| 摘 要： | 论文提出一种结构化新方法,它能通过动态配置支持基于组件的分布式软件的容错。采用面向图形的编程模型,基于组件的分布式软件的软件体系结构可用一个逻辑图来表示,该逻辑图可以精化为一个明确的对象并分布到网络中,软件的动态配置通过执行定义在图上的一系列操作来实现,发生错误时通过动态重配置软件来支持容错。论文描述了该方法的基本模型、系统结构及其在CORBA上的实现原型。

| Abstract: | This paper presents a novel,architectural approach to support fault tolerance in component-based distributed software(CBDS)through dynamic reconfiguration.Using the graph-oriented programming(GOP)model,the software architec-ture of a CBDS is specified by a logical graph which is reified as an explicit object distributed over the network.Dy-namic reconfiguration is implemented by executing a set of operations defined over the graph.The approach supports fault tolerance by dynamically reconfiguring the CBDS upon detection of faults.The authors describe the basic model,the system architecture and its prototype implementation on top of CORBA. |
