Abstract: We present mixed integer linear programming models that are robust in the face of uncertain traffic demands known to lie in a certain polyhedron for the problem of dense wavelength division multiplexing network routing and provisioning at minimal cost. We investigate the solution of the problem in a set of numerical experiments for two models of polyhedral uncertainty: (a) the hose model, (b) a restricted interval uncertainty model. We report the results of these numerical experiments in comparison with an alternative model of robustness due to Kennington et al.

Keywords: Uncertainty modeling, robust DWDM routing and provisioning, hose uncertainty, interval uncertainty, valid inequalities
