Wavelength converters in WDM networks-an improvement in call connection probability

Abstract

Call connection probability in an all optical network (AON) using wavelength division multiplexing (WDM) depends on the number of WDM wavelengths available in a link and on the network capability for wavelength conversion at network nodes. A simpler approach for calculation of call connection probability using wavelength converters has been provided. Expressions for call connection probability, with and without wavelength converters are derived and are combined in a converter availability model, so as to study the impact of wavelength conversion on call connection probability.
