26-port 10/100/1000Mbps Gigabit & Fast Ethernet Switch

Introduction

This chapter describes the features of the Switch and some back- ground information about Ethernet/Fast Ethernet/Gigabit 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 perfor- mance 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.

100Mbps Fast Ethernet is a 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 envi- ronments, it provides a straightforward upgrade and takes advantage of the existing investment in hardware, software, and personnel train- ing.
