Claim 12:
13. A non-transitory computer-readable medium configured to store computer logic having instructions that, when executed, enable a processing device to:
perform a first route switching procedure for switching routes between an originating node and a terminating node, the first route switching procedure configured to operate at a first priority level according to an Optical Protection Switching (OPS) policy,
perform a second route switching procedure for switching routes between the originating node and the terminating node, the second route switching procedure configured to operate at a second priority level according to a second OPS policy, wherein the second priority level is higher than the first priority level,
revert back to a home path according to the first route switching procedure after one or more faults, defects, or degradations have been cleared from the home path, and
trigger an OPS request from a Layer 0 Control Plane (L0CP) configured to control at least the originating node and terminating node, wherein the OPS policy includes a parameter for designating an enabled state or a disabled state, the enabled state allowing the L0CP to perform a Control Plane Trigger (CPT) switching action (CPT-OPS) when service is optimized on the home path.
