Large optical packet/burst switch with internal fiber interconnections

Abstract

We present architecture of a large optical packet/burst switch comprising a number of smaller switching fabrics that are interconnected by internal fiber links. The switching fabrics are based on the broadcast-and-select architecture, while the internal interconnection network is a full mesh. An extensive study on physical and switch performance has been performed and results concerning scalability, packet/burst loss rate and throughput for four scheduling algorithms are shown.
