P2P视频点播内容分发策略

Video-on-Demand,which is an important application in peer-to-peer(P2P)networks,has attracted a lot of research interests recently.As P2P network is easy to deploy and can provide a large-scale substrate networks, many P2P VoD content distribution schemes have emerged to offer the basic function of data transportation.This paper presents a survey on the state-of-the-art P2P VoD content distribution schemes.It first summarizes the key issues in designing P2P VoD schemes and then categorizes these schemes into four groups according to data transportation method.Finally,it discusses the application-level performance and outlines possible future work.
