In this paper, we consider Peer-to-Peer Videoon-Demand (P2P VoD) systems based on the BitTorrent file sharing protocol. Since the rarest first policy adopted in the BitTorrent protocol could not collect all pieces corresponding to a video file by their playback time, we need to develop a new piece selection rule particularly designed for P2P VoDs. In the proposed scheme, we assume the existence of a media server which can upload any piece upon request, and try to bound the load of such media
