Abstract


In P2P streaming media , video on demand (VOD) is the most common and popular type of application. It takes full advantage of broadband network resource sharing, resource utilization to maximize the advantages , to provide users with a more economical , more extensive interactive film, television and music services. Compared with P2P streaming media forms , because based on the traditional C / S structure of demand during high interactivity enables the server is difficult to meet the needs of large-scale on-demand , so the relatively slow pace of development of VOD technology . From the user 's perspective, today's streaming media there is not high -definition video , playing before the need to be cached on the local hard drive , the player can not be drag operation and other issues. Therefore, the design and build an efficient VOD system , to meet the needs of customers , the VOD system is an important prerequisite to gain popularity . First VOD system for the current status and lack of clearly pointed out in a P2P environment to achieve video -on-demand content distribution system development necessity . On this basis , analyzing P2P video -on-demand content distribution system's main functions and core processes. Then discuss the video -on-demand content distribution system's overall architecture and Session Manager , fragmentation / Data Manager and P2P network core subsystem design and communication, data transmission and analysis of P2P messaging session , DirectShow application of key technologies such as . It focuses on how to use the Session Manager VOD strategy to achieve distribution mechanism . Multiple runs in the system after testing , can achieve the desired effect on demand , can effectively resolve the server bottleneck problem.
