The example embodiment determines a path through the network for optical wavelengths to be supported by {HEAD ~ the links} represented in {TAIL ~ the database} as a function of evaluating optical signal characteristics at each link along a possible path using the advertised optical signal capabilities and provides a selected path meeting an acceptable integrity of the optical wavelengths to a path establishment module to establish the path through the optical network
