Abstract
Various embodiments of the present invention are directed to a method for creating and optimizing a DWDM optical fiber network that is configured to service a set of demands associated with a region of interest. The method may include the following steps: 1) determining the highest aggregate demand from a set of demands within a region of interest; 2) determining a total number of lightpaths at discrete line granularities beginning with the highest aggregate demand; 3) determining a DWDM network topology comprised of a plurality of nodes and one or more wavelengths extending between the nodes based on the total number of lightpaths at discrete line granularities; 4) routing lightpaths along the wavelengths extending between the plurality of nodes based at least on predetermined decision criteria; 5) routing demands onto tributaries extending along the lightpaths based at least on predetermined guidelines; 6) calculating a cost associated with the node-related hardware parameters; and 7) outputting the node-related hardware parameters and the associated cost.
