摘要
在用于一些关键任务的环境中,由于软件故障而导致的后果是无法容忍的,软件容错技术应运而生而且变得越来越重要。针对分布式嵌入式环境的特点设计了一个容错软件,介绍了容错软件的结构以及各个模块的功能,并分析了节点监测、故障检测和服务迁移等关键技术。
In some key task environment, the aftereffect induced by software fault is out of tolerance. As a consequence, software fault-tolerant technology emerges and gains more and more importance. Aiming at the characteristic of distributed embedded environment, a fault-tolerance software is decigned, the structure of the software and the function of the each module are introduced, and the key technology of node monitor, fault detection and service migration are analyzed.
