Performance model of an optical switch using fiber delay lines for resolving contentions

The performance of an optical switch that handles contention resolution using a fiber delay line (FDL) is modeled and evaluated. We propose using a simple optical buffer that contains only a single FDL for contention resolution. The analytical model derived for the performance of an optical switch based on this buffer is verified using simulations. The analytical model can be utilized with both packet and burst switching schemes to characterize the performance of switches augmented with this FDL architecture.
