Executive Summary

LIVE media streaming applications have become more and more popular. IP multicast is the most efficient mechanism, but Due to the practical issues of routers, IP multicast has not been widely deployed in the wide-area network infrastructure. The application-level solution build a Peer-To-Peer (P2P) overlay network out of unicast tunnels across cooperative participating users. P2P media streaming has become a promising approach to broadcast non interactive live media from one source to a large number of receivers. Design of a live P2P streaming system faces many challenges. Therefore, no single application-level multicast stream can meet the requirements of everyone. The proposed architecture aims to provide higher streaming quality and to provide robustness.
