Performance Evaluation of Distributed Prefetching for Asynchronous Multicast in P2P Networks

Abstract. We consider the problem of delivering real-time, near realtime and stored streaming media to a large number of asynchronous clients. This problem has been studied in the context of asynchronous multicast and peer-to-peer content distribution. In this paper we evaluate through extensive simulations the performance of the distributed prefetching protocol, dPAM [20], proposed for scalable, asynchronous multicast in P2P systems. We show that the prefetch-and-relay strategy of dPAM can reduce the server bandwidth requirement quite significantly, compared to the previously proposed cache-and-relay strategy, even when the group of clients downloading a stream changes quite frequently due to client departures.
