Abstract

The invention relates to a DNS (domain name server) disaster tolerance system islanding response automatic switching method and device. The method comprises the following steps that operation data of a cluster providing DNS service is received and collected; the operation data is calculated according to preset configuration information for forming the operation state judging result of an DNS service cluster; when the judging result represents an abnormal operation state, a target address for providing the DNS service is modified into a network address of a disaster tolerance system; when the judging result represents a normal operation state, the target address for providing the DNS service is modified to be pointed to the original target address. The DNS disaster tolerance system islanding response automatic switching method and device provided by the invention have the advantages that the operation state of the traditional DNS service cluster can be fast recognized, and when the existing DNS system or a reliant network thereof generates paralysis, the disaster tolerance system can be used for building an islanding response mode for ensuring that an Internet user can use the effective domain name resolution service, so that the Internet is safer.

Description

technical field [0001] The invention relates to Internet security technology, and relates to a method and a device for automatically switching island responses of a DNS disaster recovery system. Background technique [0002] The disaster recovery system is a technology for backup and disaster recovery of business systems composed of network clusters, and is widely used in Internet service clusters. Usually, Internet services are provided by the normal operation of the business system, and the disaster recovery system performs real-time backup and fault detection on the normal operation of the business system, and after the business system fails or is attacked, the disaster recovery system can be used intelligently The system replaces the original business system and opens the same service to Internet users. [0003] A disaster recovery system usually includes several major management logics of data synchronization, fault detection and business switching. Among them, the da...
