operators (Telefonica, Vodafone, and so on). The EU Commission often argues that the research and development investment in earlier framework programmes (especially in ACTS in FP4) helped make GSM the success it is today.

    As these two worlds merge into the converged communications environment, where all these Internet, telephone and multimedia services run over TCP/IP (and I would argue should run over IPv6) it will be interesting to see how the EU research community engages with these challenges.

    As we speak the EU is launching the Framework 6 Programme in Helsinki (as Finland currently has the Presidency of the EU) at the IST Event 2006. The next 7 years of the research programme will have to deliver on some of the promises of convergence, of of European technological leadership to justify the investment in R&D that has been and will be made.

    As the Irish group with the most EU FP6 IST funding (more than any other university or company) the TSSG has a strong delegation at the IST Event, and is engaged in a number of the EUTPs, and is helping shape the strategic research agenda in other areas such as security (c.f. the recent invitation-only high level EU-US Security Summit hosted in Dublin organised by us on 15th and 16th November 2006). So we're certainly trying our best to make sure that the EU does get things right, and that Ireland plays a part in this.

    ITU Releases: World Information Society Report 2006

    You can download the whole report as a PDF or access it by chapter: World information Society Report 2006

    Strong gains have been achieved in digital opportunity around the world, according to a new report from the International Telecommunication Union (ITU). The World Information Society Report is part of ITU's contribution to the 2006 session of the UN Economic and Social Council (ECOSOC), which is meeting in Geneva from 3rd to 28th.
    The Asian economies of the Republic of Korea and Japan continue to lead in digital opportunity, due to their pioneering take-up of broadband and 3G mobile services. Nearly all Internet subscribers in the Republic of Korea are broadband subscribers, whilst Japan is the only market where Internet subscribers are most likely to access Internet over their mobile. Dramatic progress has been achieved by developing countries, however, which made the greatest progress in digital opportunity - notably India, where digital opportunity nearly doubled between 2001 and 2005, and China, which experienced remarkably strong gains in infrastructure. Different countries are following their own paths in telecommunication development, with some countries leveraging their investments in infrastructure more successfully than others.
    In response to the World Summit on the Information Society (WSIS) goals, the report tracks the changing dynamics driving the Information Society worldwide, with a new tool - the Digital Opportunity Index (DOI) - that evaluates the opportunity, infrastructure and utilization of Information and Communication Technologies (ICTs) for 180 economies worldwide. The Index monitors the mobile communications that promise to bridge the digital divide in many parts of the world, as well as more recent technologies such as broadband and mobile Internet access. The price of broadband continues to fall worldwide, by as much as twenty per cent a year over the last two years according to ITU's analysis, while broadband speeds continue to increase. These trends are not restricted to developed countries, however, with broadband now commercially available in 166 countries worldwide.
    As part of the ITU's work in follow-up to the WSIS, the report is addressed to policy-makers and regulators. It shows how this new Index can inform the policy-making process in the critical areas of the digital divide, universal access, gender, and the development of broadband networks. The Report gives practical examples of how the DOI can be used, and highlights projects around the world that are working to meet the commitments made at the WSIS.
    The DOI has been developed by a multi-stakeholder partnership (the Digital Opportunity Platform) comprising ITU, UNCTAD and the KADO (Korea Agency for Digital Opportunity and Promotion) and which is open to other partners. It will be reported annually in order to track progress in reaching the WSIS targets, and building a diverse and inclusive Information Society, by 2015.

    Rent elastic computing from Amazon

    Amazon seem to be blazing a trail with their flexible computing (Elastic Compute Cloud - Amazon EC2) and flexible storage (Simple Storage Service - Amazon S3) products that allow anyone to deploy scalable Internet services easily, see Jon Udell's experiences documented here Amazon.com's rent-a-grid | InfoWorld | Column | 2006-08-30 | By Jon Udell

    He notes this may not be the best option if you need a dedicated machine with continuous demand:

    As the blogosphere quickly noted, the EC2 rate of a dime per instance-hour works out to $72 per month for the equivalent of a 1.7Ghz Xeon CPU with 1.75GB of RAM and 160GB of local disk. And that doesn稚 include bandwidth, billed separately at the S3 rate of 20 cents per gigabyte. So for now, if you want to park one box on the Internet and leave it running indefinitely, better deals can be had from dedicated hosting providers. As the service痴 name suggests, though, if you need an elastic capability that can nimbly grow or shrink, EC2 is the only game in town.

    Other alternatives include 3tera.

    The Network Neutrality Debate

    The recent flurry of activity in the USA on legistlation to determine whether network operators can prioritise certain types of Internet traffic over others in order to use this ability to leverage funding for the service providers who use the Internet to deliver Internet-based services has raised amany interesting issues. The debate has revolved around the new term Network Neutrality. This article by By Robert X. Cringely
    PBS | I, Cringely . June 29, 2006 - If we build it they will come (subtitled "It's time to own our own last mile") is a thoughtful contribution to the debate. The argument is at a high level over whether the system of networking infrastructure ownership itself is wrong for the next generation of Internet-based services. This links to one of my hoby horses, the concept of the StockholmOpen community owned network infrastructure model (for wireless and broadband). It will be interesting to see how these models develop over the next twenty years.

    IPv6 Forum Roadmap & Vision

    The IPv6 Forum has released its IPv6 Forum Roadmap & Vision document.

    Ladid, Latif and Bound, Jim and Pouffary, Yanick and Rich, Yurie and Green, David (2006) IPv6 Forum Vision 2010 Roadmap. In: The IPv6 Forum World Congress, 21-22 February 2006, Las Vegas.

    This document was based on discussions at the IPv6 World Congress in February 2006, Las Vegas, and on subsequent discussions.

    The document combines a technical perspective and overview (drawing on the core expertise of the IETF members who specified the RFCs that make up IPv6, and related industrial and academic research expertise), and a business case overview. The report places these perspectives within the context of models predicting when IPv4 address shortage will start to happen, and when this shortage have a major impact on the Internet as we know it (e.g. Tony Hain's IANA IPv4 Pool Depletion Model Internet protocol Journal article and Updates to model).

    IPv6 Day: IPv6 Comes of Age

    From the IPv6 Portal

    Today 6Bone Operators and Users say bye to the experimental network which allowed, already some years ago, to turn IPv6 into the production space.

    With the occasion of this virtual celebration, we have a couple of quotes from two key people on this subject:

    • Bob Fink (6Bone Project): "After more than ten years of planning, development and experience with IPv6, with efforts from all around the world, it is gratifying for me to see the 6Bone phase-out on the 6th of June 2006, having served it's purpose to stimulate IPv6 deployment and experience, leaving IPv6 a healthy ongoing component of the future of the Internet!"
    • Brian Carpenter (IBM, co-author of multiple IPv6 RFCs and IETF chair): "It's very encouraging to see IPv6 moving forward both technically and commercially, with its address assignments now routinely managed by the same registries that look after the rapidly diminishing IPv4 address pool. I look forward to the day the Internet reaches ten billion active nodes with public addresses, which will only be possible with IPv6."

    Users can learn how to enable IPv6, enjoy free IPv6 production connectivity and use some trial services at the IPv6 Day web site (in several languages).

    Juniper try to define "IPv6 Capable"

    WebWire report WebWireョ | Juniper Networks Launches 'IPv6 Capable' Report to Aid Federal Agencies in Understanding Technical Requirements of IPv6 that Juniper have published a report to try and define what it means to "IPv6 Capable". Given that many contracts are trying to future proof new equipment purchases, this is a wise move, as there is lots of room for equivocation here (from: we will have an upgrade path... to: it is supported - but not what features are supported).
    Juniper Networks, Inc. (NASDAQ: JNPR) today announced the launch of its report, IPv6 Capable: A Guide for Federal Agencies, to provide technical guidance for the transition to IPv6 by June 2008, as mandated by the Office of Management and Budget (OMB). This report will assist federal agencies in understanding and meeting technical goals based on their unique requirements and missions, while achieving high-level objectives outlined by OMB.

    Wireless Networks for the Developing World

    Tim O'Reilly on Wireless Networks for the Developing World

    The need for wireless connectivity is increasing. This is especially true in developing countries that are lacking in infrastructure. Rob Flickenger, former O'Reilly editor, is currently publishing books to assist with this need. His first can be found at WNDW.net and is entitled “Wireless Networks for the Developing World”. It’s available as a free PDF (40K downloads so far). It leads its readers through the design and security of a network to building low cost hardware. Work on the book has continued on the site's wiki where the community has been adding case studies and links to other online wireless resources.
    His next book is being funded by an NGO. The book will be about bandwidth consumption. Commonly sysadmins in developing countries do not know how to manage their assets efficiently. They have satelite connections and they run their entire network through them. This book aims to teach them what to run locally and help them save on their bandwidth bills.

    Your Mobile Phone is Watching You

    Phil Windley on Phil Windley's Technometria | Your Cell Phone Is Watching You ...

    Your Cell Phone Is Watching You

    One of my favorite programs from last week was Nathan Eagle’s Where 2.0 presentation on using cell phones to predict user behavior. Using only publicly available data, Eagle was able to deduce relationships between pairs and groups of individuals.

    There are privacy concerns to be sure. Your cell provider already has much of this data. Every time two cell providers merge, what little protection we get from disparate carriers is broken down.

    What interested me most though it not the privacy concerns, but the potential to infer and enhance social interactions using the wearable computers each of us carries around everyday.

    What’s needed to make this not only more private, but also more useful is real user-centric identity that trasfers across carriers and domains. People often move past identity to get to the fun stuff, but it’s the identity infrastructure that makes it all useful and practical.

    US lags in IPv6 Adoption

    A Washington Times article on US IPv6 adoption: U.S. slow to switch to new Web protocol - Business - The Washington Times, America's Newspaper

    The federal government must move to the new Internet protocol by 2008, and the Defense Department started its transition in 2003. But since then, the U.S. has slipped behind many Asian and European nations in making the switch, said Rep. Thomas M. Davis III, Virginia Republican and chairman of the House Government Reform Committee.
    Of the 8,000 Internet service providers worldwide, about 10 percent offer IPv6, Mr. Ladid said. Consumers can get the necessary connections now in the U.S., but it takes hours to set up and only a few companies sell them.
    Consumers can expect to see IPv6 benefits in "three to four years, if we implement correctly," but that depends on who does it, Mr. Davis said. "If we don't, we'll be buying products from Europe and China."
    The next 24 months will be a "very interesting, chaotic period," said Marine Corps Lt. Col. James Bacchus, strategic planner in the office of the assistants to the chairman of the Joint Chiefs of Staff for National Guard and Reserve Matters. No one knows which will be first large program or user group to take advantage of IPv6, but he said the Defense Department will be first at doing IPv6 best.

    Glad to see the start of mainstream press coverage for the debate on IPv6 deployment.

    Analysis of Skype

    Here's a reference to an interesting analysis of the technology used in Skype, and a discussion of "Edge-connectivity" as a concept SATN.org: Comments from Bob Frankston, David Reed, Dan Bricklin, and others

    It is useful to be able to understand how Skype works in detail in order to trust the code. I'm glad to see that the authors noted that it is difficult to block Skype traffic.
    The more important result is to understand Skype's Edge-connectivity. It's an example of how communities can stay connected independent on the accidental properties of the Internet and the gatekeepers. Because the relationships are maintained at the edge mobility is fundamental. You don't need the network to do meshing when the applications maintain their own relationships. Meshing then becomes a low level technique for pooling routers rather than a way to make applications mobile.

    The Future Ends at the Firewall

    O'Reilly Radar > The Future Ends at the Firewall

    I like the catch phrase of this article blogged by Tom O'Reilly referring to this Financial Times article The Future Ends at the Firewall

    The idea is the enterprise networks are stifling innovation with restrictive internal security management. An interesting debate. One of the most powerful things about Internet technologies is the way they lower the cost on entry for new services, but if everyone has to tunnel through firewalls and NAT gateways to get them to work, it isn't so easy. One solution is to move towards IPv6 which obviates the need for NAT gateways to preserve scarce IPv3 address space. This may usher in a new era of distributed management rather than choke point firewalls, we'll see.

    Irish Broadband: An Embarassment

    Having just come back from eChallenges 2005 (Slovenia) the most embarassing thing for me as an Irish delegate is how far down the table of broadband penetration Ireland lies. It really does show us to be the laggards of Europe and not the leaders.

    "This time the survey comes courtesy of ECTA, the European association of alternative telecom service providers, which positioned Ireland 14th out of the 15 European Union Member States. Embarrassingly, the report shows that Ireland has been overtaken in terms of broadband penetration by some of the new EU member states, like Hungary, Slovenia and Lithuania."

    From: ElectricNews.net:News:Ireland gets poor marks for broadband

    This poor performance doesn't surprise me as I am more than willing to pay for ADSL but it still is not available in my town in rural Co. Waterford.

    Irish National IPv6 Centre Launch Event

    Waterford Institute of Technology hosted the launch of the Irish National IPv6 Centre on Friday 30th September 2005.

    This centre is a consortium led by the Telecommunications Software & Systems Group (TSSG) in Waterford Institute of Technology (WIT), with partners in the Hamilton Institute (NUI Maynooth), HEAnet (Ireland's national research network) and BT Ireland (with their links to the BT Exact research laboraties in Ipswich).

    The centre was designated by the Irish DCMNR (Department of the Communications, the Marine, and Natural Resources) and opened by Martin Cullen TD, Minister of Transport. The Director of WIT, Prof. Kieran Byrne, and the Chair of WIT's Governing Body, Redmond O'Donoghue welcomed the Minister. The Head of Research in WIT, Dr. Willie Donnelly gave a short address on the importance of the TSSG within the context of WIT's research strategy. As part of the programme of talks for the launch event Mario Campolargo, Head of Unit DG-INFSO F3 Research Infrastructures in the European Commission, gave a presentation via video-link from Brussels.

    Each of the partners gave a presentation: Mícheál Ó Foghlú (TSSG, WIT), Dr. David Malone (Hamilton Institute, NUI Maynooth), Mike Norris and David Wilson (HEAnet) and William McAuliffe (BT Ireland). In addition short presentations were given by a number of supporters of the initiative: Dr. Mark Keane (Science Foundation Ireland, who have funded the TSSG and the Hamilton Institute in ways that support the centre), Nick Hilliard (INEX) and Latif Ladid (President of the global IPv6 Forum).

    The afternoon included demonstrations of active research projects involving IPv6 in which the partners in the Irish National IPv6 Centre are engaged including Daidalos, and SEINIT.

    The Irish National IPv6 Centre is committed to continuing to research infrastructural and service-related issues linked to the use of the IPv6 protcol as the key element of the next generation Internet. In this, the centre will support the on-going mission of the Irish National IPv6 Task Force to encourage and lobby for the deployment of IPv6 in Ireland in the public and private sectors.

    Rebutting IPv6 Myths

    Twenty Myths and Truths About IPv6 and the US IPv6 Transition
    Sensible set of home truths about IPv6 from Alex Lightman.... in the form of rebuttals for 20 myths of IPv6 and the USA:

    1. Myth: There is no need for IPv6.

    2. Myth: IPv4 works well enough. Everything that can be done in v6 can be done with v4.

    3. Myth: The market will take care of IPv6, if IPv6 is useful.

    4. Myth: No, really, the market will take care of IPv6! The Dept. of Commerce says so!

    5. Myth: The U.S. federal government has a vision, mission, and a plan for IPv6.

    6. Myth: The Dept. of Defense will be implementing IPv6 by 2008, and the DoD invented the Internet, so it's going to happen just like last time around.

    7. Myth: Federal agencies are taking IPv6 into consideration already.

    8. Myth: Federal agencies don't need to know about IPv6 yet. It doesn't matter.

    9. Myth: Classified networks require air gap separation between them and non-classified networks, so if they aren't hardwired together, there shouldn't be a problem.

    10. Myth: OK, so what's the problem if hackers use IPv6 to access confidential or classified information? If no one has IPv6 plans, then I can't be held responsible.

    11. Myth: The U.S. is not behind Japan or other countries. All they've done is put IPv6 in some buildings, dorm rooms, and taxis. Big deal.

    12. Myth: No one is keeping track of who is leading in IPv6.

    13. Myth: The U.S. government doesn't have a good track record in leading technology

    14. Myth: IPv6 doesn't impact the economy or international trade in any significant way.

    15. Myth: US companies are always the leaders in technology.

    16. Myth: China is a third world country, and their use of IPv6 is irrelevant.

    17. Myth: If the U.S. federal government spends money on the Internet, it benefits everyone, and the U.S. doesn't get any special advantage, or return on investment.

    18. Myth: IPv6 doesn't impact the lives of ordinary people or "Joe Six Pack."

    19. Myth: IPv6 is already completed, so the U.S. government has nothing to say.

    20. Myth: IPv6 is boring. Even the name is boring, and hard to remember.

    I'm in Nice this week for IM 2005, a conference on Integrated Management that addresses the challenges in telecommunications network and service management, and looks forward to the challenges of converged management. The conference draws together a mixed academic and industrial audience, under the auspices of the IEEE Communications Society. The conference is co-located with the larger TeleManagement World sponsored by the TeleManagement Forum:
    "The TeleManagement Forum was founded in 1988 as the OSI/Network Management Forum with the goal of accelerating the availability of interoperable network management products. Founding members included AT&T and BT on the service provider side, and suppliers such as Northern Telecom and Hewlett-Packard on the equipment side. By early 1989 it had approved its first OSI/NM Forum Protocol Specification and by 1990 it had 85 members from 13 countries.
    The Forum has continued to adapt as the technological and business landscape has developed. Today, the TeleManagement Forum has more than 400 members, runs the industry痴 leading OSS/BSs Conference and Exposition, and its standards are being adopted by the UN body, the International Telecommunications Union (ITU).".

    Who invented the Internet?

    In this article Future of the Internet Ian Peter discusses the way that Internet history has been simplified into the triumph of Arpanet. He presents a more complex origin in which Arpanet does play a part.

    1. There are a number of valid claims to origins of the Internet.
    2. Although an original date and place might be obtainable for the first networked transmission that could be called an Internet, the result would need by definition to include more than one party or network, and is unlikely to be a satisfactory or useful conclusion.
    3. Not only US projects were involved in the beginnings of the Internet.
    4. Not only government funded US research programs were involved in the beginnings of the Internet.
    5. Not only telcos and the commercial sector were involved in the beginnings of the Internet.
    6. Neither Arpanet nor TCP/IP is present in all valid theories.

    Udell Argues that WS-* may be a combination of smart networks and smart nodes

    Jon Udell: Are smart networks always a dumb idea? In this short posting Udell challenges the traditional Internet-centric idea that Internet services imply smart machines and a dumb network (in contrast to traditional telecommunications networks with dumb terminals - phones - and an intelligent network).

    If Udell's hunch is right, this could mean that there is more going on in convergence than people thought. Don't forget that the telecommunications world was service-centric long before the Internet world. Maybe we still do have more to learn from each other.

    Udell was focused on the WS-* technologies. Moving the argument slightly, into another sphere where Udell is an elegant spokesperson for emerging technologies, I still like the metaphor that HTTP and SIP are both protocols with a very small set of primatives that potentially enable a huge diversity of useful interoperability.... I hope that SIP can do the same for computer-telephony as HTTP has done for distributed computing: revolutionise by lowering the barrier to entry for innovative new services. Personally I'm not so hung up on where the intelligence lies as long as we all enabled to do more interesting stuff more easily....

    Study: 2004 was 'turnaround' year for telecom industry

    InfoWorld: Study: 2004 was 'turnaround' year for telecom industry: February 01, 2005: By : NETWORKING : TELECOM This article on InfoWorld highlights what a lot of us are feeling, that things are on the up again for Telcos. I hope this leads to progress in convergence and some real penetration of value-added services into the Telcos' networks.

    Independent telecom analyst Jeff Kagan called the report good news for the telecom industry. "Telecom was growing until it hit a brick wall a few years ago," Kagan said in an e-mail. "By late 2004 it seemed obvious that telecom was getting hot again. I think 2004 was the turn-around year and 2005 will hit the ground running, both domestically and worldwide. Phone companies and wireless companies and cable companies are spending again and investing in their networks and getting ready for a new level of competition with each other."

    Walled Gardens and Network Effects

    Phil Windley's newly named Technometria blog has an interesting repost Walled Gardens and Network Effects.
    I originally linked to a posting by him in an earlier post on my own blog.


    "Walled garden" is the term that industry uses for online communities that capture users inside a Web that is anything but world-wide. The services inside the walled garden are the ones the service provider chooses and they almost always involve increased revenue for the service provider. When I was at Excite@Home, we had a project to build set-top boxes for our cable partners that included a cable modem, but kept subscribers who didn't sign on for broadband services inside a walled garden of for-pay services. The idea of walled gardens is far from dead. You live with them everyday on your cell phone. I hardly ever use the network services on my ATT cell phone because it's all about shoving ringtones and wallpaper down my throat rather than letting me easily get to the information that I need.

    In the Sept 16 issue of the Gillmor Gang (see www.gillmorgang.com), Ray Ozzie, of Notes and Groove fame, talks about how hard it is to create collaborative environments for portable devices. As noted by Ozzie, the operating systems on portable devices are too fractured and the interactions too limited to support network effects. By network effects, Ozzie is referring to the phenomenon that we frequently notice with social systems where the network of users grows geometrically because of user interaction. The applications being built for mobile devices are mostly used for personal productivity, not collaboration. The problem is that each mobile provider is trying to capture customers and create lock-in for their network instead of maximizing utility for users.

    Waterford MAN - e-net take over management

    Last Wed evening I went with a number of TSSG colleagues to a meeting about Waterford's MAN (Metropolitan Area Network). The official launch of the network itself was last September: Waterford MAN launch.

    This is an OAN (Open Access Network) owned by the public body (in this case Waterford Corporation), but leased out to competing operators. Where e-net come into it is as the neutral administrators of this network. It is part of regional and national network of such MANs. Service providers can pay standard rates to e-net to get rackspace in the co-location facility in each city/town. This then means that businesses connected can buy services from any of the service providers who have set up like this. The idea is that this reduces the infrastructural investment costs that each service provider has to put up before being able to start offering broadband to customers.

    The TSSG has been instrumental in laying the groundwork for these developments. Willie Donnelly, the Director of the TSSG, co-founded the SEISS (South East Information Society Strategy) initiative. The original SERPANT proposal, coming from SEISS, for funding from the Irish Department of Communications, the Marine and Natutal Resources (DCMNR) is what led to the investment in the regional WANs in the South East of Ireland: Clonmel, Dungarvan, Carlow, Kilkenny, Wexford and Waterford.

    As yet this the MAN service is primarily targetted at business and large public sector customers, rather than individual end users, but with new wireless standards with wide area coverage we could see the MANs being used as a core network for a much wider service offering to consumers.

    I have been very interested in the concept of open access networks for a few years now, both in terms of core optical networks, and in terms of wireless access networks. I have been very impressed by KTH (Technical Unioversity of Stockholm) and their involvment in Stockholm Open. This currently allows multiple operators to share both a core optical network and a WiFi access network in Stockhom and its suburbs (such as Kista where KTH and Ericsson are based). I hope that the MANs can deviver a pan-Irish open access network based on on these same principles.

    Switch over to IPv6 Day proposed

    This article Thoughts on IPv6 Day (By James Seng) discusses the proposal to have a national IPv6 Flag Day where all Internet machines switch over to mandated support of IPv6. It is a good summary of the arguments of why this is not such a good idea just now. However, James is still advocating the deployment of IPv6 especially to enable p2p end-to-end applications and services. If we can demonstrate a certain level of IPv6 penetration, and good hardware support in routers, the switch over could be closer than we think.

    Convergence: BT and Deutsche Telekom

    In an interesting article on InfoWorld Telcos' convergence strategies diverge Peter Sayer argues that BT has more flexibility in their approach as they do not have a mobile arm to support, and this may lead to innovative new services. He describes the idea of a mobile handset that can make calls via a wireline connection in preference to GSM (using bluetooth to create a local network) and thus save the customer money. They call this a "Bluephone".

    Network services and walled gardens

    On Phil Windley's Enterprise Computing Weblog he has a positing talking about Walled Gardens vs. Networked Effects
    . This neatly summarises the problems relating to trying to limit your customers on a network to the services that you have direct control over (wall garden); telecommunications services are usually seen as being in the category. This is contrasted with open networks where it is easy for anyone to offer services over the network; the Internet and the Web are usually seen as being like this. He concludes that many broadband networks are actually inbetween, where it is easy to consume services, but not easy to create them yourself.

    Siemens merges Enterprise Networking and Mobile Telephony divisions

    InfoWorld reports that: InfoWorld: Siemens launches new unit to focus on end-to-end systems : October 01, 2004: By : NETWORKING : TELECOM. They had previously split these divisions up in order to allow for focus, now they've decided there's more milage in combining them. This is a good metaphor for the so-called "convergence" that we've been promised where traditional telecommunications and Internet technologies merge, enabling a the mobile phone as one of the new platforms for this convergence. The new unit is called "Siemens Communications Group" and it merges the previous: "Information and Communication Networks (ICN)" and "Information and Communication Mobile (ICM)" units.

    Siemens are now one of the largest software companies in Europe, despite traditionally having had a very hardware/engineering focused reputation. They started as a telegraph company in the 19th century, and built the world's first electric railway. They are proud of their long history of excellence in engineering, and rightly so, see their corporate website Siemens' history for full details with images.
    Siemens have had a huge influence in Ireland because they won the contract to construct the Shannon hydroelectric power plant, the first major project in the independent Irish Free State.
    Siemens are very active in research networks, including telecommunications, and the TSSG work with them on a number of EU funded projects.

    UN ICT Task Force publishes "Internet Governance: A Grand Collaboration"

    This CircleID posting Fifth Publication of the UN ICT Task Force Series links to the UN ICT Task Force publication Internet Governance: A Grand Collaboration (this page has a link to the PDF itself). This is good source material for grounded debate on issues like the digital divide and other issues about the use of Internet throughout the world.

    QoS for IPv4 and IPv6

    The TSSG has been involved in a number of projects that relate to Quality of Service (QoS) for IP networks (both IPv4 and IPv6). The EU FP5 IST Intermon project focused on inter-domain monitoring of QoS. In fact, our contribution to this project was mainly in the software for the measurement and monitoring, and the visualiation of the results. The Irish TSR Strand III funded Converge project looked at QoS, security and accounting for IP networks.

    One of the research students on the second of these projects, Jesse Kielthy, published an overview of our approach An initial investigation into QoS provisioning in a DiffServ Network.
    It is interesting to see that other research groups have cited this paper as part of the context for QoS in IP e.g. Quality of Service Aspects in an IPv6 Domain (Bouras, Gkamas, Primpas, Stamos) of Research Academic Computer Technology Institute, Patras, Greece.

    WiFi access points in light fittings?


    An interesting posting on O'Reilly's website The NoCat Night Light
    How many cats does it take to screw in a light bulb?
    shows how it is possible to fit a WiFi access piint into a light fitting and use the powerline for data and power. Though this was posted last May, I only recently noted it.

    IPv6 gateway

    Shane Dempsey (of the TSSG) recently pointed out to me that you can now access many IPv4 web sites (e.g. Slashdot over IPv6) over IPv6 by using this SixXS IPv6 to IPv4 Website Gateway. The website servers need to not already be IPv6 enabled, and the web clients need to be IPv6 capable.

    Projection Keyboards


    This is an overview article on the current state of Projection Keyboards. It describes four products, gives links to their websites, and describes the companies and lists patents. All very interesting.
