Abstract :
Call connection probability in an all-optical network using wavelength division multiplexing (WDM) depends on the number of WDM wavelengths and on the network capability for wavelength conversion at network nodes. New closed-form expressions for call connection probability are derived which reflect these dependencies. These expressions are combined in a converter availability model to study the impact of wavelength conversion on call connection probability and the tradeoff between network wavelength conversion capability and the number of WDM wavelengths
