P2P video streaming replication scheme for P2P VoD services

In P2P Video-on-Demand (VoD) services, the storage size of lightweight devices is limited so that they can only store the partial video data rather than a complete file. Therefore, peers cannot find the required video data from neighbor peers, and then fetch the video data from the video server thus increasing the bandwidth load of video server. In this paper, we propose a P2P VoD replication scheme to reduce the bandwidth load of video server. Peers can adaptively replicate video data under the storage space limitation. The experimental results show that our schemes can reduce 30% bandwidth load of the video server.
