摘要 基于多播的多媒体协作系统中,发言权控制(Floorcontrol)是一种重要的协调控制机制,是多媒体协作环境中协调、控制共享资源并发使用的技术。该文在详细分析了floorcontrol协议和主要控制策略的基础上,提出了一种基于多播的实时floorcontrol协议RTFCP,着重对协议RTFCP及其控制策略进行了详细的讨论。同时,对系统的实现及协议的安全性、实时性、公平性进行了讨论。 Floor control is an important coordinative controlling me ch anism in the multimedia cooperative systems based on multicast.It is the techn ology of coordinating and controlling the shared resources concurrently used in the multimedia cooperative environments.Based on the discussions of floor contr ol protocol and its control policies,a floor control protocol for real time mu ltimedia cooperative system(RTFCP)based on multicast is presented.This paper discusses the protocol,a fuzzy control policy and the implementation of the sys tem in detail.At last,the correctness,fairness,and real-time of the RTFCP are discussed.
