Performance Analysis and Implementation of SIP Multi-party Video Conference System

Through an analysis of Session Initiation Protocol (SIP), with a combination of the characteristics of video conference system, this paper puts forward a SIP video conference system based on the hierarchical network architecture. After an exhaustive analysis of the architecture and working principle of the system, this paper comes up with a system implementation method, as well as makes a performance analysis and functional verification of the system by writing corresponding test cases. The experiment results show that this system not only breaks the bottleneck of the existing system, but also efficiently upgrades the system capacity.
