Abstract
Systems and methods include continuously tracking health of services in an optical network, monitoring how many restoration paths remain accessible to an on-box control plane, and quality of any remaining restoration paths; managing restoration paths installed on the nodes to one or more of remove unavailable restoration paths and add new available restoration paths for any of the services in the optical network; responsive to detecting one or more at-risk services, for the one or more at-risk services, performing computation of new viable restoration paths and a multi-stage policy-based ranking of the new restoration paths for the service; and for the one or more at risk services, pushing the ranked new viable restoration paths to the on-box control plane based on thresholds.
