Routing and wavelength assignment in WDM all-opticalnetworks

Kyung-Sik Lee, Sungsoo Park, Kyung-Il Choe, Cheehang Park

Abstract

A new mathematical formulation of the routing and wavelength assignment in wavelength division multiplexing (WDM) all-optical networks is proposed, which yields tight linear programming lower bounds on the wavelength requirements both theoretically and computationally. An efficient procedure for computing lower bounds is also presented together with preliminary computational results.
