| 摘 要： | 提出了一种面向事务处理的容错计算机体系结构，设计了基于三模冗余的仲裁器和仲裁算法。在集群中，利用中心结点故障检测机制，采用仲裁器得到了一个逻辑上高可靠的管理态结点，通过该结点可以实现系统快速故障诊断和故障恢复。实验结果表明：节点间故障检测时间小于2s，故障节点切换时间小于5s，该系统的故障检测、故障节点切换可以满足事务处理系统对可靠性的要求。

| Abstract: | A fault tolerant computer architecture for transaction processing was presented and an arbitration module and an arbi- tration algorithm were designed based on a triple modular redundancy.Using the center-node detection mechanism,a log- ically reliable management node was implemented by using the arbitration module in a cluster system,through which the system's rapid fault diagnosid and fault recovery can be accomplished.The experimental result showsed that the fault de- tection time was less than 2 seconds... |
