Abstract

This paper is a study of routing in optical WDM grid networks, these being chosen since they represent good idealizations of less regular networks, suggest hypotheses about them, can be used for local area and computer networks, and are analytically tractable. Due to performance, cost, and physical effects in the fibers, it will be necessary to have several fibers between each pari of connected nodes supporting some small number of wavelengths on each. This is modeled analytically and compared with simulation for a variety of cases. It is shown that the simplified analytical routing compares well with the heuristic simulation algorithm, and that when multiple fiber links are used, wavelength conversion offers little reduction in network requirements.
