As a follow-up to the recent press flurry about Dima’s routing research, Voice of San Diego interviewed us for several hours last week, and no doubt spent twice that time focused on trying to get a complex story mostly right. Hyperbolic headlines notwithstanding, the journalist who interviewed us, David Washburn, did an outstanding job of fact-checking and making sure he accurately represented our views. If this is the future of journalism, I’m not the least bit worried about the death of 20th century journalism models. The real fourth estate is in good hands.
I’ve written before about the growing consensus among experts that the Internet’s underlying communications routing algorithms are fundamentally unscalable, so I am delighted to have CAIDA’s routing research group led by Dima Krioukov achieve some fundamental routing research results worth extensive media coverage. We have not solved the Internet’s routing scalability problem, but these recent discoveries will help that cause.
i gave a (faster, less understandable) version of this talk (pdf or slides+audio quicktime) at the October 2008 ARIN meeting in Los Angeles (original October version) and again to ISOC’s advisory council meeting in November. motivation: the end of the current addressing architecture, with scant understanding of how to retain all its positive features in the face of inevitable change. a topic i worry about more each year.

#9: The news is not all bad: there is a reason everyone wants to be connected to all the world’s knowledge — as well as each other — besides its status as the most powerful complex system ever created by man. The Internet’s practical promise for individual freedom, democratic engagement, and economic empowerment, is also unparalleled. This promise is sufficient inspiration for an open, technically literate conversation about how to invest in technologies and policies to support articulated social objectives.
#6: While the looming problems of the Internet indicate the need for a closer objective look, a growing number of segments of society have network measurement access to, and use, private network information on individuals for purposes we might not approve of if we knew how the data was being used.
i get this question a lot:
at the current churn rate/ratio, at what size does the
FIB need to be before it will not converge? (also sometimes pronounced ‘when will the current Internet routing architecture break?’)
a good question, has been asked many times, and afaik no one has provided any empirically grounded answer.
a few realities hinder our ability to answer this question.
