Main equipment election method and device and machine readable storage medium

Abstract

The invention discloses a main equipment election method and device and a machine readable storage medium, which are used for reducing the influence of a VRRP protocol on service continuity in the main equipment election process. According to the invention, after the main equipment receives VRRP notification messages sent by other main equipment, the priorities, the key resource weights and the IPaddresses carried by the notification messages are compared, the main equipment election is carried out based on the priority sequence, and the new main equipment is determined. According to the method, the decision condition for judging the key resource weight on the main equipment is added in the main equipment election rule, and the main equipment state of the main equipment with the large keyresource weight is maintained preferentially, so that the influence on the current ongoing service is reduced, and the service continuity of client hosts or users is ensured as much as possible.

Description

technical field [0001] The present invention relates to the field of communication technology, and in particular to a master device election method, device and machine-readable storage medium. Background technique [0002] All hosts in the same network segment are usually configured with the same default gateway. Messages sent by the hosts in this network segment to other network segments will be forwarded through the default gateway, so as to realize the communication between the host and the external network. When the default gateway fails, all hosts in this network segment will not be able to communicate with the external network. In order to avoid this situation, a group of routers that can assume the gateway function can be added to the backup group by using the Virtual Router Redundancy Protocol (VRRP), forming a virtual router, and specifying Virtual IP address, the router group that forms the virtual router includes the primary router and the backup router. When the...

Problems solved by technology

[0009] In the above VRRP application scenario, if the notification message transmission between the backup device and the master device fails, there may be multiple master devices at the same time, and these multiple master devices may provide external services, and when the notification message is transmitted After the fault is eliminated, re-election of the master master device by applying the master master device election rules defined in the aforementioned VRRP protocol may cause a large number of business services provided by one or some master devices to be interrupted, causing customer business abnormalities, and reducing system reliability and reliability. effectiveness
