On-demand media streaming has gained considerable attention in recent years owing to its promising usage in a rich set of Internet-based services such as movies on demand and distance learning. However, the current solutions for on-demand media streaming, primarily based on the client-server model, are not economical and not scalable due to the high cost in deploying the servers and the heavy media traffic overload on the servers.
We propose a scalable cost-effective P2P solution, called Bit-Vampire, that aggregates the peers’ storage and bandwidth to facilitate on-demand media streaming. In this talk, we will discuss the state of the art of P2P on-demand video streaming and in particular present a novel category overlay P2P architecture that enables efficient content search, called COOL (CategOry OverLay) search, and the concept of Bit-Vampire that makes use of COOL search and a scheduling algorithm for efficient concurrent media streaming from multiple peers. Other related practical issues such as efficient pre-release distribution for flash crowd congestion avoidance are also discussed. A movies streaming demo is also presented to illustrate the application of Bit-Vampire that will enable the “Internet DVD player” technology in the future.
Prof. Dr. Son T. Vuong Received his Ph.D. in Computer Science from the University of Waterloo, Canada where he was a lecturer and assistant professor in 1981-1982. Since 1983, he has been a professor in the Computer Science Department at the University of British Columbia in Vancouver, Canada, where he was a founder of the Distributed System Research Group and is now Director of the Laboratory for Networks and Internet Computing (NICLab). He is an international renowned researcher on protocol engineering, distributed multimedia systems, and collaborative computing. His areas of research interest in recent years also include semantic search, p2p video streaming, mobile agent technology and applications, network security, and eLearning. He has (co) authored a US patent, over 180 papers and co-edited three books, including the book on “Recent Advances in Distributed Multimedia Systems” published in 1999. Dr. Vuong served on many conference program committees and was (co)chair and (co)organizer of eight international conferences (Multimedia’08, DMS’08, NOMS’06, DMS'97, ICDCS'95, PSTV'94, FORTE'89, IWPTS'88).
