网络边沿缓存能够加速流媒体的传输,它是一种提高Internet上流媒体服务性能的技术。为了减少流媒体服务启动延时与抖动,降低流媒体服务器服务时的资源(CPU的利用与网络带宽)消耗,提出了基于客户端缓存代理系统解决方案,且对所提出系统的RTSP协议进行了实现。 Network edge cache can accelerate the transmission of streaming media, it is a technology to improve the performance of streaming media services on the Internet. In order to reduce the delay and jitter of streaming media service and reduce the consumption of resources (CPU utilization and network bandwidth) in streaming media server service, a solution based on client-side caching proxy system is proposed and the RTSP protocol of the proposed system is implemented achieve.
