Jim Cowie, Renesys Corporation

Jim Cowie is the co-founder and Chief Technology Officer of Renesys Corporation. Although best known to the NANOG community for his work on BGP routing dynamics and analysis of Internet transit markets, Jim's research roots are actually in high performance computing, parallel language compilation, and network modeling and simulation. When the web was young, he authored one of the first web-based collaborative environments for large-integer factorization, and was part of the distributed research team that cracked RSA-130. His current interests include Internet stability metrics and the economics of the developing world's Internet markets. Jim received a BS in Computer Science from Yale University.
Abstract: On 7 November 2011 at 14:13 UTC, large parts of the global Internet became unstable or unreachable for nearly half an hour, an event ultimately traced to a routing software vulnerability. We describe the hunt for the origin of this event in both BGP and traceroute-based active measurement data, describe the "BGP epidemiology" of similar events in recent years, and provide some hypotheses as to the origin of the BGP "trigger messages" that caused the November meltdown.
