Paper Abstract

In this paper, we consider the optimal design of all-optical networks based on wavelength-division multiplexing (WDM). Given a static channel demand, we present a new method to minimize the numbers of optical fibers on each link which are at least necessary to transmit the demanded traffic via the network. In order to minimize the necessary number of fibers, the well known problem of routing and wavelength assignment (RWA) has to be solved, too. Therefore, we present a new approach to the solution of the RWA problem, which bases on the combination of a genetic algorithm and a simple heuristic. The efficiency of our new method is finally demonstrated by the application to a European backbone network.
