摘要 视频点播目前已成为对等(P2P)网络中一项重要的应用,引起了人们极大的研究兴趣。在视频点播系统中,由于用户节点的动态性和VCR操作的复杂性,所以使得资源的定位一直是P2P流媒体点播系统的难题。本文对以往主要的P2PVoD资源定位策略进行了总结和概括,并对典型的视频点播系统的资源定位技术进行了分析和研究,最后在此基础之上指出了P2P视频点播系统资源发现与定位技术未来进一步可研究的工作。 Video-on-Demand,which is an important application in peer-to-peer （P2P） networks, has attracted a lot of research interests recently. Resource location in the video-on-demand system is always a challenging problem because of the peers ’ dynamics and the complexity of VCR operations. This paper presents a summary on the former primary P2P VoD resource discovery and location schemes.Then the key technologies of several typical video-on-demand systems are studied and on this basis,the future work about resource discovery and location in P2P VoD systems is outlined finally.
