D-Link DGS-1005D [4/18] Gigabit ethernet technology

NTRODUCTION

This section describes the features of the DGS-1005D, 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 bus speeds 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.
