Patent ID: 8775869

Claim:
A device for coordinating an Automatic Protection Switching (APS) operation and a recovery operation, comprising a hardware processor, which executes a working channel detection unit, a protection protocol unit and a recovery protocol unit, wherein: the working channel detection unit is configured to monitor working channel failures of services and to report a working channel alarm to the protection protocol unit and the recovery protocol unit in case of failure occurring in a working channel; the protection protocol unit is configured to receive the working channel alarm and to determine whether a recovery operation needs to be started up immediately according to the working channel alarm, wherein if yes, it notifies the recovery protocol unit to start up the recovery operation immediately, otherwise it starts up an Automatic Protection Switching (APS) operation; and the recovery protocol unit is configured to receive the working channel alarm and the notification of immediately starting up the recovery operation, wherein it starts up the recovery operation when the notification of immediately starting up the recovery operation is received, or when the working channel alarm received still exists even if a predetermined time limit expires, wherein the recovery operation does not pre-configure a protection channel, and in the case of fault occurring in the working channel, the recovery operation recalculates a new channel for services in idle resources of current network, and the Automatic Protection Switching operation pre-configures a protection channel, and in the case of fault occurring in the working channel, the Automatic Protection Switching operation switches services to the protection channel.
