Embodiment Construction

[0073] As described in the background technology, the existing wireless controller hot backup technology is to establish a backup channel between the active wireless controller and send service information from the active wireless controller to the standby wireless controller, so as to realize the wireless controller Backup of business information in . However, such a technology needs to establish a separate backup channel, which increases the consumption of system resources.

[0074] Therefore, the present invention hopes to use the existing communication mechanism between the AC and the AP to realize the hot backup function of the AC without developing a dedicated communication channel between AC devices.

[0075] To achieve the above purpose, the present invention provides a method for backing up service information of wireless controllers, which is applied to a system including one active wireless controller, at least one standby wireless controller and at least one wirele...

Abstract

The invention discloses a wireless controller configuration information backup method and equipment, which are applied to a system comprising an active wireless controller, at least one standby wireless controller and at least one wireless access point, wherein the active wireless controller is configured with the address information of the at least one standby wireless controller, and active communication linkage is established between the at least one wireless access point and the active wireless controller. By the method, the wireless access point in the system maintains communication linkage with the active-standby wireless controllers simultaneously and realizes switch when failure occurs so as to guarantee the continuous implementation of services. With the invention, the backup of the configuration resources of the wireless controller can be realized under the condition that the wireless controller does not need to independently establish backup channels among the wireless controllers.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a method and equipment for backing up service information of a wireless controller. Background technique [0002] A wireless access point (Access Point, AP) is currently a commonly used device when building a small wireless local area network. The AP is equivalent to a bridge connecting the wired network and the wireless network. Its main function is to connect various wireless network clients together, and then connect the wireless network to the Ethernet. According to the differences in the functions integrated by the AP itself, the existing technology is divided into a FAT AP networking structure and an AC+FIT AP networking structure. [0003] Among them, the FAT AP networking structure is an existing common networking structure, and its schematic diagram is as follows figure 1 shown. [0004] In this FAT AP networking mode, the AP is connected to the wired network t...
