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
