Device and method for coordinating automatic protection switching operation and recovery operation
Abstract:
The present invention relates to a device and a method for coordinating an APS operation and a recovery operation. The device includes a working channel detection unit, a protection channel detection unit, a protection protocol unit and a recovery protocol unit. The method comprises: when the working channel of current service fails, the working channel detection unit reporting a working channel alarm to the protection protocol unit and a recovery protocol unit of current node; the recovery protocol unit starting up a timer after receiving the working channel alarm, and the protection protocol unit determining whether the recovery operation needs to be started up immediately after receiving the working channel alarm, and if yes, the protection protocol unit notifying the recovery protocol unit to start up the recovery operation immediately; the recovery protocol unit starting up the recovery operation immediately after receiving the notification. The present invention reduces the damage time of the service in the case of the APS function failure.
