Method to Ensure a Feasible Wavelength Assignment within the Routing-Only Problem for Transparent WDM Networks
In transparent WDM networks, the optimization problem contains the routing and the wavelength assignment problem, which leads to a high computational complexity. We suggest a set of constraints which either ensures a wavelength assignment solution for a calculated routing, or tests a preprocessed routing for a feasible wavelength assignment. First case studies show a remarkable speed up in calculation time as well as an evaluation of the optimality of the planning solution.
