With measurement networks rapidly evolving up to hundreds of nodes, it becomes more and more challenging to extract useful visualisations from tons of collected data. At the same time, geographical information related to Internet measurements (either known or inferred with state-of-the-art techniques) can be exploited to build tools based on geography as a common knowledge base. We wanted to develop a tool to visualise different classes of geographically annotated Internet data, e.g., topology, address allocation, DNS and economical data. more
Tuesday June 29th at the Cisco Live Conference Las Vegas, John Chambers announced their newest product, the Cius tablet aimed at the enterprise market and positioned as a mobility product. That very same day a two hour IPv6 deployment panel, moderated by Cisco's Alain Fiocco, featured Google, Microsoft, Comcast and Tata Communications in front of a room filled to near capacity. The nature of the audience was interesting. Compared to previous years, when asked about their affiliation, the number of hands raised for the category 'enterprise' was significantly higher. more
Starting last week there have been a number of sensational headlines about IPv6 user adoption using adjectives and phrases like, "explodes", "skyrocketing" and "conquering the world". Nice to hear for sure but what does that mean to vendors of IPv6 gear or anyone else studying the market? more
On behalf of the Federal CIO Council, US Office of Management and Budget (OMB) announced today the release of the "Planning Guide/Roadmap toward IPv6 Adoption within the US Government". This document defines the Federal Government's Internet Protocol version (IPv6) direction, building upon requirements set forth in OMB Memorandum 05-22. It was developed by the CIO Council's IPv6 Working Group, in partnership with the American Council on Technology / Industry Advisory Committee, in consultation with and review by the Federal CIO community. more
When I see glib talk about the inevitable transition to IPv6 or DNSSEC, I have to wonder what industry people think they are working in. Let me give an example that has nothing to do with networking: storage capacity. Now if there is one constant that everyone in the computing industry can agree on it is that they expect storage media capacity to increase. more
Some think IPv6 with its myriad addresses will accelerate the evolution of a hyperconnected world. But could a world where everything and everybody is sensed, monitored, located, to augment our quasi real-time interaction with the world outside our little selves, lead to total dependency, if not to gradual stupidity of the human race? Not surprisingly, a favourite topic for (late night) Internet Conference bar discussions... more
We tend to make a number of assumptions about the Internet, and sometimes these assumptions don't always stand up to critical analysis. We were perhaps 'trained' by the claims of the telephone service to believe that these communications networks supported a model of universal connectivity. Any telephone handset could establish a call with any other telephone handset was the underlying model of a ubiquitous telephone service, and we've carried that assumption into our perception of the Internet. On the Internet anyone can communicate with anyone else - right? more
The Internet Routing Registry (IRR) is a globally distributed routing information database that consists of several databases run by various organisations. Network operators use the IRR to publish their routing policies and routing announcements in a way that allows other network operators to make use of the data. In addition to making Internet topology visible, the IRR is used by network operators to look up peering agreements, determine optimal policies and to configure their routers. more
Is the global, open Internet moving away from a network of networks that is universally accessible to a series of networks fragmented along policy, technical or economic lines? As some governments pass laws related to data localization and restriction of cross-border data flows, what will the impact be? What about the increasing use of DNS and content filtering? What other factors have the potential for causing fragmentation? more
Comcast is now the first large ISP in North America to start deploying IPv6. According to the company, this initial phase will support certain types of directly connected customer premises equipment (CPE), where a single computer is connected directly to a cable modem. "Subsequent phases in 2011 and 2012 will support home gateway devices and variable length prefixes." more
With reference to IPv6, probably most end users do not have any sense of it. The mainstream condition in the industry is that network carriers and content/service providers stick to their own arguments. Carriers consider lack of IPv6 content and service as the reason demand for IPv6 from the users is very low. The content and service providers believe that users cannot have access to content and service through IPv6 and thus carriers should provide the service in the background. more
The Internet Architecture Board's (IAB) chair, Olaf Kolkman, asked the members of the IAB to provide a statement paper each on what they believe the current most pressing issues in terms of Internet architecture are... I have thought about this for the past few days, and realised that it's hard to come up with overarching issues and even harder to come up with issues, where the IAB actually could make a difference. But I came with up with two issues. more
Within every organization a chosen few are tasked with introducing IPv6 into their networks, outward facing services or applications. But who are they? We know them as Network Engineers, System Administrators and Software Developers but are they one trick ponies spending all their time in layer 3? more
The Malaysian government is poised to fully adopt the Internet Protocol version 6 or IPv6 by the end of next year and may emerge as the first government in the world to achieve full IPv6 compliance, Deputy Information Communication and Culture Minister Datuk Joseph Salang said. According to the report several government agencies have already adopted IPv6 and several others are in the process of shifting from IPv4. more
By now you might have read the news "How 'Gangnam Style' Broke YouTube?" What happened is that a YouTube video named 'Gangnam Style' by a South Korean singer Park Jae-sang, known by his stage name PSY, has been viewed so many times that it broke YouTube's view counter. YouTube's view counter is built on a 32-bit integer, which provides a view-tracking capability of nearly 2.15 billion views. more
