摘要
高可用性集群的设计思想就是要最大限度地减少服务中断时间,目的是在系统出现某些故障的情况下,仍能继续对外提供服务。在分析了网络互连的几种常用拓扑结构优缺点的基础上,提出了一种适用于高可用性集群的拓扑结构——分层双环网络,并对它的高可用性和可靠性进行了分析。
The designed idea of high availability cluster is shortening the service interrupted time mostly and it＇s purpose is it can still offer service when some failure occurs in the system. Based on analysis of several in common use topology＇s advantages and disadvantages, a kind of topology-level double ring network which is fit for high availability cluster is put forward and it＇s high availability and reliability is analysed.
