Partial Video Replication for Peer-to-peer Streaming

Abstract. Video streaming over peer-to-peer networks has attracted a lot of interest recently. However most of the research on streaming in peer-to-peer networks focused on schemes where all the clients have the whole movie. In this paper we propose schemes where clients store only partial movie after viewing the movie. We propose cooperative schemes where replication is done in a way that maximizes a global function and uncooperative schemes where each node makes replication decision independently. We evaluate both schemes using extensive simulation. Simulation results show that cooperative schemes perform better but they are harder to implement and maintain. Uncooperative schemes are simpler, based on a distributed algorithm but they suffer from lower performance
