An exemplary method and optical network that provide optical network restoration using refreshed state tables are disclosed. The exemplary method for recovering from a failure in an optical network using refreshed switch state tables includes generating and storing connection information in switch state tables of associated optical switches that define optical link connections to be made in the event of a failure, monitoring whether a failure has occurred, and refreshing the switch state tables by continuing to generate and store connection information in the plurality of switch state tables that are associated with the plurality of optical switches of the optical network until the failure in the optical network is detected. Once the failure is detected, optical switching is automatically performed in the optical switches based on the lookup table connection information in the switch state tables that are associated with the optical switches. The exemplary method may then include determining whether any of the telecommunications traffic in the optical links of the optical network was not restored due to the optical switching that was automatically performed. |
