Josh Karlin Featured in New Scientist Article

April 7, 2009

The article, "UK is ideal home for electronic Big Brother", discusses which countries transmit the most Internet traffic and is a based on a paper, "Nation-State Routing: Censorship, Wiretapping, and BGP", which is a collaboration of graduate student Josh Karlin with Prof. Jennifer Rexford of Princeton and Prof. Stephanie Forrest of the CS Dept. The UK is the second highest on the "country centrality" score (after the US) with Germany taking up the third place. It builds on Josh's work with Autonomous Systems and BGP that Josh focused on for his recent dissertation. It shows that, counterintuitively, the nations who are known to censor the Internet such as China have relatively little impact on international routing, while these top three nations could potentially have a much greater impact.
