【摘要】 本文提出了一个容灾抗毁系统体系结构。对位于该体系结构不同层次的典型容灾技术进行了阐述,具体讨论了本地容灾、数据容灾、网络容灾、服务容灾技术的工作原理及各自特点。建立了一个容灾抗毁系统模型,并给出了一个非专线的远程容灾系统的实现。更多还原

【Abstract】 An architecture of disaster tolerant system is proposed.Some typical disaster tolerant technologies at different levels of the architecture are expounded.Specifically,the implement principle and features of the technologies are discussed, including local disaster tolerance,data disaster tolerance,network disaster tolerance and service disaster tolerance.The model of disaster tolerant system is introduced.Finally,this paper gives the realization of a remote disaster tolerant system based on private network channel.更多还原
