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
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.
