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.

PHP, JavaScript, Ruby, Perl, Python, and Tcl Today: The State of the Scripting Universe
Lynn Greiner discusses the use of scripting languages in mainstream applications development PHP, JavaScript, Ruby, Perl, Python, and Tcl Today: The State of the Scripting Universe - CIO.com - Business Technology Leadership. She refers back to an article she wrote in March 2005 on the same topic, and notes the much deeper penetration of scripting as a valid development tool today in 2008.
In the TSSG we have been firmly behind scripting languages as a vital part of any developers toolbox for many years. You may know that I published some books on Perl back in 1996 (e.g. Perl 5 Quick Reference (QUE)), and our team of developers and researchers have expertise in all of these languages, particularly JavaScript (ECMAScript), Ruby, Perl, Python and PHP. In particular one of our spin-out companies, FeedHenry, is based on creating a publicly hosted widget framework that promotes ease of creating of new services using lightweight scripting approaches.
Perhaps the best cited article on the advantages of scripting is John K. Ousterhout's "Scripting: Higher Level Programming for the 21st Century", published in IEEE Computer in March 1998. John, the author of the popular scripting language Tcl (pronounced "tickle"), pretty much lays out the case for scripting languages. The major developments since then have been the creation of new scripting languages with special usefulness for certain domains, and a maturity in the tools that help developers use scripting languages, and test and debug their scripts/programs.
A recent Forrester report "The Forrester Wave: Dynamic Programming Languages, Q3 2007" underlines the case for dynamic languages, focusing on Python, PHP and Perl.
The popular acronym for open source development platform LAMP comprises four elements:
- (L)inux (perhaps more properly termed GNU Linux made up of both the Linux operating system and the, many GNU, open source tools such as gcc that enable it);
- (A)pache open source web servers, note that Apache has been the leading web server in the world since 1996;
- (M)ySQL/PostgreSQL open source relational databases;
- (P)erl/PHP/Python/Ruby/... open source scripting languages;
The O'Reilly ONLamp.com site has a great range of materials on the various elements of this platform, and O'Reilly publish the leading books on each topic (e.g. Larry Wall, Tom Christiansen, and Jon Orwant's book Programming Perl (3rd Edition July 2000), known as the Camel Book because of its cover).

Google Estimate Over 1 Trillion Web Pages
Thanks to CircleID: Google Says Its Counting Over 1 Trillion Unique Pages on the Web?
"We've known it for a long time: the web is big. The first Google index in 1998 already had 26 million pages, and by 2000 the Google index reached the one billion mark. Over the last eight years, we've seen a lot of big numbers about how much content is really out there. Recently, even our search engineers stopped in awe about just how big the web is these days—when our systems that process links on the web to find new content hit a milestone: 1 trillion (as in 1,000,000,000,000) unique URLs on the web at once!"
It has been noted however that Google does not index all 1 Trillion web pages (see Michael Arrington)

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.

Camino-Waterford (May 2008)
Over the past two weeks I have travelled on the Camino Santiago (the way of St James) from Waterford to Santiago de Compostela, in Galicia, Spain. The route involved sailing on board the Jeanie Johnston (a replica 19th century wooden hulled sailing ship --- as close to medieval as we could get) from Waterford quay, out of the Waterford estuary, and the southwards past the Scilly Isles and across the Bay of Biscay to A Coruña on the north coast of Galicia; this was a journey of 4 days. The next section was on foot from A Coruña to Santiago de Compostela over 3 days. Finally we spent a few days in Santiago before flying back a more conventional twenty first century route to Dublin airport.
The journey was a recreation of the pilgrimage taken by a previous Mayor of Waterford City in 1473 and 1483, James Rice. This route was known in Medieval times as the "English Way", which was an alternative to the more famous land routes to Santiago such as the French routes that cross the Pyrenees and converge near Pamplona, or the internal Iberian (Spanish and Portuguese) routes coming from the south.
I have posted three sets of public photographs (as yet undocumented) on the Flickr photo sharing site, and I've made this available to everyone so that the people I travelled with can have easy access to them:
- Camino-Waterford Preamble (a small number of photographs taken on my camera phone during and after the ceremony in Christ Church Cathedral where Mary O'Halloran, the Mayor of Waterford, sent us on our way)
- Camino-Waterford Voyage (photographs taken with my Cannon 400D SLR with a Sigma 30mm F1.4 EX DC prime lens)
- Camino-Waterford Walk (photographs taken with my Cannon 400D SLR with a Sigma 30mm F1.4 EX DC prime lens)
I found the camino to a be a fantastic experience, particularly because of the people who we travelled with on the ship, and on foot. So a big thanks to my fellow pilgrims: Eamonn, John (of the shell), Jackie, Nina, Mary, Anne, Paddy, Pat, Jim, Oliver, Brian, Aidan and Tim; a big thanks to our fellow travellers on the ship: Sean, John, Pat, Maeve, Coleman, Stephen and Steve; a big thanks to the captain, officers and crew of the Jeanie Johnston (the captain, Luca, Paul, Daithi, , Quentin, Jim, Charlie, Suzie, Earl, Karen, Pat and Johnnie). The trip was organised by the Waterford Museum of Treasures, who placed this article (worth reading for some historical background on James Rice who made the pilgrimage in 1473 and 1483) in the local newspaper the Munster Express; so a special thanks to Eamonn and Donnchadh for making it all possible.

TSSG spin-out Zolk C wins prestigious museums award
In London on Wednesday 7th May 2008 the National Trust for Scotland was presented with an a Museums & Heritage Award (full list of awards) for "Use of Technology" in its Culloden site. This recognised the innovative use of technology, a GPS PDA system that delivers an integrated multimedia audio, video and text guide to visitors to the Culloden Battlefield site near Inverness in Scotland. This solution was developed by the TSSG spin-out joint venture company Zolk C together with content management experts.
Edited Wikipedia entry on Battle of Culloden
The Battle of Culloden (Scotts Gaelic: Blàr Chùil Lodair--most of the Highlanders would have spoken Scotts Gaelic), 16 April 1746, was the final clash between the Jacobites and the British Government in the 1745 Jacobite Rising. Culloden brought the Jacobite cause--to restore the House of Stuart to the throne of the Kingdom of Great Britain--to a decisive defeat.
The Jacobites--the majority of them Highland Scots, although containing significant numbers of Lowland forces--supported the claim of James Francis Edward Stuart (aka "The Old Pretender") to the throne; the government army, under the Duke of Cumberland, younger son of the Hanoverian sovereign, King George II, supported his father's cause. It too included significant numbers of Highland Scots, as well as Scottish Lowlanders and some English troops.
The aftermath of the battle was brutal and earned the victorious general the name "Butcher" Cumberland. Charles Edward Stuart eventually left Britain and went to Rome, never to attempt to take the throne again. Civil penalties were also severe. New laws attacked the Highlanders' clan system, and Highland dress was outlawed.
The picture shows myself, Paul Savage and Eamonn de Leastar, the TSSG members who were present at the award ceremony. No blood was spilled, though kilts were in evidence. A big thank you to the full team who made the award possible, including all those in the TSSG who helped.

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 spin-out creates location-aware interactive battlefield guide: Culloden Battlefield (Scotland)
The latest spin-out from the TSSG is called Zolk C Ltd., which recently launched an innovative new wireless tourism service for the Culloden Battlefield in Scotland (see quote below from the Sunday Telegraph, 24th February 2008).
It was all a long time ago, but the voices and images conjured by the new time machine at Culloden linger hauntingly in the memory.
On April 16th 2008, the National Trust for Scotland has organised the Grand Opening of the new Culloden Battlefield centre and exhibition. This will also include the new Zolk C service 'The Culloden Battlefield Guide'. Led by Paul Savage, a number of TSSG staff are attending this event.
The Culloden Battlefield Guide.
The innovative Battlefield Guide developed by Zolk C Ltd is the world's first GPS triggered electronic guide in use in tourism and heritage sites. With specially created audio, video and supporting illustrations (including key content from the BBC), the multimedia content is triggered automatically as visitors explore Culloden Moor, at their own pace, allowing them to understand and appreciate better what actually happened on 16th April, 1746.
Visitors to the exhibition at the new STG 9million Culloden centre can enhance their experience by walking the Moor with the Battlefield Guide. They will receive unobtrusive, location specific multimedia content while they soak up the atmosphere of the battle in situ. Initially in English and Gaelic the guide in time will be available in a range of languages from Spanish to Japanese and will be offered to all those visiting the moor.
Why use satellite technology? A key objective of the Culloden project was that the battlefield site should be restored, as close as possible, to that seen by the forces on that fateful day in April 1746. More traditional techniques such as interpretative panels or markers were not felt to be in keeping with the sanctity of the Moor as a war grave. As well as the multimedia content that is automatically triggered, addition information is available on a menu that changes depending on the visitor's position on the battlefield, allowing them to gain a more complete understanding of the events of 16 April, 1746.
Who is Zolk C?
Zolk C is a new venture based in Waterford, Ireland and Inverness, Scotland. Its remit is to create and operate technology solutions that enable interpreters to deliver a better, more effective user experience at tourism and heritage centres internationally. Zolk C provides full project lifecycle including design, development and management of interpretive solutions. The company is a joint venture between the Telecommunications Software and Systems Group (TSSG) of the Waterford Institute of Technology (WIT), who specialise in the research and design of pervasive, mobile technologies and of Zolk Ltd, an Inverness based company specialising in the design, deployment and management of on-line services. The Zolk portfolio includes Learning Works, Careers Scotland and UHI Millennium Institute. Zolk C has used their combined expertise to design, develop, deploy and manage the Battlefield Guide for the National Trust of Scotland (NTS).

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.
Are Native Mobile Applications Dead?
There's been an interesting discussion on the internal TSSG technical discussion list in recent days spurred by this provocative post from Michael Mace, an ex Palm employee: Mobile Opportunity: Mobile applications, RIP. His basic thesis is that it is so painful trying to develop for so many hardware platforms (that currently make up the mobile handset market) that developers will inevitably be drawn towards mobile web applications instead, even though this certainly has its own problems. He claims the business model for mobile developers of native applications is so flawed that the web-based approach will inevitably win out. It is an attractive thesis and one that definitely appeals to me.
To see some of the other on-line contributions to this debate:
- 3 Million Platforms (Elia Freedman, CEO of Infinity Softworks - posted in October 2007 - the comments point out that Symbian is actually composed a number of incompatible platforms including various versions of S60 and UIQ)
- Mobile Applications are dead (Stefan - Feb 2008) with a nice tombstone graphic
- What's all that other software for? (Peter Harbeson Feb 2008) explains how much functionality there is already available via the web on mobile smartphones
Unlike many of my colleagues I have such to a UIQ3 phone, the Sony Ericsson P1i (others seem to have Nokia N95 or iPhones), and even with its limited web browsing capabilities (Opera 2.3.08) it is a really useful tool. The native applications I use are: voice calls and SMS, camera, PIM (contacts, notes, calendar - though I sync with Google Calendar), and a very useful SSH client. In an emergency I use email (but it's very slow to sync with my IMAP server that has hundreds of folders), being able to send email is definitely useful. I use the mini-qwerty-keyboard and the touch-sensitive screen with a stylus for hand writing recognition about equally. Ironically I really like the built-in FM radio and use this more frequently than the MP3 player - which I do use for podcasts and music using a 4Gig card for external storage. If the bowser were more robust I would definitely use it even more.

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.

Internet prediced to reach zettabyte (annual US traffic)

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.

IETF NSIS
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.
