Primary and backup switching method and device, related electronic equipment and readable storage medium

Abstract

The embodiment of the invention provides a primary and backup switching method, a primary and backup switching device, related electronic equipment and a readable storage medium, applied to the technical field of wireless communication. The method comprises the steps of receiving address information of a primary access controller (AC) associated with an access point (AP) sent by the AP, wherein the address information of the primary AC is sent by the AP after separately building communication tunnels with the primacy AC and the backup AC; if the condition that the AP is switched to the backupAC from the primary AC, sending the address information of the primary AC to the AP, thus allowing the AP to detect whether the primary AC is returned to normal operation according to the address information of the primary AC, and when the condition that the primary AC is returned to normal operation is detected, rebuilding the communication tunnel with the primary AC, and switching to the primaryAC from the backup AC. According to the method, the device, the equipment and the medium provided by the embodiment of the invention, when the AP performs primary and backup switching, the AP can bereturned to the original primary AC, so that the AP associated with the primary AC is accordant with that before switching, and the problem that the load of the individual AC is overhigh after switching is avoided.

Description

technical field [0001] The present application relates to the technical field of wireless communication, and in particular to a master-standby switching method, device, related electronic equipment and readable storage medium. Background technique [0002] With the gradual upgrade of wireless hotspot construction, the number of APs (Access Point, Access Point) access is increasing, how to ensure the reliability of wireless access becomes crucial. In the centralized forwarding mode, the AC (Access Controller, access controller) undertakes the state maintenance and data forwarding work of a large number of APs. The failure of the AC will cause the service interruption of the wireless network. In the N+1 backup network (where N refers to N active ACs, and 1 refers to one backup AC), APs can be provided with two Link, that is, the AP establishes CAPWAP (Control And Provisioning of Wireless Access Points, Wireless Access Point Control and Provisioning Protocol) tunnels with the ...

Problems solved by technology

However, when the AP models associated with different active ACs overlap, there can be multiple active ACs associated with the same type of AP, and AP groups cannot be set for different types of APs. After the active / standby switchover, the AP distribution associated with the active AC will be inconsistent with that before the switchback
