transitioning interfaces into a low-power state without interrupting the
network connection.
•Power Saving Technology:
Power saving by link status. If there is no link on a port, such as when
there is no computer connected to the port or the connected computer is
powered off, D-Link's Green Technology will enter a "sleep mode",
drastically reducing power used for that port.

Switching Technology

Switching is a cost-effective way of increasing the total network capacity
available to users on a LAN. If an Ethernet network begins to display
symptoms of congestion, low throughput, slow response times, and high
rates of collision, installing a switch to a network can preserve much or all
of the existing network's cabling and workstation interface card
infrastructure, while still greatly enhancing the throughput for users. A
switch is a viable solution even if demanding applications, such as
multimedia production and video conferencing, are on the horizon. The
most promising techniques, as well as the best return on investment, could
well consist of installing the right mixture of Ethernet switches.
A switch increases capacity and decreases network loading by dividing a
local area network into different LAN segments. Dividing a LAN into
multiple segments is one of the most common ways of increasing available
bandwidth. If segmented correctly, most network traffic will remain within
a single segment, enjoying the full-line speed bandwidth of that segment.
Switches provide full-line speed and dedicated bandwidth for all
connections. This is in contrast to hubs, which use the traditional shared
networking topology, where the connected nodes contend for the same
network bandwidth. When two switching nodes are communicating, they
are connected with a dedicated channel between them, so there is no
contention for network bandwidth with other nodes. As a result, the switch
considerably reduces the likelihood of traffic congestion.
For Ethernet networks, a switch is an effective way of eliminating the
