Abstract

The invention discloses a method and a system for implementing switching of a master server and a standby server. The method comprises the following steps that a gateway broadcasts a first ARP (Address Resolution Protocol) request when the standby server monitors that the master server cannot respond to a second ARP request; the standby server which has the same IP (Internet Protocol) address as the malfunctioning master server receives the first ARP request, an MAC (Media Access Control) address of the standby server is transmitted to the gateway through a standby exchange and a host exchange. According to the method and the system, the fault condition of the master server is monitored by the standby exchange, so that when the master server has a fault and cannot respond to the second ARP request, the standby server corresponding to the master server is started to respond the first ARP request so as to complete mutual switching of the master server and the standby server. On the one hand, compatibility of service application of the present network is guaranteed; on the other hand, switching of the master server and the standby server is simply implemented, and a cluster function of the server is not needed. Therefore, the investment and the operation of the existing network equipment are effectively protected, and safer and faster data storage assurance is brought to enterprises.

Description

technical field [0001] The invention relates to a backup technology, in particular to a method and a system for realizing switchover between active and standby servers. Background technique [0002] At present, in the commonly used active and standby solutions, multiple servers are generally required to form a cluster server architecture, such as figure 1 As shown, for example, server S, server S', and server S" serve as a cluster. It is assumed that server S serves as the master server, and server S' and server S" serve as standby cluster servers. The standby cluster servers can be sorted by priority in advance. When the main server fails in a disaster, the switch will start the standby server according to the preset priority order (only one server is active at the same time). Both the master server and the slave server are installed with cluster software to provide a cluster function, and the main function of the cluster software is to perform heartbeat detection between ...
