Abstract
Embodiments of the disclosure are directed to optimizing routing and wavelength assignment in a network. An embodiment determines a routing assignment for a network, wherein the routing assignment is determined using a decongestion cost-based function; and determines a wavelength assignment for the network based on vector difference. The determination of the wavelength assignment comprises spanning the network for a path; calculating a weighted correlation function for at least one length in the network; storing the weighted correlation; and determining if a next path exists. If a next path is found, spanning for a next path in the network, and if a next path is not found, returning the stored correlation.
