cisco extreme networks gigabit switches uk, 1000Base-SX and 1000Base-T Gigabit switches from 3Com, Cisco, Extreme Networks, Allied Telesyn, D-Link and Netgear.

Switches

A Network Switch in it's simplest form is multi port bridge, a device which is able to determine the source and destination address of packets, and forwards packets appropriately. This technology replaced hubs which forward data to every port this congesting the network with unwanted packets.

Switches today vary from the above to very sophisticated devices, at their best offering routing and high level traffic management in hardware ASIC's offering wire speed performance up to 10GB.
