Abstract
The interest for video delivery systems over the Internet has been gradually growing up last years. It has already become a major application due to client interest of video content and persistent development of network technologies. Recently, Peer-to-Peer (P2P) network plays as an important technology to implement such systems. As a fast growth in population of P2P-VoD system, user behavior is playing an increasingly crucial role in the performance of video system. This chapter proposes an efficient model for P2P-VoD system based on the analysis of the user behavior. The simulation results show that the proposed model can efficiently improve both server load and the initial playout latency.
