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 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-T (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 100Mbps
Fast Ethernet is comp atible with 10Mbps Ethernet and 100Mbps Fast
Ethernet environments, it provides a straightforward network upgrade
and takes advantage of the existing investment in hardware, software,
and personnel training.
