Method and system for implementing website disaster-tolerating and error-tolerating operation

Abstract

The invention discloses a method and a device for realizing disaster and fault tolerance operation of a website, which have the capability of tolerating disasters and faults at real time during the operation of the website. The invention adopts the technical proposal that the system comprises target websites, a disaster tolerance backup center used to store and operate the emergency backup websites of the target websites, and a monitoring and dispatching centre which operates independently, identifies the faults and errors of the target websites and sends dispatching orders when faults occur or the faults are recovered. A DNS management center realizes the switching between the target websites and the emergency backup websites, realizes the user analysis requirements to the domain names according to the IP addresses of the emergency backup websites in the domain name selections when receiving the dispatching orders to switch to the emergency backup websites, and realizes the user analysis requirements to the domain names according to the IP addresses of the target websites in the domain name selections when receiving the dispatching orders to switch to the target websites. The method and the device are applicable for network service.

Description

technical field [0001] The invention relates to the technology of safe operation of the website, in particular to a method and system for realizing disaster recovery and fault tolerance operation of the website. Background technique [0002] The operation of a website requires the support of many operators, software and hardware facilities, various communication protocols, technology and personnel, so there are various factors for failures, but for some key department websites, due to the release Information has basic requirements such as authority, seriousness, uniqueness, and non-tampering. At the same time, the continuous availability of these websites is also the focus of attention from all walks of life. For these crucial websites, how to achieve disaster recovery and fault tolerance? Long-term continuous operation under the premise, that is, emergency protection, has become a thorny problem encountered in the operation of many websites. The main unfavorable technical ...

AI Technical Summary

Problems solved by technology

[0003] 1) The working mode of Domain Name System (DNS) is asynchronous, multi-level caching, redirection and distribution mechanism, which determines that a website will have a lot of trouble when switching external servers with different IPs. long delay

[0004] 2) Website faults are quite complex and diverse in terms of form, cause, and affected area, which determines that only some simple test methods (such as testing link continuity and ping, understanding equipment load, etc.) cannot judge such as data Errors, content tampering and other complex issues
