  Abstract

A new wavelength assignment algorit hm has been proposed to route optical paths of interconnected WDM(Wavelength-Division Multiplexing) ring networks. The proposed algorithm assigns wavelengths on the optical paths analytically to satisfy a full-mesh connectivity between the nodes and uses a minimal number of wavelength for a given network configuration. The algorithm consists of three main procedures. It divedes the nodes into several groups at first, generates matrices, and finally assigns values into the entries of the matrices. The matrices describe the wavelengths assigned, add and drop nodes, the number of hops, and signals propagation directions. We examined the algorithm in the several exemplary net works and confirmed that we can use the analytic algorithm for path routing in WDM networks with complex configurations.
