摘要:
在基于C/S结构的集中服务式的传统视频点播系统中,服务器和网络带宽都会成为瓶颈,不能满足用户的需求。文中以消除传统视频点播系统中的瓶颈为目标,在视频点播系统中引入P2P技术,基于开源的高效文件共享和下载软件BitTorrent,通过改进,设计了一种P2P视频点播系统。该系统采用了集中目录式P2P结构和基于分片机制的边下载边播放模式,引入并改进了多重滑动窗口模型,具有良好的响应特性。设计了一种先下载后观看的模式,该模式可在现有的网络条件下,提供非实时的高清影片点播业务。仿真实验结果表明文中的设计有效地解决了
Abstract:
In the traditional video on demand system which adopts the central sever mode based on C/S structure,server and bandwidth become the bottleneck,so the system can't satisfy the request.In order to resolve this problem,P2P technology was introduced into video on demand system,and a P2P video on demand system was designed based on the improvement of open source BitTorrent software which is a good file sharing and download tools with high efficiency.The system adopted central directory P2P structure and the fragment-based pattern of playing along with downloading.Sliding window mechanism was adopted and extended.This design make the system gain well response performance.Furthermore,the system provides service of high definition films with the pattern of playing after downloading.The simulation results showed that the design can effectively resolve the bottleneck problem in traditional VOD system
