A Forward-Backward Optical Wavelength Path Establishment Scheme with Low Blocking Probability in WDM Networks
—we study dynamic routing and wavelength assignment scheme when there are any available wavelengths on a route in the wavelength-routed networks. An optical wavelength path reque...

Heuristic and optimal techniques for light-trail assignment in optical ring WDM networks
In this paper we address the problem of constrained optimization (ILP formulation) and propose a set of heuristic algorithms for assigning light-trails [1–4,7,10] to WDM ring ne...
