摘　　要：高性能的CSCW应用（主要指包含多媒体的同步分布式CSCW应用）是各类CSCW应用中最复杂的一类它不仅要求多点之间多媒体信息的实时传输，还要求复杂的控制及管理功能．本文给出了一种新的基于ATM的高性能CSCW多媒体组通信的体系结构．其中既充分考虑了高性能CSCW系统和应用的通信需求，又充分考虑了ATM底层优势的利用及其对上层通信的影响．本文还介绍了基于此体系结构的高性能CSCW组通信支撑平台的实现．High performance CSCW applications(Synchronous distributed CSCW multimedia applications) are most complicated among all kinds of CSCW applications. They require not only multipoint multimedia real-time transmission, but also many control and management issues. ATM network offers many attractive features to multimedia communications, such as flexible bandwidth allocation and QoS control mechanisms. This paper presents a new ATM-based CSCW multimedia group communications architecture in order to effectively exploit all benefits of ATM. The architecture complies with B-ISDN protocol reference model and separates control (signaling), management and user data platforms. Finally, We introduce the implementation of the CSCW supporting environment based on our architecture.
