Switching Technology
This section provides a brief overview of switching technology, including Fast
Ethernet and Gigabit Ethernet.
An Ethernet switch is a device that can direct network traffic among several
Ethernet and Fast Ethernet networks. A switch increases network capacity and
decreases network loading by making it possible for a LAN to be divided into
multiple, unique dedicated
segments.
In Fast Ethernet networks, a switch allows chaining of hubs beyond the “two-
repeater limit.” A switch can be used to separate the network into different
collision domains, which allows expansion beyond the 205 meter diameter limit
for 100Base-TX networks.
Switch Acts as a Bridge Between Network Segments
A switch acts as a high-speed selective bridge between individual segments.
Traffic that needs to go from one segment to another is automatically forwarded
by a switch, without interfering with any other segments. This allows the total
network capacity to be multiplied while decreasing network loading.
