Performance evaluation of an optical packet "scheduling" switch

In this paper a performance analysis of the packet scheduling switch is presented. The scheduling switch uses a series of feedforward delays interconnected with elementary optical switches. This series of programmable delay blocks constitutes an optical buffer of depth T, whose purpose is to delay/re-arrange incoming packets that request the same outgoing link so as to resolve or reduce packet contention. Performance results have been obtained for random Bernoulli traffic, Pareto traffic, as well as for smooth traffic with an upper bound of inherent burstiness.
