1 INTRODUCTION
This section describes the features of the DES-3208, as well as
giving some background information about Ethernet/ Fast
Ethernet switching technology.
Fast Ethernet Technology
The growing importance of LAN s 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 the
current 10Base-T technology. The non-disruptive and smooth
evolution nature, and the dominating potential market base,
virtually guarantee cost effective and high performance Fast
Ethernet solutions in the years to come.
100Mbps Fast Ethernet is a new 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 CSMA/CD Ethernet protocol. Since the
100Mbps Fast Ethernet is compatible with all other 10Mbps
Ethernet environments, it provides a straightforward upgrade and
takes advantage of the company’s existing investment in
hardware, software, and personnel training.
