Abstract
To facilitate routing and wavelength assignment (RWA) in an optical communications network having a given topology of associated nodes and links, a set of system characteristics associated with operating the optical communications network may be determined. Different sets of values may be selected for one or more parameters of an RWA algorithm defined for operating a set of services on the optical communications network, and associated sets of routes and wavelengths that may be assigned to the set of services via the RWA algorithm in accordance with the different sets of values and the set of system characteristics may be determined. The different sets of routes and wavelengths may be compared based on one or more fitness criteria and thereby selected between. A path computation engine of the optical communications network may then be provisioned with the selected set of values for the one or more parameters.
