This section describes the features of the DES-1009G Gigabit
Ethernet Switch, as well as giving some background information
about Gigabit Ethernet, Fast 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 supplementing the 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 will greatly improve network response times as well as
significantly speed up the traffic between your subnets.
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 NIC's
are able to perform 10 times the number of operations in the same
amount of time.
