The example embodiment determines a path through the network for optical wavelengths to be supported by the links represented in 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 {HEAD ~ an acceptable integrity} of the optical wavelengths to a path establishment module to establish the path through {TAIL ~ the optical network}
