Abstract
In accordance with embodiments of the present disclosure, a method may include for each particular working demand in a communication network, calculating a dedicated backup path for a working path of the particular working demand such that each particular backup path does not include links present in the working path. The method may also include, for each particular working demand: (i) assigning to the backup path a wavelength associated with the particular working demand; and (ii) assign to the backup path a transponder at each of the source and destination of the backup path associated with the wavelength; such that the backup path for at least one particular working demand is assigned a transponder that is also assigned to the backup path for at least one other particular working demand.
