P2VoD: providing fault tolerant video-on-demand streaming in peer-to-peer environment

We present a system for video-on-demand streaming in peer-to-peer environment. We start by realizing the major differences between two types of streaming: live and on-demand. These observations lead to a set of problems that need to be solved for a peer-to-peer video-on-demand system. To address these problems, we propose a solution, which includes detail algorithms for building and maintaining an application multicast tree. The novel ideas in this paper are the use of a new caching scheme at clients, and the introduction of generation for better client management. Performance study based on simulation is carried out. The results show that our system outperforms a recently proposed system in a number of important performance metrics.
