Abstract

Various example embodiments are disclosed. According to an example embodiment, a method may include receiving a resource request for optical resources within a wavelength division multiplexed (WDM) optical network; comparing one or more parameters of the resource request to a list of pre-validated paths for the WDM optical network, each pre-validated path identifying an optically feasible label switched path between a source node and a destination node; determining that there is a pre-validated path on the list that matches the one or more parameters of the optical resource request; and sending a message to request a reservation of resources along the matching pre-validated path.
