| Summary: | 碩士 === 國立臺北科技大學 === 工業工程與管理研究所 === 99 === Providing user interactivity in peer-to-peer on-demand video streaming is a significant challenge, such as pause, fast search and reverse search operations of VCR function. In order to provide this type of interactive services, system not only to serve large number of asynchronous user requests, but also need to adjust the P2P overlay topology immediately and allocate the streaming appropriately. If the system is not designed properly, it could lead to longer waiting delay and playback interrupt problems, greatly reducing the user''s service quality. In this paper, we propose a Tree-based Interactive MultimEdia System (TIMES), TIMES combines the P2P streaming service and the concept of multicast transmission. We also designed a list for neighbor set and hybrid caching strategy, so that TIMES can greatly reduce the server bandwidth load, increase system flexibility and also support a large number of interactive and asynchronous user requests effectively.
