The AP will periodically send Discovery Request messages to detect the status of the original main link. When the link is restored, the AP detects that the priority of the link is higher than the priority of the main link currently in use and triggers a fallback. In order to avoid frequent switching caused by network shocks, after waiting for 6 Echo cycles, the AC is notified to perform active and standby simultaneous switching, and at the same time, the AP sends the STA’s data service to the newly upgraded AC.
