Abstract :
This letter proposes to use the path state approach for updating the Traffic Engineering Database (TED) of the Path Computation Element (PCE) in GMPLS controlled Wavelength Switched Optical Networks (WSONs). The proposed solution reduces both the lightpath blocking probability and the control plane load with respect to conventional updating schemes based on the link state approach.
