One way to determine the denseness of the Internet, or its "interconnectedness", is to look at the path length between Autonomous Systems (ASes). The "shortest AS path" is a route selection rule in the Border Gateway Protocol (BGP) that means traffic from one AS will chose the path with the least number of ASes to get to the receiving AS. With IPv6 being deployed in parts of the Internet, we looked at the AS path length to see if the IPv6 portion of the Internet is more or less interconnected than the IPv4 Internet. more
Contributing to international telecommunications standards, not in the IETF but in a more august and imposing body, the ITU-T, part of the United Nations, was quite an experience. Still called CCITT in those days, it was formal and solemn; everybody was part of and sat with their national delegation, countries were aligned in alphabetical order; nobody spoke out of turn, every word was simultaneously translated in the three official languages of the time and we wore suit and tie. more
Open Source (OS) Management and Orchestrations (MANO) is a European Telecommunications Standards Institute (ETSI) initiative that aims to develop a Network Function Virtualization (NFV) MANO software stack, aligned with ETSI NFV. The main goal of MANO is to simplify the onboarding of virtual network components in telco cloud data centers. The initiative has gained impressive momentum among leading Communication Service Providers (CSPs) around the world as part of their NFV programs. more
IPv6 adoption continues to gain ground at a slow pace. This is to be expected. The complications associated with hardware and software upgrades, as well as the lack of reachable content, means that IPv4 is still king of the hill. To me, this situation seems to mirror one a few years back with web browsers. Sometime around the turn of the century, Internet Explorer became the dominant browser. Riding on a 90% market share for Windows, the incumbent - Netscape Navigator - did not stand a chance. However, with it came a dark age for web developers. more
ISOTF Critical Internet Infrastructure WG is now open to public participation. The group holds top experts on internet technology, critical infrastructure, and internet governance, from around the globe. Together, we discuss definitions, problems, challenges and solutions in securing and assuring the reliability of the global internet infrastructure, which is critical infrastructure for a growing number of nations, corporations and indeed, individuals -- world wide. more
On Feb. 25, 2011, the National Telecommunications and Information Administration released the following request for comments concerning the USG's contract for the IANA function. As indicated, the USG's contract for the IANA function with ICANN expires later this year. Interested parties can file comments with NTIA by March 31, 2011. more
We saw it in San Jose, then in Taipei and in Philadelphia and now it is about to happen in Denver Colorado! Yes, the IPv6 hour is about to occur a fourth and even a fifth time! The upcoming ARIN XXI will have a pre-game and a main event IPv6 hour with technical staff to assist the neophytes on their first dive into the IPv6 only world... In the meantime in the Geneva Auto show, impact of IPv6 on ITS (Intelligent Transport Systems/Services) was a topic on its own with a revealing and well timed presentation by Thierry Ernst of Inria, the French Institute of Research in Informatics and Automation. more
Over the last couple of months, the enterprise computing space seems to have started a shift from private cloud paradigm into the hybrid cloud model. That makes sense, because the hybrid cloud allows companies to forgo the capital and the operating expenses associated with private clouds, in exchange for a pay-as-you-go model where you can just sit back and consume the business applications. more
At the IGF2010 in Vilnius, two folk are floating a trial balloon about separating the allocation function from the registry services function. Currently, these functions are seen as indivisible by the Internet addressing community. In other words, one gets an allocation or assignment from a RIR and the RIR adds the assignment to their database... The question being asked is "Is it time for a split between allocation and services for Internet number resources as was the case for domain name resources?" My answer is no more
Often when looking at IPv6 deployment statistics, the size of the organisation or the network is not taken into account. In this article, we look at IPv6 deployment of Local Internet Registries (LIRs) per country in correlation to the size of the LIR. When looking at IPv6 deployment at the LIR level, we can look at the following two metrics... more
In observance of World IPv6 Day being held today, Earl Zmijewski of Renesys takes a closer look at the state of the IPv6 today. Zmijewski writes: "Today is World IPv6 Day, a day when major content providers have agreed to furnish service over IPv6 for a 24-hour test period. Hopefully, you didn't notice anything different about your Internet experience today, but providers will have gained valuable experience with the technology and any technical hurdles that remain to be overcome..." more
An interesting new paper from the Naval Postgraduate School describes what appears to be an interesting new twist on spam filtering, looking at the characteristics of the TCP session through which the mail is delivered. They observe that bots typically live on cable or DSL connections with slow congested upstreams. ... This paper tries to see whether it would be practical to use that info to manage spam in real time. more
Unless you've been living under a rock, you've doubtless seen reports that the supply of IPv4 addresses is running out. Earlier this month IANA, the master allocation authority, handed out the last so-called /8, a large chunk of 16 million addresses, to one of the regional address registries... Then what? The conventional wisdom is that everyone needs to support IPv6, a mostly compatible upgrade to IPv4 with much larger addresses, by the time the v4 space runs out. But I'm not so sure, particularly for e-mail. more
No more "test flights" ... 2012 is the year that IPv6 gets permanently deployed! That is the message of "World IPv6 Launch," announced today by the Internet Society, Google, Facebook, Cisco, Microsoft, Comcast, AT&T, Time Warner Cable and a whole host of other companies. While last year's successful World IPv6 Day was all about testing how your site or service worked with IPv6, this year's World IPv6 Launch is about enabling IPv6 permanently as of June 6, 2012 (or earlier). more
The theme of the 40th International Institute of Communications (IIC) conference in Montreal this week was "Wrestling with unpredictability in Global Communications". The panel I had the pleasure to be part of was under the motto : "Broadband futures". One of the questions addressed to me : Should we be concerned about a shortage of IP addresses as more people use broadband networks for more things? more
