摘　　要：P2P流媒体系统主要涉及成员管理和数据调度等两方面研究。主要研究内容为不同的网络拓扑结构下的数据调度问题的研究问题。P2P流媒体系统网络拓扑结构主要分为三类:树状结构、网状结构和混合结构。树状结构又分为单组播树和多组播树结构,主要采取"推"模式的数据调度机制。网状结构主要采取"拉"模式的数据调度机制。混合结构主要采取"推-拉"模式的数据调度机制。通过介绍每一类方法和相应的代表系统,并给出各类数据调度的优缺点。The research mainly involves two aspects of member management and data scheduling in P2P media streaming system. The main content of this paper is to review the research on data scheduling problem under different network topological structures. The network topology structures of P2P media streaming system were divided into three categories： tree structure, network structure and mixed structure. The tree structure was divided into single multicast tree and muhicast tree structure, mainly took the ＂push＂ model of data scheduling mechanism. The network structure mainly took the ＂pull＂ model of data scheduling mechanism. The mixed structure mainly took the ＂push-pull＂ model of data scheduling mechanism. The classical technologies and representative data scheduling mechanisms were investigated in this paper, and the merits and demerits were given.
