my second FCC TAC meeting, and its IPv6 promise

Saturday, April 30th, 2011 by kc

I recently remotely attended my second meeting of the FCC’s Technological Advisory Council (slides but no video archives). The chairs of four working groups created at the first TAC meeting (Critical Transitions; IPv6; Broadband Infrastructure Deployment; and Sharing Opportunities) presented their interim results. The FCC then issued a set of “TAC recommendations” (which the TAC never saw); it is mostly a wish list from industry to the FCC. Ironically, IPv6 did not appear anywhere in the recommendations, despite being the most popular topic at the first TAC meeting last November, and despite us running out of IPv4 addresses since the last TAC meeting. But the TAC’s IPv6 WG did commit to (on slide 53) delivering a report by November 2011 on what the FCC could or should do to help promote IPv6 deployment. Specifically, the WG has the following charter:

CAIDA’s IPv6 measurement and analysis activities

Friday, April 29th, 2011 by kc

In pursuit of more rigorous data on IPv6 deployment, CAIDA has undertaken four IPv6 measurement and analysis exercises: address allocation data; traceroute-based topology; DNS queries from root servers; and a global survey of network operators in 2008.

Data on current status of IPv6 deployment

Thursday, April 28th, 2011 by kc

[Last month, I remotely attended the second meeting of the FCC’s current Technical Advisory Committee (TAC), where chairs of several working groups set up at the first meeting (in November) reported on their progress and plans. I’m a member of the FCC TAC’s IPv6 working group, (more on this soon), and so far have been asked to answer two questions I’ve been thinking about for a couple of years: what data do we have to gauge IPv6 deployment by Internet service providers, and what data do we need? Last November I addressed the first question in a (still pending) NSF proposal to measure IPv6 deployment, with the following text. I’ll post some updates shortly.]

annotated bibliography of IP geolocation papers

Saturday, April 23rd, 2011 by kc

Many applications require the association of Internet numbering resources with an accurate geographic label at some granularity. For some applications, knowing the country of origin might be sufficient; for others a more precise indication at state, city or zip code granularity, or even a specific latitude/longitude is needed.

However, which method(s) work best? Which database sources and services are most reliable, at what geographic resolutions? If a data source provides the geographic location of the owner of an IP address, is this location the same as the location where the device is actually broadcasting and receiving packets? And, if different, can the difference be quantified?

Thoughts on Internet2/UCAN business models

Friday, April 15th, 2011 by kc

This month Internet2’s new UCAN project issued a call for white papers on how they could use their $65M BTOP grant in operationally sustainable ways, i.e., so the infrastructure they build will have a chance of surviving when the federal stimulus project money runs out.

We held a relevant workshop 5 years ago, part of which was published in CommLaw the following year. I’ve also written several other essays on related issues:
