摘要：

Large-scale stream media delivery over Internet is one hot and hard problem. Three main solutions have been developed for this purpose. Content delivery network (CDN) can provide high quality streaming service with high cost. Server-based proxies are cost- effective but not scalable due to the limited proxy capacity and its centralized control. Peer-to-Peer (P2P) network is scalable but does not guarantee high quality streaming service due to its self-restrained characteristic. This paper proposes a new chunk-based scalable and reliable proxy scheme for P2P network. Clients arc self-organized in unstructured P2P VoD system GridCast and requests for media contents that are not found in P2P overlay from proxy servers. This scheme can address the limitations of server-based proxy model and client-based P2P model. The proposed scheme is evaluated by trace-driven simulations from logs collected in GridCast. The results show that the approach proposed significantly improves the quality of media streaming and the system scalability
