The Research And Implementation Of Streaming Media Live System Based On P2P

The paper firstly introduces the related technologies, including peer to peer, streaming media, streaming media transport protocol, P2P streaming media technology and analyzes several typical model based on P2P streaming media; and then introduces some detail description of commonly used method of NAT, and design my own NAT through model.Based on the above theoretical research, the paper designs a streaming live system based on P2P named P2PSLTV using Visual C++, the system model uses tree based topology and the directory architecture server, it can achieve small scale P2P live streaming network. The system's designed in accordance with the order of the design of the whole system, details design of the server and node software's design. The paper makes a depth research on the key modules of the system, including the realization of the peer index server, the achieve of load balancing mechanisms, the construction of overlay networks, the schedule algorithm of streaming media data and the implement of server and client's network address translation through and so on.Finally, the system is tested, and compared with CoolStreaming system, the results show that the system's effectiveness and usability.
