Abstract

In this paper, we are interested in the Optical Multi-Band Network Design. This problem consists, given the physical layer of an optical network and a set of traffic demands, in designing a virtual layer and grooming the traffic demands on virtual links called subbands, then to determine the number of subbands and the wavelength to assign for each subband of the virtual layer. We first propose a node-arcs, and arc-paths integer linear programming formulations for the problem, then we describe the column generation procedure for solving the linear relaxation of the 0-1 arc-paths formulations.
