This section describes the f eatures of the Switch, as well as givin g some backgroun d informatio n
about Fast Ethernet, Gigabit Ethernet, and switching technology.
NTRODUCTION
Fast Ethernet Technology
The growing importance of LANs and the increasing complexity of desktop computing
applications are fueling the need for high performance networks. A number of high-speed LAN
technologies are proposed to provide greater bandwidth and improve client/server response
times. Among them, Fast Ethernet, or 100BASE-T, provides a non-disruptive, smooth evolution
from 10BASE-T technology.
100Mbps Fast Ethernet is a standard specified by the IEEE 802.3 LAN committee. It is an
extension of the 10Mbps Ethernet standard with the ability to transmit and receive data at
100Mbps, while maintaining the Carrier Sense Multiple Access with Collision Detection
(CSMA/CD) Ethernet protocol.
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 100Mbps Fast Ethernet and a one
hundred-fold increase over 10Mbps Ethernet. Since it is compatible with all 10Mbps and
100Mbps Ethernet environme nts, Gigabit Ethernet provides a straightfo rward upgrade withou t
wasting a company’s exist ing investment in hardware, software, and trained personnel.
The increased speed and extra band width offe red by Gigabit Ethe rnet is essential to co ping 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 subnetworks.
Gigabit Ethernet enables fast optical fiber connections to support video conferencing, complex
imaging, and similar data-intensive applications. Likewise, since data transfers occur 10 time s
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.
In addition, the phenomenal bandwidth delivered by Gigabit Ethernet is the most cost-effective
method to take advantage of today and tomorrow’s rapidly improving switching and routing
internetworking technologies.

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 (from one port to another) is
automatically forwarded by the switch, without interfering with any other segments
(ports). This allows the total network capacity to be multiplied, while still maintaining
the same network cabling and adapter cards.
For Fast Ethernet or Gigabit Ethernet networks, a switch is an effective way of
eliminating problems of chaining hubs beyond the “two-repeater limit.” A switch can be
used to split parts of the network into different collision domains, for example, making
it possible to expand your Fast Ethernet network beyond the 205 meter network
diameter limit for 100BASE-TX networks. Switches supporting both traditional 10Mbps
Ethernet and 100Mbps Fast Ethernet are also ideal for bridging between existing
10Mbps networks and new 100Mbps networks.
Switching LAN technology is a marked improvement over the previous generation of
network bridges, which were characterized by higher latencies. Routers have also been
used to segment local area networks, but the cost of a router and the setup and
maintenance required make routers relatively impractical. Today’s switches are an
ideal solution to most kinds of local area network congestion problems.
DES-1210G 10/100/1000 Mbps Stand-alone Switch
General Description of Switch
The DES-1210G Switch module is equipped with eight ports providing dedicated 10 or
100 Mbps bandwidth. These ports can be used for connecting PCs, servers, and hubs.
The eight dual speed ports use standard twisted pair cabling and are ideal for
segmenting networks into small, connected subnets. Each port can support up to 200
Mbps of throughput in full-duplex mode. In addition, the Switch is equipped with two
Gigabit fiber optic uplink ports enabling convenient access to a server or network
backbone for all the clients served by the Switch. This stand-alone Switch enables the
network to use some of the most demanding multimedia and imaging applications
concurrently with other user applications without creating bottlenecks. The built-in
console interface can be used to configure the Switch’s settings for Priority Queuing,
VLAN, and Port Trunk Groups, Port Monitoring and Port Speed.
