摘　　要：本文提出了一种实时异地灾备系统的失效检测方法。失效检测分级部署,分为主机级检测和网络级检测。各级别的检测又分为失效检测、失效决策和失效处理三个模块。其中,网络级检测采用了自适应的算法,综合考虑了网络延时和丢包的情况。A failure detection method for real-time disaster recovery systems is proposed. The failure detection is hierarchically arranged, and it is divided into host-detection and network-detection. Both hierarchies are composed of failure detection, failure decision and failure processing. Considering the network delay and the package lost, the network-detection adopts a kind of self-adapted algorithm.
