Introduction
This chapter describes the features of the Switch and some
background information about Ethernet/Fast Ethernet
switching technology.
Fast Ethernet Technology
The growing importance of local area networks (LANs) and
the increasing complexity of desktop computing
applications are fueling the need for high performance
networks. A number of high-speed LAN technologies have
been proposed to provide greater bandwidth and improve
client/server response times. Among them, 100BASE-TX
(Fast Ethernet) 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 Switch is compatible with all 10Mbps
Ethernet environments, it provides a straightforward
upgrade and takes advantage of the existing investment in
hardware, software, and personnel training.
Switching Technology
Another approach to pushing beyond the limits of Ethernet
technology is the development of switching technology. A
