Abstract :
In this paper, LPF based schedulers for VOQ crossbar switch implementation through FPGA circuits are analysed. Switch performance (average cell latency, queue lengths and loss probability) are evaluated under different traffic conditions. Results of behavioral simulations on implemented circuits are compared with simulations on modeled circuits that are not limited as implemented ones. Particularly consideration is given to required queue lengths and impact of its limitation to scheduler behavior. It is shown that queue length of 127 cells is enough to manage almost any offered load under various traffic conditions that we considered.
