摘　　要：传统的流媒体系统建立在客户/服务器模式的基础上,网络带宽高,稳定性差,系统伸缩性差,服务器常常成为系统的瓶颈。而P2P技术在充分利用客户资源、提高系统伸缩性等方面具有巨大的潜力。针对这些问题,探讨了基于P2P的流媒体技术,并提出了一种基于P2P的流媒体传输模型,详细介绍了该模型所具有的优势。Providing streaming service over the Internet is a challenging problem. First, it is not a trivial task to stream on an end-to- end basics of a video＇s high number bandwidth requirement and stability and long duration. Second, scalability issues arise when attempting to service a large number of clients. Traditional streaming service employs a Client-Server unicast service model. The P2P technologies have huge potential on resource usage and system scalability, P2P-based stream media technology is discussed, a model of P2P-based streaming media is bronght, and the advantage of the model is presented.
