Abstract

In this paper, we discuss the design and modeling of the OPSnet asynchronous optical packet switch. We focus on traffic modeling and the integration of Diff- Serv per-hop-behaviour in the optical packet switch architecture. We demonstrate the influence of traffic shaping, traffic aggregation and DiffServ prioritisation on the performance of the switch using simulation results, and present an analytical model to quantify the drop probability for the various DiffServ classes as a function of the class mix and the buffer depth
