From "The GIGAswitch System: A High-Performance Packet Switching Platform". Robert J. Souza et al (7 listed authors) Digital Technical Journal, vol. 6, no. 1 1994. The switch fabric is a non-blocking crossbar capable of full 100 Mbps full duplex rates (actually, about 150 Mbps: a 25 Mhz clock with a 6 bit data path). Custom VLSI. The FDDI cards have 1 MB/port that (i believe) is used for packet buffering. Both input and output buffering is required. Cut through forwarding is supported. Bottom line: about 270,000 pps per port, 14 microsec. forwarding latency AND superior reliability.
