| 摘 要： | 现有的流媒体系统一般是基于客户／服务器模式和IP组播技术，这限制了用户数量且IP组播需先得到ISP支持，故其发展受到很大限制。而在P2P网络中，每个接收数据的用户同时向外转发数据，这就充分利用了以往忽视的客户机资源。首先指出了P2P流媒体应用中所面临的挑战，并着重从应用层多播树、网络异构性、激励机制等方面阐述了P2P流媒体的研究现状，分析讨论了存在的问题，最后指出进一步的研究方向。

| Abstract: | Current media streaming systems are often based on the client-server framework and IP-level multicasting supported by ISP, which limits clients amount to a great extent. In P2P network, each client receives data and forwards it to others at the same time. So large numbers of clients resource ignored before can be effectively used. Firstly challenges in P2P media streaming applications were pointed out, then some recent research results such as application-level multicast tree, heterogeneity of network and incentive mechanism and so on were introduced. Some existent problems and some remained issues for further research were discussed. |
