Layered-graph Algorithm of Static Routing and Wavelength Assignment for Optical Networks

Han Hu

Abstract

This paper puts forward a heuristic algorithm of Routing and Wavelength Assignment (RWA), which unifies the routing and wavelength assignment subproblems. Through a new Layergraph (LG) algorithm and limitative coefficientk,the routing and wavelength assignment of all optical networks can be optimized, which would make the required wavelengths the least for setting up opticalconnects. Finally the performance is studied by using some optical networks examples. It proves that this LG algorithm performs better than the existing ones. 
