Abstract
A performance analysis is presented for a slotted optical packet switch using wavelength conversion to resolve packets contention at the switch output ports. The wavelength converters are shared per output link where each output link consists of multiple fibers. The destinations, in terms of the output ports of the switch, of the incoming packets to the switch obey Zipf law to reflect a more realistic behavior of the Internet data traffic [4]. Consequently, the switch input load is also assumed to follow Zipf law. A symmetric switching architecture is evaluated by means of analytical model and the results are confirmed by simulations under different switch configurations. The evaluation metrics are packet loss probability and wavelength conversion bank utilization under different degrees of biasness, number of converters, and offered load points.
