George Varghese’s powerful algorithms for packet-switching networks are an integral part of Internet routers, enabling data transfer that is safer, faster, and more reliable. Dr. Varghese pioneered the development of network algorithmics, which has enabled the proliferation of packet-switched networks. Network algorithmics involves changing hardware and operating systems and applying efficient algorithms to reduce Internet bottlenecks. Dr. Varghese’s Deficit Round Robin packet scheduling algorithm supports real-time audio and video over the Internet and has been incorporated into practically every Internet router used. His algorithms for fast Internet protocol lookups overcame the perception that route lookup was slow.
An Association for Computing Machinery Fellow, Dr. Varghese is currently a principal researcher with Microsoft Research, Mountain View, CA, USA. He was formerly a professor at University of California, San Diego, CA, USA and earlier at Washington University, St. Louis, MO, USA. Varghese was the recipient of the 2014 IEEE Koji Kobayashi Computers and Communications Award.
