FBSF: a new fast packet switching fabric based-on multistage interconnection network with multiple outlets
ByoungSeob Park, SungChun Kim · 2002
In this paper, we propose a new ATM switch architecture with output queueing. The proposed switch, FBSF (FAB Banyan Switching Fabrics) can deliver up to 2r packets simultaneously destined for the same outlet in a single time slot. The switch fabrics consists of Batcher sorter, a radix-r double shuffle network, r-packet distributors, two FAB networks, and output buffer modules. The performance of the switch fabric is evaluated by measures of throughput, average queue length, and average waiting time. Numerical results indicate that the switch exhibits very good delay-throughput performance over a wide range of input traffic.
