INTRODUCTION
This chapter describes the features of the DES-1016D 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.
