Research and Improvement of the server in the SIP video conference

In video conference system, the server determines the stability, the capacity and quality of the video conference. This paper researched SIP protocol, SIP protocol entities and SIP video conference server structure, improved the existing structure and designed the server. With the load balance methods, the dynamic adaptive ability of the system was improved, the capacity of the system was expanded. Besides, with distribution of SIP messages and priority handling mechanism, the message processing efficiency of the video conference server was raised, to solve the problems of message concurrency and message congestion, improve system reliability.
