Method, device, equipment and storage medium for preventing service interruption

Abstract

The invention discloses a method and device for preventing service interruption, an equipment and a storage medium, and the method comprises the steps of building a first communication tunnel with a standby center AC, and then building a second communication tunnel with the main center AC if the recovery of the main center AC is detected, and disconnecting the first communication tunnel; if it ismonitored that the table item information of the AP accessed to the local AC is not successfully transmitted to the standby center AC, determining the reason of table item information transmission failure; and when the determined reason is that the local AC actively disconnects the first communication tunnel, keeping communication connection between APs corresponding to the table entry information. According to the method, whether the communication connection with the AP is disconnected or not is determined according to the reason of the table entry information transmission failure. For the transmission failure caused by the fact that the local AC actively disconnects the first communication tunnel with the standby center AC, the communication connection with the corresponding AP is not disconnected, when the local AC is switched back to the main center AC, the AP is prevented from being kicked off, and the service interruption of the AP is effectively prevented.

Description

technical field [0001] The present application relates to network communication technology, in particular to a method, device, equipment and storage medium for preventing service interruption. Background technique [0002] WLAN (Wireless Local Area Networks, wireless local area network) layered architecture includes central AC (Access Controller, access controller), local AC and AP (Access Point, wireless access point), central AC is responsible for managing the entire wireless network, local AC Responsible for accessing APs and forwarding data traffic. [0003] Currently, two central ACs are usually deployed in the WLAN layered architecture, that is, the main central AC and the standby central AC. When the local AC goes online for the first time, it connects to the main central AC. When the main central AC fails, the local AC switches to the standby central AC, and transmits the entry information of the connected APs to the standby central AC. After the main center AC re...

AI Technical Summary

Problems solved by technology

If the main center AC recovers during this period of time, and the local AC disconnects the communication tunnel with the backup center AC, the table entry information of some APs has not been transmitted to the backup center AC. At this time, the local AC in related technologies will Disconnect the communication connection with this part of the AP, resulting in the inability of this part of the AP to carry out normal business communication
