The state-of-the-art of on-demand P2P media streaming over the Internet

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 peerspsila 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 movie streaming demo is also presented to illustrate the application of Bit-Vampire that will enable the ldquoInternet DVD playerrdquo technology in the future.
