摘　　要：多媒体数据要在网络上传输,必须先对多媒体数据进行流化处理。要想流化多媒体数据,就需要流媒体服务器。所以流媒体服务器对多媒体数据的传输有着至关重要作用。其中流化处理就是对多媒体数据进行封装,把音视频数据打包成能进行流传输的数据包。而且提高流媒体服务器的性能一个有效途径是提高缓存的利用率,使系统为更多的媒体流服务。文章以RTMP为基础,首先分析了该传输协议,并提出了一种改进的缓存策略,使流媒体服务器性能有了提高。Multimedia data must be flowing processed in the streaming media server in order to conduct transmission on Internet.Therefore,the multimedia streaming server has a vital role in the transmissions of multimedia data.The flowing process is that encapsulating the media data.The audio and video can be packetaged into a packet for streaming transmission.And improving the performance of streaming mediaserver is an effective way to improve the utilization of the cache,in order to deal with more media streams.First,the transport protocol is analyzed based on RTMP.And an improved cache policy is proposed,the streaming media server performance has been improved.
