Abstract

Abstract:

The routing and wavelength assignment (RWA) problem in WDM(wavelength division multplexing) all optical networks was studied. A novel adaptive routing and wavelength assignment algorithm, the minimum path weight first (MPWF), was proposed. Simulation result shows that compared with previously proposed RWA algorithms, the MPWF algorithm achieves better performance under uniform and non-uniform traffic models.

Key words: routing and wavelength assignment, wavelength division multiplexing, wavelength routing, all optical network
