摘要

P2P系统不需要集中服务器，网络自组织，具有较高的可扩展性、鲁棒性和容错性。SIP是VoIP和NGN的标准协议，是建立和控制多媒体会话的通用协议。本文提出了一种基于P2P和SIP的实时流媒体共享机制，该机制使用Chord作为底层分布式哈希表(DHT)。我们采用了先进的对等和分段选择算法来解决实时媒体流传输问题。为了解决Tracker服务器故障和瓶颈问题，我们在Tracker服务器上进行了冗余设计。P2P与SIP实时流传输机制相结合，实现了用户注册、媒体资源定位、媒体流会话建立、在线实时播放等功能

A Real-time Streaming Media File Sharing Mechanism Based on P2P and SIP

P2P systems have high scalability, robustness and fault tolerance because of its no centralized server and the network self-organized itself As the standard protocol for VoIP and NGN, SIP is a general protocol for establishing and controlling multimedia session. In this paper, we proposed a real-time streaming media sharing mechanism based on P2P and SIP, which uses Chord as the underlying distributed hash table (DHT). We use the advanced peer and piece selection algorithm to solve the real time media stream transmission. We have a redundancy design on the Tracker server to solve the Tracker server failure and bottleneck problem. The P2P combined with SIP real time stream transport mechanism supports user registration, media resource location, media streaming session establishment, and real-time media streaming playback online
