Abstract

The embodiment of the invention discloses a distributed network system fault-tolerance method, a distributed network system fault-tolerance device, and a fault-tolerant distributed network system. When a load balance unit in an area breaks down or rear-end service unit clusters corresponding to the load balance unit all break down, a domain name system (DNS) can automatically migrate a service request that originally belongs to the area to other areas. When the service request that belongs to one area is sent to the other area, if the load balance unit of the original area breaks down, but the rear-end service unit operated normally exists in the original area, the service request of a client is forwarded to the rear-end service unit of the original area; if the load balance unit of the original area and rear-end service unit clusters all break down, the service request is sent to the rear-end service unit of the other area; and if the load balance unit of the original area and rear-end service unit clusters all operate normally, the service request is redirected to the original area for processing. Therefore, the distributed system can be rapidly recovered to normal operation from the fault.

Description

technical field [0001] The invention relates to the field of network technology, in particular to a fault-tolerant method and device for a distributed network system and a fault-tolerant distributed network system. Background technique [0002] Usually distributed network systems such as figure 1 As shown, it includes DNS (Domain Name System, Domain Name System, a distributed database that maps domain names and IP addresses on the Internet), load balancing unit, back-end processing unit cluster (multiple back-end processing units) and back-end running detection unit. A DNS corresponds to one or more load balancing units, and each load balancing unit corresponds to multiple back-end processing unit clusters. A load balancing unit and its corresponding back-end processing unit clusters and back-end operation detection devices can be called a data center. Among them, after DNS receives the service request sent by the user's client through the network, it converts the URL (Un...
