Vitesse Introduces New Gigabit Ethernet Switch ICs

Vitesse Semiconductor introduced two new Gigabit Ethernet switch ICs: Gatwick -- a Layer 3, 24-port tri-speed (10/100/1000) plus 2-port 10 Gbps Switch/Router Integrated Circuit (IC), and Fairoaks -- a low-cost Layer 2+, 24-port tri-speed plus 2-port 10 Gbps Switch IC. Both devices support advanced features such as deep packet and programmable classification for optimizing Quality of Service. They can also differentiate packets and prioritize them based on information inside the packet including Differential Service Code Points (DSCP) and VLAN priorities (IEEE 802.1p). The products also provide jumbo packet support allowing packet sizes greater than 10 Kbytes, as well as double VLAN tag support. Gatwick and Fairoaks have two uplink ports of 10 Gbps and require no external memory or CAMs. Additionally, two of either ICs can be directly connected together to produce a 48-port switch system in a standard 19 inch, 1U high form factor. Vitesse said its two chip count solution for a 48-port Gigabit switch system would reduce the cost of such systems, which currently requires five component chips.
