INTRODUCTION
This section describes the features of the 5-Port 1000BASE-T
Gigabit Ethernet Switch, as well as providing some
background information about Gigabit Ethernet and switching
technology.
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 100-Mbps Fast Ethernet and a hundredfold
increase over 10-Mbps Ethernet. Since it is compatible with all
10-Mbps and 100-Mbps 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 subnets.
Gigabit Ethernet supports video conferencing, complex
imaging, and similar data-intensive applications. Likewise,
since data transfers occur 10 times faster than Fast Ethernet,
4
servers outfitted with Gigabit Ethernet NIC’s are able to
perform 10 times the number of operations in the same amount
of time.
Switching Technology
Another key development pushing the limits of Ethernet
technology is in the field of switching technology. A switch
bridges Ethernet packets at the MAC address level of the
Ethernet protocol transmitting among connected Ethernet or
fast Ethernet LAN segments.
Switching is a cost-effective way of increasing the total
network capacity available to users on a local area network. A
switch increases capacity and decreases network loading by
making it possible for a local area network to be divided into
different segments which don’t compete with each other for
network transmission capacity, giving a decreased load on
each.
The switch acts as a high-speed selective bridge between the
individual segments. Traffic that needs to go from one segment
to another is automatically forwarded by the switch, without
interfering with any other segments. This allows the total
network capacity to be multiplied, while still maintaining the
same network cabling and adapter cards.
Switching LAN technology is a marked improvement over the
previous generation of network bridges, which were
characterized by higher latencies. Routers have also been used
to segment local area networks, but the cost of a router and the
setup and maintenance required make routers relatively
