In this system, we introduces cluster architecture to provide global and scalable streaming caching proxy service mechanism; We implement streaming media transfer protocol on caching proxy end; We implement layered caching mechanism (global disk caching and memory caching) using dynamic sharing running memory buffer algorithm to support more stable and real-time parallel streams; We implement client request aggregation by means of streaming session sharing to reduce disk I/O and serve more user; We propose single streaming image to support the unify of pre-fetching streaming and caching streaming, which guarantees the proxy streaming of transparency for client; We design and implement streaming pre-fetching mechanism based on packet feedback information to reduce the number of "rebuffering" on client end; We bring forward streaming caching admission control policy fit for streaming caching proxy server to guarantee the QoS of streaming service.

该系统引入集群架构以提供全局的、可扩展的缓存代理服务机制；实现了缓存代理端的流媒体传输协议；采用动态共享运行缓冲区算法实现了分层缓存机制(全局磁盘缓存和内存缓存)以支持更多稳定、实时的并发流；利用流会话共享机制实现了客户请求聚集，从而减少磁盘I/O同时能服务更多的客户；提出了单一流映像，以支持预取流和缓存流的统一，从而保证代理端服务流对客户的完全透明；设计并实现了基于包反馈信息的流数据预取机制，从而减少了客户端的"rebuffering"次数；提出了适合于缓存代理服务器的流缓存准入控制策略，保证了流服务的QoS。

As one of famous work that often abandon a gentleman, huang Lei, Jiang Qin diligent, Zhao Baogang, yuan autumn wait for actual strength to go out act " 4 worlds are the same as hall " when actor is mirrorred sultrily, also caused a netizen to be opposite old 1985 edition " 4 worlds are the same as hall " nostalgic heat, daily number netizen is chased after read old old edition anthology of classic theatrical work, savor authentic Beijing taste.
