| 摘 要： | 针对3Tnet(高性能宽带信息示范网)的背景,利用3Tnet数据高速传输的特点,设计了适合该网络的基于多级代理缓存的视频点播服务策略.该策略中,边缘流媒体服务器直接向用户提供流媒体服务,中心服务器存储影片采用异地点播技术提供服务.实际运营效果表明,该策略可以有效地缓解中心服务器的压力,并对客户端提供零启动延迟服务,适合大规模IPTV商业运营.

| Abstract: | Based on the 3Tnet(China high-performance broadband information network),in order to use sufficiently the high bandwidth,a transmission scheme for multi-proxy-based video-on-demand was designed for the context of large-scale video-on-demand application.In the scheme,the edge media server directly served the request clients and the proxy caching was used between the center server and the edge media server.The result of actual business management proves that the proposed scheme can greatly reduce the load on the center server and provide null startup latency for clients. |
