Brief Biography

Hongtao Guan is currently an associate professor of ICT, CAS. His research interests include visualization technology of computer network and router. Guan studied computer science at Tsinghua University from 1999 to 2010 and obtained BE and PhD degrees. His research on buffered crossbar switch had been published on IEEE/ACM Trans on Networking. Dr. Guan had taken apart the project of BW12000 during 2002 to 2005, the first IPv6 core router in China. The programmable virtual router platform that he has built is a key component for the experimental testbed for future Internet protocols.
