摘　　要：该文设计并实现了一种分布式、松耦合的多媒体会议系统。该系统采用独特的数字—模拟混合组网技术,利用IP组播完成视音频数据流的分配和系统状态的监测,并借助代理机制实现了完全对等的分布式体系结构。实际使用表明,与传统的基于H.323协议的多媒体会议系统相比,这种系统具有更好的扩展能力和可维护性。A distributed and loosely coupled multimedia conference system is designed and implemented in this paper.The system uses a special digital-analog hybrid networking technique.And it uses IP multicasting to transfer the video,audio,and monitoring streams.An agent mechanism is incorporated in this system to implement the distributed peer-peer architecture.According to the engineering experience and the users' feedback,the scalability and maintenance of the de-sign are easier to be achieved than that of the conventional H.323multimedia conference system.
