摘　　要：允许多个协作同时运行是用户和应用对计算机支持的协同工作（ＣＳＣＷ）支撑环境的基本要求，但这一要求使支撑环境的管理和控制变得十分复杂。另外，多数ＣＳＣＷ支撑环境中未能较好地支持带实时多媒体组通信的同步交互功能。提出的高性能ＣＳＣＷ系统支撑环境模型，将管理与控制功能分开，并采用ＯＳＩ的管理者／代理（Ｍａｎａｇｅｒ／Ａｇｅｎｔ）模式管理支撑环境中协作和资源。模型中引入多媒体多点传输、资源管理、连接控制等功能模块以支持带服务质量（ＱＯＳ）保证的多媒体通信。还介绍了基于异步传输模式（ＡＴＭ）网络和工作站实验平台的ＣＳＣＷ支撑环境原型系统ＡＴＭ－ＣＳＣＷＥｎｖ的设计和实现。Complicated control and management functionality is required in CSCW supporting environment which supports multiple collaborations running simultaneously. Synchronous interaction with multimedia real time group communications is another key issue in high performance CSCW supporting environment. This paper presents a new model of CSCW supporting environment. The model separates the management and control aspects of collaborations and resources, and uses the OSI Manager/Agent model to enhance the management functionality. In addition, multi party multimedia communications related issues such as call/connection control, multimedia real time transmission and resource management are considered in the model. This paper also describes the design and implementation of a CSCW supporting environment prototype system on ATM network and Unix operating system platform.
