| 摘 要： | 采用多代理结构和对操作系统的内封装，将应用程序的操作命令提取出来，在异地系统间共享。讨论了建立面向窄带环境的异地同步协同设计支撑平台的关键技术，在体系结构上提出了一个基于操作信息共享的C／S结构。其中服务器上采用的协同管理方式和流量调节技术有效地保证了窄带环境的实施；客户机端的事件驱动与响应机制则严格实现了异地同步协作。按照这种思想建立的操作平台能够支持在地理上分布的工作团队通过低带宽的Internet，安全、实时地进行基于三维图形的异地协同工作。

| Abstract: | The narrow bandwidth environment is taken into account to solve the problems in computer supported collaborative design(CSCD) mode. After discussing the key issues to overcome the obstacle, this paper presented a C/S architecture based on the operation information sharing. The collaborative management and policy based traffic adjusting technology was adopted in the server. Accordingly, the clients use the event handler to ensure that the operation information among collaborators can be processed and responded in time. The operation platform based on the algorithm can support team work effectively and is successfully implemented on CAD software (Unigraphics) through LAN and the Internet. |
