Prioritizing Optical Routes for Restoration Based on Failure Impact on an IP Layer

A method for real-time restoration in a multi-layer network having an optical layer and a higher layer, the method comprising steps of:

• modeling each of a plurality of potential optical failures in the optical layer, including identifying corresponding disruption in the higher layer;
• deriving a set of candidate optical restoration paths for each potential optical failure and ordering those paths based on the identified disruption;
• and
• storing each ordered set of candidate optical restoration paths for real-time use during any actual optical failure.

A non-transitory computer-readable medium for real-time restoration in a multi-layer network having an optical layer and a higher layer, the non-transitory computer-readable medium storing instructions that, when executed, cause one or more processors to perform steps of:

• modeling each of a plurality of potential optical failures in the optical layer, including identifying corresponding disruption in the higher layer;
• deriving a set of candidate optical restoration paths for each potential optical failure and ordering those paths based on the identified disruption;
• and
• storing each ordered set of candidate optical restoration paths for real-time use during any actual optical failure.
