| 摘 要： | 现有的P2P流媒体资源定位算法中,多以主动查询为主,尤其是在非结构化网络中,搜索效率低下,资源耗费巨大,最终导致用户延迟播放.基于发布订阅的定位算法-PSS,通过快速预取的思想,结合视频块的优先级,可有效解决该问题,使播放连续度明显提高,搜索消耗明显降低.

| Abstract: | The P2P stream media resource location algorithm mainly with active query, are mefficient ano consume larger system resources especially in mesh structure, which causes a longer play-delay time. This paper proposed the transport protocol PSS algorithm based on publish/subscribe. Using fast prefetehing idea combining the priority of video blocks, it effectively solved the problem above, obviously improved play process and reduced the search consumption significantly. |
