1. A method for configuring a communication network, comprising:
obtaining a set of multiple layer graphs for the communication network that includes nodes and communication links, each layer graph corresponding to one of a set of frequency slots associated with the communication network and including:
layer graph edges associated with ones of the communications links for which the frequency slot is available; and
layer graph vertices associated with ones of the nodes, the layer graph vertices including a source layer graph vertex and a terminal layer graph vertex for a demand associated with the communication network;
selecting the demand, from among a set of demands associated with the communication network, based on a frequency slot width or transceiver associated with the demand;
determining a path for the demand using the set of the multiple layer graphs, the path connecting one of the source layer graph vertices to one of the terminal layer graph vertices; and
configuring the communication network to satisfy the demand using the determined path.
