| 摘 要： | 在传统网络电视直播系统的基础上,提出了一种基于P2P流媒体的在线直播系统架构,它针对流媒体传输要求带宽高、延迟小、实时性强等特点,采用P2P模型中的混合模型,实现了一种动态自适应的区域自治机制.对P2P网络中的信息源进行实时动态分配,极大地提高了各节点间信息传输速率,并且采用RTP、RTSP等流式传输协议,使整个P2P网络的信息传输稳定性、安全性都有一定的保障.

| Abstract: | On the basis of traditional Web TV broadcasting system,the framework of a live broadcasting system based on peer-to-peer streaming media is proposed. Considering that it requires high bandwidth, low latency and real-time characteristics for streaming media delivery,the mixed Web model in peer-to-peer models is applied,and a totally dynamic adaptive self-governing district mechanism is implemented. The streaming information in P2P grids is distributed dynamically, and the streaming media is transferred through RTP and RTSP streaming transfer protocols. The experimental results show that this kind of framework greatly improves the tranafer rate among peers and makes the delivery of streaming media in P2P network much more stable and safer. |
