This paper evaluates speedup and expansion in a multi-stage Terabit switch fabric. Single-stage switch fabrics, e.g. crossbar switches, are difficult to scale up to a Terabit system. Hence, a multi-stage switch fabric, where traffic can be distributed on different chips, offers a promising perspective. We evaluate buffer usage, number of out-of-sequence cells and fabric delay. Simulation results obtained in OPNET Modeler show that speedup outperforms expansion and that both approaches significantly gain from applying an output line speedup. By reducing the buffer usage in the middle stage, fewer cells arrive out-of-sequence and hence the need for re-sequencing is decreased as well.
