Abstract

In this paper, a real output queuing switch prototype implementation is presented. This implementation is based on a novel high speed multidrop backplane and a general purpose line card which includes a Virtex-II 6000 FPGA. This switch is named GMDS (Gigabit MultiDrop Switch) and its main features are the switch matrix replacement by the multidrop backplane -increasing system reliability-, variable lenght packet switching support -avoiding bandwidth efficient loss-, multiple output queuing structure for supporting QoS (Quality of Service) and a minimum speedup.
