Title: PHOTONIC-LAYER AWARE PATH COMPUTATION ELEMENT
Abstract:
A network controller in a control plane and a method for selecting a connection for a wavelength channel from a plurality of connection candidates in a communications network are disclosed. The network controller comprises a modeling module and a routing engine. The modeling module obtains information from a physical element in the network, related to an estimated time for the element to establish each connection candidate therethrough for the wavelength channel. The routing engine selects the connection taking into account the estimated time associated with each connection candidate.
