Wireless digital video broadcasting has experienced much success in years with some industrial systems deployed. We study in this paper how to recover lost packets in video broadcasting by means of a...
VMesh : distributed segment storage for peer-to-peer interactive video streaming (2007)
Yiu, W.-P. Ken, Jin, Xing, Chan, Sheung-Han Gary
Provisioning random access functions in peer-to-peer on-demand video streaming is challenging, due to not only the asynchronous user interactivity but also the unpredictability of group dynamics. In...
Network topology inference based on end-to-end measurements (2006)
Jin, Xing, Yiu, W.-P. Ken, Chan, Sheung-Han Gary, Wang, Yajun
We consider using traceroute-like end-to-end measurement to infer the underlay topology for a group of hosts. One major issue is the measurement cost. Given N hosts in an asymmetric network without...
Cyberclassroom : a large-scale interactive distance-learning platform (2004)
Lin, Siwei, Cheng, Kan Leung, Wang, Rui, Zhou, Hao, Chan, Sheung-Han Gary
Traditionally, lectures are held in classrooms where students are co-located in order to interact with the instructors. This model is not convenient or cost-effective for some students, e.g., those...
TCP and UDP performance for Internet over optical packet-switched networks (2003)
