摘　　要：在参考已有的流媒体代理缓存理论基础上,采用前缀缓存+补丁算法的缓存管理策略,参照流媒体服务器的工作原理,采用RTSP协议作为流传输协议,设计并实现了一种流媒体代理缓存系统。经实验测试该系统提高了系统的字节命中率,进一步减少对网络带宽资源的需求。On the base of the used proxy cache for streaming media, prefix cache ＋ patching algorithm are used which is administration way for cache. Referred to operation principle of streaming media serve and used RTSP protocol. The system of proxy cache for streaming media is achieved. Experimental results show that the sys- tem can improved byte hit rate and significantly reduce the consumption of aggregate bandwidth.
