【摘要】 <正> 1 概述随着流媒体应用程序在互联网上的广泛应用,必将给Internet的负载带来巨大的变化。基于包交换的Internet不是为实时、不间断的流媒体传输而设计的,因此互联网上的流媒体系统将受到了以下4个方面的限制。·质量限制流媒体服务器通常位于请求者很远的地方,这增加了可用路径的数量,同时也增加了包传输的跳转(hop)数,从而增加了包的延迟时间和包丢失的可能性,势必影响到用户的播放质量。更多还原

【Abstract】 With the widespread use of streaming media application on the Internet, a significant change in Internet workload will be provoked. Caching is one kind of applied technique relatively for enhancing the scalability of streaming system and reducing the workload of server/network. We have utilized RTP/RTSP protocol, and implemented the prototype of streaming proxy caching based on LAN in visual C++ environment with WINSOCK network interface. This system can play a role in decreasing server load, reducing the traffic from streaming server to proxy, and improving the Start-up latency of the client.更多还原
