Definition

Quad FastEthernet (QFE)

Quad FastEthernet (QFE) is a network interface card (NIC) manufactured by Sun Microsystems that is designed to enhance the bandwidth of a Peripheral Component Interconnect (PCI)-based server using Sun Microsystem's Solaris 8 or later operating environment. Speeds of up to 100 megabits per second (Mbps) are provided by converting PCI data streams into Fast Ethernet traffic. QFE cards are hot-swappable, minimizing downtime, and comply with the IEEE 802/3U Ethernet standard. A single card can work with up to four network interfaces at a time and provide support for multihoming.
