Peer-to-Peer Video-on-Demand Streaming Using Multi-Source Forwarding Scheme

Abstract

In a video-on-demand streaming system,each user watches different video fram according to his arrival time . In the paper , the concept of multi-source and forward error correction scheme are integrated to decrease the workload bandwidth of server and reduce the packet loss probability of each peer in the peer-to-peer video-on-demand system. Here, in order to share data to some peers arriving later, each peer must cache part of video data that recently viewed. Each new arrival peer needs to contact multiple sources who have initial part of video data to get video streaming data, and each source transmits different part of video streaming. Once receiving all of these partial streams, the peer will get completely video data. Simulation shows that a suitable preserve time of peers in the system can be used. Thus, the workload bandwidth of server and Memory used by peers can be reduced. Furthermore, the packet loss probability is decreased by the sources diversity and the FEC recovery.
