Claim 10:
11. 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 and send the OPS request to one or more transponders associated with each of the originating node and terminating node.
