The high bandwidth required by live media streaming limits the number of users, and the quality-of-service (QoS) for media streaming is usually unsatisfactory. This paper presents a novel P2PStreaming model: CoopStreaming (Cooperative Streaming). CoopStreaming tries to achieve a better trade-off, by leveraging the advantages in both P2P and C/S. The core operations in CoopStreaming are very simple: every node periodically exchanges data availability information with a set of partners, and supplies available data to partners. We emphasize four salient features of CoopStreaming: 1) easy to implement, as it does not have to construct and maintain a complex application multicast tree; 2) robust and resilient, as the partnerships enable adaptive and quick switching among multi-suppliers; 3) scalability, as media data distributed in a P2P manner, more users, more quickly. 4) heterogeneity adaptive, as deployed the Progressive Fine Granularity Scalable (PFGS) coding. Extensive simulation results show that the average latency, control overhead, and video quality in our model are all better than those in gossip-based network and tree-based network. © Springer-Verlag Berlin Heidelberg 2005.
