The Peer-to-Peer solution provides a service model that is attractive for Video-On-Demand (VOD). The key idea of using P2P technology is to aggregate storage and bandwidths capacity of peers to alleviate workload on the source server. Compared with P2P live streaming, it is much more challenge for VOD due to peers' asynchronous request, different interested portion and support for VCR-like operation. In this paper, the authors utilize two-scale list of peers, which is composed of R-peers and S-peers, to locate collaborator and support VCR operation. Demand-driven chunk swarming is proposed to exchange data with ragged collaborators in the VoD system. Simulation results show that the source server load is significantly reduced, playback continuity is guaranteed and the method supports VCR operation quite well.
