协同工作环境下的群组通信模型研究

Research on group communication model for computer-supported cooperative work applications

群组通信通常需要音频、视频、控制信息等多通信通道的支持,目前的通信体系结构模型都不能很好地对各通道之间的同步工作进行有效的描述。本文在对群组通信特点分析的基础上,提出了一个适用于计算机支持的协同工作(CSCW)应用的多通道通信模型,并对各传输通道协议栈之间的依存关系进行了描述,从而比较好的解决了CSCW工作环境下的不同传输媒体协议栈之间的协调问题。

Group communication is usually required to open several communication channels, such as sound, video and cortrol information etc, but synchronization is not expressed effectively with current communication architectures. Based on the analysis of group communication characteristic, a novel approach to the development of communication software that satisfies the requirements imposed by computer-supported cooperative work （CSCW） multimedia applications is proposed, and dependencies for different protocol stacks are described. Furthermore, conformity is solved efficiency among different protocol stacks
