We propose a decentralized Peer-to-Peer (P2P) Videoon-Demand (VoD) system. The traditional data center architecture is eliminated and is replaced by a large set of distributed, dynamic and individually unreliable helpers. The system leverages the strength of numbers to effect reliable cooperative content distribution, removing the drawbacks of conventional data center architectures including complexity of maintenance, high power consumption and lack of scalability. In the proposed VoD system, users and helper "servelets" cooperate in a P2P manner to deliver the video stream. Helpers are preloaded with only a small fraction of parity coded video data packets, and form into swarms each serving partial video content. The total number of helpers is optimized to guarantee high quality of service. In cases of helper churn, the helper network is also able to regenerate itself by users and helpers working cooperatively to repair the lost data, which yields a highly reliable system. Analysis and simulation results corroborate the feasibility and effectiveness of the proposed architecture.
