Problems solved by technology

[0003] In the WDM monitoring system of the prior art, the main control device exchanges information with the terminal system through a fixed routing device. Since the routing device is fixed, when it fails to work normally, the main control device and the terminal system will not be able to exchange information. Interaction, the entire network element will be disconnected, and the protection control channel will also be blocked.

Embodiment Construction

[0022] The main realization principles, specific implementation modes and corresponding beneficial effects of the technical solutions of the embodiments of the present invention will be described in detail below in conjunction with each accompanying drawing.

[0023] Such as figure 1 As shown, a redundant backup switching method provided by an embodiment of the present invention, the method includes the following steps:

[0024] Step 101, calculating the priority of the backup routing device according to the priority value corresponding to the parameter of the backup routing device, the weight value corresponding to the parameter, and the device priority value configured by the user;

[0025] Step 102, when no message is detected from the primary routing device within a predetermined time, switch the backup routing device with the highest priority to the primary routing device.

[0026] After the redundant backup switching device is started, a virtual IP address is configured...

Abstract

The embodiment of the invention relates to the wireless communication technology, in particular to a redundancy backup swap method, a redundancy backup swap device and a redundancy backup swap system, which are used for realizing quick and accurate swap of master and standby routing equipment and improving overall fault-tolerant capability of the routing equipment. The method comprises the following steps of: calculating the priority of the standby routing equipment according to priority values corresponding to parameters of the standby routing equipment, weight values corresponding to the parameters and an equipment priority value configured by a user; and when a message sent by the master routing equipment is not detected in preset time, swapping the standby routing equipment with the highest priority into the master routing equipment.

Description

technical field [0001] The invention relates to wireless communication technology, in particular to a redundant backup switching method, device and system. Background technique [0002] Resilience and redundancy have become key features in today's LANs. To this end, IETF (Internet Engineering Task Force, Network Engineering Task Force) has formulated VRRP (Virtual Router Redundancy Protocol, Virtual Router Redundancy Protocol), which is applied to the Layer 3 switch on the statically configured default gateway. The default gateway for WAN access or end systems accessing other LAN domains provides faster and more efficient redundant fault tolerance. [0003] In the WDM monitoring system of the prior art, the main control device exchanges information with the terminal system through a fixed routing device. Since the routing device is fixed, when it fails to work normally, the main control device and the terminal system will not be able to exchange information. Interaction, t...
