1 INTRODUCTION

This section describes the features of the TE100-S44/ TE100-S88,
as well as giving some background information about Ethernet/
Fast Ethernet switching technology.

Fast Ethernet Technology

The rapid growth of LANs and 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, Fast Ethernet, or 100Base-T, provides a non­disruptive, smooth evolution from the current 10Base-T
technology. This non-disruptive and smooth evolution 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 company’s existing investment in
hardware, software, and personnel training.

Switching Technology

Another approach to push beyond the limits of the Ethernet
technology is the development of switching technology. A switch
bridges Ethernet packets at the MAC address level of the Ethernet
protocol transmitting among connected Ethernet or Fast Ethernet
LAN segments.

Switching is a cost-effective way to increase the total network
capacity available to users on a local area network. A switch
increases network capacity and decreases network loading by
making it possible for a local area network to be divided into
different segments which don’t compete with each other for
network transmission capacity, giving a decreased load on each.

The switch acts as a high-speed selective bridge between the
individual segments. Traffic that needs to go from one segment to
another is automatically forwarded by the switch, without
interfering with any other segments. This allows the total network
capacity to be multiplied, while still maintaining the same network
cabling and adapter cards.

For Fast Ethernet networks, a switch is an effective way of
eliminating problems of chaining hubs beyond the “two-repeater
limit.” A switch can be used to split parts of the network into
different collision domains, making it possible to expand your Fast
Ethernet network beyond the 205 meter network diameter limit
for 100BASE-TX networks. Switches supporting both traditional
10Mbps Ethernet and 100Mbps Fast Ethernet are also ideal for
bridging between existing 10Mbps networks and new 100Mbps
networks.

10/100 Fast Ethernet Switch User’s Guide

Introduction 3

Switching LAN technology is a marked improvement over the
previous generation of network bridges, which were characterized
by higher latencies. Routers have also been used to segment local
area networks, but the cost and the setup and maintenance
requirements make routers relatively impractical. Today’s
switches are an ideal solution to most local area network
congestion problems.

Features

The Switches were designed for easy installation and high
performance in an environment where traffic on the network and
the number of users increase continuously.

The Switches with their small, compact size were specifically
designed for small to large workgroups (the 4-port switch for
smaller workgroups and the 8-port for larger workgroups). These
Switches can be installed where space is limited; moreover, they
provide immediate access to a rapidly growing network through a
wide range of user-reliable functions.

The Switches are ideal for deployment with multiple high-speed
servers for shared bandwidth 10 Mbps or 100 Mbps workgroups.
In 200 Mbps full-duplex mode, any port can provide workstations
with a congestion-free data pipe for simultaneous access to the
server.

The Switches are expandable by cascading two or more switches
together. As all ports support 200 Mbps full duplex, the Switches
can be cascaded from any port and to any number of switches.

The Switches are a perfect choice for site planning to upgrade to
Fast Ethernet in the future. Ethernet workgroups can connect to
the Switches now, and change adapters and hubs anytime later

10/100 Fast Ethernet Switch User’s Guide

4 Introduction

without the need to change the Switches or reconfigure the
network.

The Switch combines dynamic memory allocation with store-and­forward switching to ensure that the buffer is effectively allocated
for each port while controlling the data flow between the transmit
and receive nodes to guarantee against all possible packet loss.

The Switch is unmanaged 10/100 Fast Ethernet Switch that offers
solutions in accelerating small Ethernet workgroups’ bandwidths.
Other key features are:

Ports 4 or 8 UTP/STP ports (depending on the model), all with
auto-negotiation and operating at 10/100 Mbps for connections to
servers and hubs. All ports can be configured for full or Half­duplex operation.

♦ Uplink/ MDI-II (media dependent interface) port for uplink

to another switch, hub or repeater. Please note that if you
are using the uplink port, you will be unable to use port one
as these two ports are logically connected.

Performance features

♦ Store and forward switching scheme capability to support

rate adaptation and ensures data integrity.

♦ N-way Auto-negotiation for any port. This allows for auto-

sensing of speed (10/100 Mbps)and auto-detecting mode
(Full-duplex or Half-duplex) thereby providing you with
automatic and flexible solutions in your network
connections.

♦ Auto polarity detection for correcting incorrect polarity on

the receiving twisted pair cable at each port.

♦ Data forwarding rate 148,800 pps per port at 100% wire

speed.

10/100 Fast Ethernet Switch User’s Guide

Introduction 5

♦ Data filtering rate at 148,800 pps per port, eliminates all

error packets at 100% wire speed.

♦ 8K active MAC address entry table per device with self

learning and table aging.

♦ 8 MB packet buffer per device.
