摘要
介绍了高可用性冗余集群系统的一些关键技术,提出了一种基于任务表的自适应容错算法,对算法的设计思想和具体实现进行了详细阐述。最后建立了系统随机Petri-net模型,对系统进行可信性分析,经计算分析表明系统满足实际高可用性要求。
Some key technologies for deploying high availability cluster system were discussed in this paper.An adaptive fault-tolerance method based on task table was presented.The designing idea of the adaptive fault-tolerance algorithm and the implementation of the algorithm were described in detail.Finally,the dependability model with Petri-net was also presented.According to the dependability analysis of the high availability cluster,it shows that the cluster system in this paper has high availability to be used ...
