Abstract

We consider a broadcast-and-select (single hop) photonic ATM switch architecture which operates under schedules that mask the transceiver tuning latency. Within this work, we develop a set of expressions to obtain the probability distribution of a pair of cells which arrive to an WDM switch consecutively being separated upon retransmission out of the switch by a period of t slots. This measure warrants investigation in that it is a necessary first step to characterizing the impact of a WDM architecture on the delay jitter of a data flow. The analysis is carried out using arrival models that capture the notions of burstiness and correlation, two important characteristics of ATM traffic. The results show that the impact of the switch architecture on the delay variation of two cells' transversing the switch may be significant and unintuitive, but can be predicted based on scheduling parameters and other traffic patterns.
