Taking advantages of both CDN and P2P networks has been considered as a feasible solution for large-scale video stream delivering systems. Recent researches have shown great interested in CDN-P2P-hybrid architecture and ISP-friendly P2P content delivery. In this paper, we propose a novel VoD scheme based on CDN-P2P-hybrid architecture. First, we design a multi-layer CDN-P2P-hybrid overlay network architecture. Second, in order to provide a seamless connection for different layers, we propose a super-node mechanism, serving as connecting points. Third, as part of experiment works we discuss CPH-VoD implementation scheme based on peer node local RTSP server mechanism, including peer download/upload module, and their working processes. The experimental results show that VoD based on CDN-P2P-hybrid is superior to either pure CDN approach or pure P2P approach.
