INTRODUCTION

This chapter describes the features of the DES-1024D and some background
information about Ethernet/Fast Ethernet switching technology.

Fast Ethernet Technology

Ethernet, along with its speedier counterpart Fast Ethernet, is the
most popular networking standard in use today. 100BaseT Fast
Ethernet is an extension of the 10BaseT Ethernet standard,
designed to raise the data transmission capacity of 10BaseT from
10Mbits/sec to 100Mbits/sec. An important strategy incorporated by
100BaseT is its use of the Carrier Sense Multiple Access with
Collision Detection (CSMA/CD) protocol - which is the same
protocol that 10BaseT uses - because of its ability to work with
several different types of cable, including basic twisted-pair wiring.
Both of these features play an important role in network
considerations, and they make 100BaseT an attractive migration
path for those networks based on 10BaseT. Since the 100Mbps Fast
Ethernet is compatible with all other 10Mbps Ethernet
environments, it provides a straightforward upgrade and takes
advantage of the existing investment in hardware, software, and
personnel training.

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 an 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, dedicated to bandwidth for all connections.
This is in contrast to the 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 reduces
considerably the likelihood of traffic congestion.

For Fast Ethernet networks, a switch is an effective way of eliminating the
problem of chaining hubs beyond the “two-repeater limit.” A switch can be
used to split parts of the network into different collision domains, 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 the existing 10Mbps networks and the new 100Mbps
networks.

Switching LAN technology is a marked improvement over the previous
generation of network hubs and bridges, which were characterized by higher
