使用CORBA实现各种分布式应用系统的策略

The Strategies of Implementation of Distributed Application Systems by Using CORBA

1 引言随着计算机网络应用的不断深入和普及,大规模的计算机网络将不断增加。在这种计算机网络中,不仅硬件设备型号、种类、规模相异,而且操作系统平台、程序设计环境及应用也各不相同,这就是大规模计算机网络的重要特征——异构性。人们迫切希望在这种计算机网络上共享信息、设备和软件,这就要求支撑这种应用的分布式系统具有良好的互操作性、可迁移性和可重用性,集成各组件产生一个连贯的可操作的异构系统。然而,处理分布计算环境中的异构性是很不容易的,特别是开发支撑并有效地利用异构的网络系统的应用软件和组件是非常棘手的。

Building highly available applications and real-time applications is very hard by using conventional implementation of CORBA. In this paper,we mainly introduce the structures of COR-BA systems supporting highly reliable applications and real-time applications,discuss the important problems to be solved,and finally consider the strategy of developing distributed applications by using Java Applets and CORBA.
