允许多个协作同时运行是用户和应用对 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 .介绍了基于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 .该支撑环境将管理与控制功能分开 ,并采用 OSI的 Manager/ Agent模式管理支撑环境中协作和资源 .环境中还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 Qo S保证的多媒体组通信
Allowing multiple concurrent operations to run simultaneously is a fundamental requirement of users and applications for the CSCW support environment, but this requirement complicates the management and control of the support environment.In addition, most CSCW support environments are not well supported with real-time multimedia Group communication.It introduces the design and realization of the prototype system ATM-CSCWEnv of CSCW supporting environment based on ATM network and workstation experiment platform.This supporting environment separates the management and control functions and adopts OSI Manager / Agent mode management support Environment collaboration and resources.Environment also introduces multimedia multi-point transmission, resource management, connection control and other functional modules to support Qo S-guaranteed multimedia group communication
