INTRODUCTION

This section describes the features of the 8-Port
10/100/1000Mbps Gigabit Ethernet Switch, as well as giving
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, 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.
