Abstract

The invention provides a DNS downtime detection switching method and system based on cloud detection. The method includes the steps of setting at least three detection nodes which belong to different IP sections, deploying independent detection software on each detection node, conducting cloud detection on a target analysis IP address through the detection software, sending the result of the cloud detection to downtime judgment software, conducting analysis through the downtime judgment software according to the result of cloud detection, making judgment according to a downtime judgment algorithm, and if judging out server downtime corresponding to the target analysis IP address, switching to another target analysis IP address server. According to the technical scheme, the more effective downtime detection switching function can be achieved.

Description

technical field [0001] The invention belongs to the technical field of computer communication, in particular to a cloud-based detection [0002] The DNS downtime detection switching method and system of the present invention. Background technique [0003] The Domain Name System (DNS for short) is mainly used to complete the mapping from domain names to Internet Protocol (IP) addresses and the resolution of other Internet resources. It is an important infrastructure in today's Internet. [0004] DNS downtime detection means that when the domain name resolves an IP address at the same time, it can detect the downtime of the servers added to the downtime detection queue. When the target server is found to be down, the software system automatically resolves the domain name to the normal server . To ensure that the website can be accessed normally. Downtime detection must have 2 or more server IPs to ensure that a server can be switched to other server IPs when a server is dow...
