| Summary: | 碩士 === 國立臺北科技大學 === 資訊與運籌管理研究所 === 101 === Of all the current network data transfer architectures, P2P architecture is one of the most popular architectures. It could reduce server loading compared to traditional client-server architecture. With prevalence of multimedia, more and more VoD (video-on-demand) systems are applied on P2P architectures. In this paper, we propose P2P streaming for multiple descriptions coding (MDC) video. The proposed method allows users with different bandwidths watching the same video. We first divide a video file into segments, and then divide those segments again by using MDC. Then, we design an adaptive access mechanism to make services not only available for users but also transferrable to another user. The simulation results indicate that the mechanism is suitable in P2P architecture. What’s more, the mechanism can significantly reduce the server load.
