复合式CAD异地协同系统研究

Research on the Composite Architecture of Distributed Collaboration of CAD

在分析异地协同过程及其信息传输实时性要求的基础上,提出了一种复合式CAD异地协同体系结构,其中异地异步协同信息通过B/S结构进行传输,而异地同步协同信息则通过嵌入网页中的协同网络ActiveX插件与专门的协同服务器进行类似C/S结构的传输。详细讨论了基于文档/视图结构的网络插件开发和同步协同操作消息实时可靠传输的实现。

Based on the analysis of the process of distributed collaboration and the Real-time requirement of information transmission, a composite architecture for distributed collaboration of CAD is presented. In this architecture, the distributed asynchronous messages are transmitted by B/S, and the distributed synchronous messages are transmitted by C/S between the special ActiveX in a Web page and the special collaborative server. The development of the special ActiveX based on the document/view architecture and the realization of the reliable transmission of the distributed synchronous messages are discussed in detail.
