摘要
发言权控制(Floor Control)是多媒体会议中会议控制的一部分,用来协调参与者对底层共享资源的使用,它直接关系到会议的服务质量。文章利用会话初始协议(SIP)的可扩展性,在SUN公司为实现SIP应用而提供的一套Java接口(JAINSIP)架构下设计并实现了SIP多媒体会议系统的发言权控制系统,该系统具有控制方式多样化,适用于分布式系统等特点。测试结果表明系统设计合理,并具有延迟较小的特点,满足分布式系统的要求。
As a part of the conference control in Multimedia Conferencing Systems （MCS）, floor control is used to coordinate the access to the shared resources among the participants, which has a direct bearing upon the QoS of the system. In this paper, the floor control in SIP-based MCS is realized in the architecture of JAIN SIP by using the scalability of the Session Initiation Protocol （SIP）, which is characteristic of diversity in the way of control and adaptability to distributed systems. The test results show that the system design is rational and the delay is tolerable.
