Updates

new [Nov 2012] Our work on measuring IPv6 deployment, routing, and performance (a.k.a. "IPv6 Will be Deployed Any Day Now") appeared at IMC 2012 (paper) (slides).

new Seriously, any day now, now, or now

new [Nov 2012] I gave a tutorial titled "The Structure and Evolution of the AS-level Internet" at the Workshop on Internet Topology and Economics at Georgia Tech (slides)

new [June 2012] We analyzed peering strategy adoption by transit providers using an analytical game-theoretic model. In presented this work at the Workshop on Pricing and Incentives in Networks (W-PIN), June 2012 (slides). The resulting paper appeared at the Sigmetrics Performance Evaluation Review, Sept 2012.
