— This paper proposes optical wavelength division multiplexed (WDM) networks with limited wavelength conversion that can efficiently support lightpaths (connections) between nod...
— We study the complexity of a spectrum of design problems for optical networks in order to carry a set of demands. Under wavelength division multiplexing (WDM) technology, deman...
Abstract--The traffic grooming problem is of high practical importance in emerging wide-area wavelength division multiplexing (WDM) optical networks, yet it is intractable for any ...
Abstract— Wavelength converters simplify the wavelength assignment problem in virtual topology design in optical networks and increase the utilization of the fiber bandwidth. Ho...
Abstract--This paper addresses multicast routing in circuitswitched multihop optical networks employing wavelength-division multiplexing. We consider a model in which multicast com...
