摘要
分析已有针对RTP/RTCP媒体流的测量机制,提出了一种在网络中部署测量点,进行网络性能分段测量的方法。通过测量点发送额外的RTCP RR报文,测量点分析SR和额外的RR报文,实现对媒体流的网络性能分段测量与监控。在linux环境下开发测量点模块,实现该测量方法。实验结果表明该方法对网络影响小,复杂度低,具有可行性。
Based on the analysis of existing RTP/RTCP media stream measurement machanizm, a network seg- mentation measurement method of media stream was proposed. In the method, measuring points are deployed in network. Media stream network segment performance is mesured and monitored by measurement and analysis SR and extra RR packets sent from measurement points. The measurement system is implemented on Linux system. The experimental results showed that measurement by the method has small impact on network, low complexity and is feasible.
