Abstract
Recently, peer-to-peer (P2P) overlay networks have become popular and many P2P applications such as file sharing and content distribution have been introduced. Naturally, P2P cooperative caching schemes for streaming were introduced. However, these approaches manifest inefficiency of cache utilization due to inappropriate cache replacement algorithms, and no consideration of dynamic membership changes of peer nodes. In this paper, we investigate an efficient cooperative caching mechanism for VOD streaming service over P2P overlay networks. The target of the system is to provide low-latency and high-quality services by virtue of pees' collaboration. The storage and replacement of caching content are based on segment-based strategy. And a utility-based fine-grained cooperative cache (DUFQ policy was proposed for cache replacement. We demonstrate the effectiveness of the proposed scheme and compare with traditional LRUF scheme through extensive simulation experiments over large, Internet-like topologies.
