- Abstract
We compute analytically burst blocking probabilities in an OBS switch when limited-range wavelength conversion is employed. Two separate queueing models are proposed and analyzed approximately; one for the case where the degree of conversion d is 1 or 2, another for large values of d. The arrival process of bursts is assumed to be an IDLE-ON process. The accuracy of these queueing models was tested against simulation. We show numerically that in order to keep the burst blocking probability within an acceptable level, the utilization of each wavelength has to be low.
