一种面向图的分布式软件动态配置和容错方法

A Graph-oriented Approach for Dynamic Reconfiguration and Fault Tolerance in Distributed Software

提出一种新的方法,通过动态配置对基于组件的分布式软件的容错提供支持。此方法采用面向图的GOP编程模型,将整个分布式软件的体系结构用一张逻辑图来描述,系统的动态配置可以通过执行图上预定义的一组操作来完成。检测到故障或异常的时候实施这种动态配置能够支持系统的容错。文中描述了此方法的基本模型、系统结构和基于CORBA的原型实现。

This paper presents a novel approach to support fault tolerance in component-based distributed software through dynamic reconfiguration. Using the graph-oriented programming (GOP) model, the whole software architecture is specified by a logical graph. Dynamic reconfiguration is implemented by executing a set of operations predefined over the graph. The approach supports fault tolerance by dynamic reconfiguration upon detection of faults. We describe its basic model, system architecture and prototype implementation based on CORBA.'
