This section describes the features of the Switch, as well as giving some background
information about Fast Ethernet, Gigabit Ethernet, and switching technology.
Fast Ethernet Technology
The growing importance of LANs and the increasing complexity of desktop computing
applications are fueling the need for high performance networks. A number of high-speed
LAN technologies are proposed to provide greater bandwidth and improve client/server
response times. Among them, Fast Ethernet, or 100BASE-T, provides a non-disruptive,
smooth evolution from 10BASE-T technology.
100Mbps Fast Ethernet is a standard specified by the IEEE 802.3 LAN committee. It is an
extension of the 10Mbps Ethernet standard with the ability to transmit and receive data at
100Mbps, while maintaining the Carrier Sense Multiple Access with Collision Detection
(CSMA/CD) Ethernet protocol.
Gigabit Ethernet Technology
Gigabit Ethernet is an extension of IEEE 802.3 Ethernet utilizing the same packet
structure, format, and support for CSMA/CD protocol, full duplex, flow control, and
management objects, but with a tenfold increase in theoretical throughput over 100Mbps
Fast Ethernet and a one hundred-fold increase over 10Mbps Ethernet. Since it is
compatible with all 10Mbps and 100Mbps Ethernet environments, Gigabit Ethernet
provides a straightforward upgrade without wasting a company’s existing investment in
hardware, software, and trained personnel.
The increased speed and extra bandwidth offered by Gigabit Ethernet is essential to coping
with the network bottlenecks that frequently develop as computers and their busses get
faster and more users use applications that generate more traffic. Upgrading key
components, such as your backbone and servers to Gigabit Ethernet can greatly improve
network response times as well as significantly speed up the traffic between your
subnetworks.
Gigabit Ethernet enables fast optical fiber connections to support video conferencing,
complex imaging, and similar data-intensive applications. Likewise, since data transfers
occur 10 times faster than Fast Ethernet, servers outfitted with Gigabit Ethernet NICs are
able to perform 10 times the number of operations in the same amount of time.
In addition, the phenomenal bandwidth delivered by Gigabit Ethernet is the most cost-
effective method to take advantage of today and tomorrow’s rapidly improving switching
and routing internetworking technologies.
