支持协同应用的一种组通信方案的设计和实现

Design and Realization of a Group Communications Project Supporting Cooperative Applications

协同应用在分布系统应用中是一个很有前途的新领域 ,该应用对分布技术提出了新的要求和挑战。在这种新的分布环境中 ,对象组模型是问题的关键所在。在本文中 ,我们基于 CORBA平台 ,针对 CSCW应用的要求 ,提出了一种对象组模型 ,介绍了组模型中各类对象之间的交互和协调关系 。

Cooperative application is a new pr ospective field in the domain of distributed system applications.This new type o f application also poses new demands and challenges for the distribution technol ogy.In the new distributed environment,the object group model is a key problem.B ased on traditional CORBA services and with the demand of CSCW applications,an o bject group model is given,the interaction and cooperation of different objects in the group model as well as the IDL (Interface Definition Language) descriptio n and explanation of main objects are introduced in this paper.
