Abstract
Techniques are provided for using light path priority of service information in an optical network. At a node in the optical network, priority of service information is stored for a plurality of light paths used in the optical network. The node serves traffic in the optical network using the plurality of light paths based on the priority of service information. These techniques provide for prioritizing light paths (wavelengths) for scenarios such as restoration, congestion and resource contention.
