Abstract

The present invention relates to a domain name resolution system disaster recovery construction method, which comprises the following steps: synchronizing the data of the target cluster providing DNS service to the disaster recovery cluster in real time, the data includes cache data for providing domain name resolution basis; receiving A domain name resolution request, using the cached data to perform domain name resolution in response to the domain name resolution request; responding to the domain name resolution request with a domain name resolution result. In addition, the invention also provides a domain name resolution system disaster recovery construction device. The construction method of the present invention can construct a disaster recovery system applicable to the existing domain name service system, and can temporarily and effectively play the role of domain name resolution service when the existing domain name service system or the network it depends on is paralyzed.

Description

technical field [0001] The invention relates to Internet security technology, and relates to a domain name resolution system disaster recovery construction method and device. 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 data synchronization m...
