摘要： 已有的会议系统框架大多针对小规模场景。在互联网中，会议系统的控制机制必须能够支持大规模分布式的用户分布。该文提出了一种基于SIP协议的可扩展分布式高可用会议系统管理框架，实现对大规模会议的有效控制。通过将会议的控制功能进行分布式部署，在分布的区域中使用备份机制，增强了系统的可靠性，减轻了网络中不稳定情况对系统的影响。

Abstract: Most conference frameworks focus on small-scale cases, but in Internet, conference management must support huge amounts of distributed users. This paper purposes a scalable and distributed SIP-based control framework with high reliability, which can efficiently manage large-scale applications. It distributes the management components among the participants, and introduces a backup mechanism, which increases the reliability of the whole system and reduces the impact of instability to the system.

Key words: video conference, SIP protocol, conference control
