Peer-to-Peer (P2P) networks have been shown to be a promising approach to provide large-scale Video on Demand (VoD) services over Internet for its potential high scalability. However, for a normal peer, how to efficiently schedule media data to multiple asynchronous peers for VoD services in such networks remains a major challenge. These systems dramatically reduce the server loading, and provide a platform for scalable content distribution, as long as there is interest for the content. The main challenges reside in ensuring that users can start watching a movie at any point in time, with small start-up times and sustainable playback rates. In this work, we address the challenges underlying the problem of near Video-on-Demand (nVoD) using P2P systems, and provide evidence that high-quality nVoD is feasible. In particular, we investigate the scheduling problem of efficiently disseminating the blocks of a video file in a P2P mesh-based system, and show scheduling algorithm can provide significant benefits and the experimental results will show that load sharing scheduling performs significantly better than other dynamic algorithm, network coding.
