摘要
随着Internet的快速发展,视频点播的应用越来越广泛,但是目前广泛采用的IP单播传输方式使骨干网和服务器在点播用户增多的时候不堪重负,而目前组播方式和代理服务器方式因为各种原因而不能大规模应用于Internet。本文提出了一种基于对等网络(P2P)的视频点播系统模型,该模型采用了一种全新的滑动窗口机制对用户端缓存进行管理并对用户上行信道加以利用,从根本上解决骨干网和服务器负载过大的难题。
With the rapid development of Internet, the orders of applications for VOD are more and more widely. Butservers are unbearable heavy burden at the time of orderings increase quickly if server transfer data by IP unicast .Due to Multicast and Proxy-Based distributed VOD are not available currently, the paper introduced a P2P-BasedVOD system, the system took new slip window technology to make use of buffers and upstream channel of users,therefore, solved the problems of overload of server.
