Abstract: After studying some existing general CSCW platforms, the authors have found some of their common disadvantages, like not supporting extending core functions, poor performances. Therefore, this paper presents a design of general CSCW platform, which can get rid of these disadvantages. This design adopts protocol stack based network transport model, distributed cache, implementation and testing show that this design can dramatically increase extensibility and performance of the system.

摘要： 通过对一些现有CSCW通用平台的研究，发现它们有一些共同的不足之处，如无法对核心功能进行扩展、系统性能较差等。该文提出了一套CSCW通用平台设计方案，对不足之处进行了改进。该设计方案采用了基于协议栈的网络通信模型、分布式缓存，通过实现和测试表明该设计方案可显著地提高系统的扩展性和性能。
