Network Link and Activity Indication


Functional Description

The Broadcom Ethernet controller connects the computer to an Ethernet network. The controller incorporates a technology that transfers data at a maximum rate of 100 Mbit/s for Fast Ethernet controllers, or one gigabit per second (10 times the rate of Fast Ethernet controllers) for Gigabit Ethernet controllers.

The Gigabit Ethernet controller targets the increased congestion experienced at the backbone and server in today's networks and provides a future upgrade path for high-end workstations that require more bandwidth than the Fast Ethernet controller can provide.
