Problems solved by technology

In this case, if the master device handles too many network services, but the master device does not detect the link failure or the UP / DOWN state of the interface, it will not switch over the master and backup devices at this time, which will result in low network service processing efficiency. question

Embodiment Construction

[0028] The following will clearly and completely describe the technical solutions in the embodiments of the application with reference to the drawings in the embodiments of the application. Apparently, the described embodiments are only some of the embodiments of the application, not all of them. Based on the embodiments in this application, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of this application.

[0029] At present, in the dual-deployment network that adopts the master-standby mode, the master device monitors the link status and the status of the monitoring interface in real time. When a link failure between the peer device and the master When the interface of the end device is in the UP / DOWN state, it will switch itself to the backup device and send a switch message to the original device; after receiving the switch message, the original device will switch itself to the maste...

Abstract

The embodiment of the invention provides a master and backup device switching method and device. The method is applied to a first device. The first device is a backup device. The method comprises thesteps of sending a first detection message to a second device, wherein the second device is a master device; switching the first device to the master device if a first response message fed back by thesecond device according to the first detection message is not received within the maximum response duration after the first detection message is sent; and switching the first device to the master device if the first response message is received within the maximum response duration after the first detection message is sent, and the first response message is not received within the preset durationafter the first detection message is sent and / or a resource utilization rate of the second device contained in the first response message is greater than a resource threshold, and sending a first switching message to the second device, thereby switching the second device to the backup device, wherein the preset duration is smaller than the maximum response duration. Through application of the embodiment of the invention, the network business processing efficiency is improved.

Description

technical field [0001] The present application relates to the technical field of communications, and in particular to a method and device for switching master and backup equipment. Background technique [0002] In order to ensure the availability of the network, the dual-machine deployment in active and standby mode is often used in network deployment, such as figure 1 The shown networking includes a device 100 and a device 200, wherein the device 100 is a master device, and the device 200 is a backup device. [0003] At this time, the device 100 is responsible for network services such as detection and forwarding of traffic from the peer device (including user-side devices and network-side devices). When the device 100 detects a link failure between the peer device and the device 100, or When it is detected that the interface of the device 100 or the peer device is in the UP / DOWN state, the device 100 switches itself to the backup device and sends a switch message to the d...
