Paper Abstract

A wavelength scheduling algorithm with limited-range wavelength conversion in OBS network is presented in this paper. Two wavelength conversion policies, First-Fit (FF) and Nearest Wavelength First (NWF) are adopted respectively in this scheduling algorithm. Numerical results show that the FF and NWF perform nearly identical in the scenarios of sparse wavelengths with small conversion range and large wavelengths with small conversion range. The FF outperforms NWF when the wavelength number is large and the conversion range is wide. However, consider the fact that output power strongly deteriorates as a function of the distance between the ingoing and outgoing wavelengths, the NWF policy should be adopted in the practical OBS networks.
