Dual-Speed Ethernet Technology

The growing importance of LANs and the increasing complexity of
desktop computing applications are fueling the need for higher
performance networks. A number of high-speed network
technologies have been proposed to provide greater bandwidth and
improve client/server response times. Among them, Fast Ethernet,
or 100Base-T, provides a non-disruptive and smooth evolution from
the current 10Base-T Ethernet technology.
Fast Ethernet is a new standard specified by the IEEE 802.3 LAN
committee. It is an extension of the 10 Mbps Ethernet standard
with the ability to transmit and receive data at 100 Mbps, while
maintaining the CSMA/CD Ethernet protocol. Since 100 Mbps
Fast Ethernet is compatible with 10 Mbps Ethernet environments,
it provides a straightforward upgrade and takes advantage of the
company’s existing investment in hardware, software, and
personnel training.
One of the biggest advantages of Fast Ethernet over other high
speed networking solutions is the ability of existing 10 Mbps
Ethernet networks to be gradually upgraded; network performance
can be improved by adding Fast Ethernet components only when
and where needed. This cost-efficient migration strategy is realized
through dual-speed devices which can operate at either 10 Mbps or
100 Mbps, depending on the speed of the device it is connected to.
Fast, efficient and relatively inexpensive dual-speed devices are
made possible because there is no need to translate between
Ethernet and Fast Ethernet protocols. This allows for much lower
latencies (making your network faster), and easy installation,
especially if the devices use NWay Auto-Negotiation technology.
NWay is implemented on a port-by-port basis on dual-speed
devices. If NWay is implemented on a port it will automatically
sense the connection speed (10 or 100 Mbps) and duplex mode (full
or half) of any device connected to that port. NWay will establish
the connection at the highest speed attainable by both devices and
will use full duplex transmission if both devices have this
capability.
