Abstract
A network management system can be configured to identify routes for satisfying a set of demands on a communications network using layer graph(s). The network management system can generate the layer graph(s) using a network graph that represents the optical communication network and an associated sets of available frequency slots. The network management system can iteratively identify candidate path(s) on the layer graph(s) that correspond to each of the demands and determine a cost for each candidate path. The cost for a candidate path can depend on a set of available edges affected by the selection of the candidate path. In each iteration, the network management system can select the lowest cost candidate path, update the network graph to reflect the selection of this candidate path, update the layer graph(s) based on the updating of the network graph, and update the candidate paths for the remaining demands as needed.
