摘要
介绍了SIP协议(Session Initiation Protocol)的相关知识,在其基础上探讨了SIP协议性能测试的方法。该方法中提出了基于基本呼叫流程的测试方案,并对方案中SIP信令和媒体流的NAT穿越问题作了深入分析,用这种测试方法能够支持大量的流媒体并发的测试,突破了对流媒体编译码的难点。
This paper introduced the basic knowledge of SIP protocol （Session Initiation Protocol）, and discussed the method of testing the SIP protocol.This method proposed a test scheme based on the basic call flow,and intensively discussed the NAT penetration of the SIP signaling and media streams, this method supports testing media streams simultaneously, and it solves the difficulties of coding and decoding the media streams.
