Description
Summary:Robustness is an important issue in tree based P2P streaming applications. In this paper, a new criterion to evaluate robustness is proposed. The criterion is derived from examining the weakest link of stream sources serving a peer. The quality of connection is defined as how complementary the connection is to the other existing connections in order to improve the completeness of the downloading stream as well as the backup copies. Peers can thus find better connection combination and experience the best stream quality and backup robustness from the existing connections. The collective maximization of robustness among peers rather than maximization of a peer's own resource alleviates the contention for resources, and helps the peers to reasonably allocate and utilize the limited network resources. Simulation results show marked performance improvement over other related proposals in terms of stream quality, speed of recovery from failure and ability to respond quickly to changing overlay and network dynamics.
