摘要
视频会议系统中会议服务器决定着会议的稳定性、规模和质量。通过研究SIP协议、SIP协议实体和SIP视频会议中服务器的结构等,对现有结构和服务器进行了改进和设计。采用负载均衡方法,提高了系统动态自适应能力,扩大了视频会议的规模。利用SIP消息分发以及优先处理机制,进一步提高了视频会议服务器的消息处理效率,以解决消息并发和消息拥塞的问题,提高系统的可靠性。
In video conference system, the server determines the stability, capacity and quality of the video conference. The SIP protocol, SIP protocol entities and SIP video conference server structure are researched in this paper, and the existing structure is improved and the server is designed. With the method of load balance, the dynamic adaptive ability of the system is improved and the capacity of the system is expanded. Besides, with distribution of SIP messages and priority handling mechanism, the message processing efficiency of the video conference server is raised to solve the problems of message concurrency, message congestion, and improve system reliability.
