This is of particular significance for peer-to-peer P2P video-on-demand VoD related platforms faced with an immediate and growing demand for reliable service delivery. In response to demands for high-quality video the key objectives in the construction of the proposed framework were user satisfaction with perceived video quality and the effective utilization of available resources on P2P VoD networks. This study developed a peer-based promoter to support online advertising in P2P VoD networks based on an estimation of video distortion prior to the replication of data stream chunks. The proposed technology enables the recovery of lost video using replicated stream chunks in real time. Load balance is achieved by adjusting the replication level of each candidate group according to the degree-of-distortion thereby enabling a significant reduction in server load and increased scalability in the P2P VoD system. This approach also promotes the use of advertising as an efficient tool for commercial promotion. Results indicate that the proposed system efficiently satisfies the given fault tolerances.

Introduction Recent advances in online advertising and peer-to-peer P2P video-on-demand VoD networks enabling peers to watch or download internet video clips on demand have created considerable interest in the construction of integrated frameworks.
