Abstract
Methods and systems for determining optical network utilization efficiency include generating a random demand set and calculating a demand fill ratio (DFR) based on the random demand set. The random demand set includes network demands for a given optical network topology that provide 100% of the wavelength slots in the optical network topology. The DFR may be calculated using different wavelength assignment algorithms, such as a first fit wavelength assignment algorithm, from the randomly generated demands in the random demand set. The DFR may be calculated without and with wavelength conversion nodes.
