A peer-churn resistant video multicast system over P2P networks

This work presents a peer-churn resistant video multicast system over P2P (Peer-to-Peer) networks. Because peers typically display dynamic and unstable behavior during a session, a P2P video streaming multicast tree must take into account both the link delay and the peer stability in order to achieve a seamless video streaming multicast service with a low delay. Hence, we need to update the multicast tree dynamically according to its time-varying environments in order to achieve an effective tradeoff between the route delay and the relative peer stability. Finally, simulation results are provided to demonstrate the performance of the proposed system.
