Wavelength Assignment for All-to-All Broadcast in Wavelength Division Multiplexing Optical Ring

Abstract

A novel wavelength assignment method is proposed for a bidirectional WDM ring network and the minimum number of wavelengths required to support all-to-all broadcast is determined. The new method can assign each wavelength directly and simultaneously to a group of non-overlapping connections on an N-node ring without the aid of any table or matrix. The presented wavelength assignment method is much faster than other direct methods with explicit formulas previously reported for WDM ring network.
