Performance Analysis of a Photonic Single-Hop ATM Switch Architecture with Bursty and Correlated Arrivals

We consider a photonic ATM switch based on the single-hop WDM architecture. The switch operates under schedules that mask the transceiver tuning latency. We develop an exact queueing-based decomposition algorithm to obtain the queue-length distribution at the input and output ports of the switch. The analysis is carried out using arrival models that capture the notion of burstiness and correlation, two important characteristics of ATM type of traffic, and which permit non-uniform destinations. We then derive analytic expressions for the cell-loss probability at the input and output ports, and the delay distribution to traverse the switch. To the best of our knowledge, such a comprehensive performance analysis of an optical switch architecture has not been done berfore.
