Wireless controller disaster recovery method and system thereof

Abstract

The present invention relates to a disaster recovery method and system of a wireless controller. The method comprises: an active wireless controller synchronizing key service data to a standby wireless controller through a synchronization channel pre-established by the active wireless controller and the standby wireless controller; the standby wireless controller constructing other required related service data according to the received key service data; the active wireless controller and the standby wireless controller detecting whether the active wireless controller side has an exception by using a link detection mechanism, wherein if yes, the standby wireless controller is switched to the active wireless controller to avoid service interruption. The present invention reduces the impact brought by an AP, so that the active wireless controller efficiently and reliably synchronizes data without affecting the service processing, and the standby wireless controller is avoided from being configured again, thereby reducing mistakes, saving the labor cost, avoiding interruption of the wireless service, and improving system reliability.

Description

technical field [0001] The invention relates to the technical field of computer network communication, in particular to an efficient and reliable disaster recovery method and system for a wireless controller. Background technique [0002] In an existing wireless local area network (WLAN) networking, it is generally implemented through a wireless access point (Access Pont, AP) and a wireless controller (Access Controller, AC). In this AC+AP networking mode, "zero configuration" is realized on the AP, and the AC completes functions such as authentication, configuration, and data forwarding of wireless users, and plays a centralized control role to cooperate with the AP to achieve more value-added business. A CAPWAP link can be established and communicated between the AC and the AP through the Controlling and Provisioning of Wireless Access Pont (CAPWAP) protocol. [0003] figure 1 It is a schematic diagram of the existing typical wireless network networking structure, such ...

AI Technical Summary

Problems solved by technology

Although this method is simple to implement, there is still the problem of wireless service interruption. Moreover, as the core control device, the AC needs to synchronize a large amount of service data. Adopting this solution will cause an excessive burden on the active AC and affect service processing.
