Introduction

Thank you for choosing the 4-Port 10/100M NWay Ethernet Switch

Card. This Introduction chapter will be useful if you are new to Fast

Ethernet, Switch and other new technology featured by the 4-Port

10/100M NWay Ethernet Switch Card. Otherwise, skip ahead to the

Installation chapter.

About Fast Ethernet

Fast Ethernet is a network technology specified by IEEE Standard

802.3u. It extends the traditional 10Mbps Ethernet technology to

achieve 100Mbps transmission and reception, while retaining the

same CSMA/CD Ethernet protocol. Thus while Fast Ethernet

provides a tenfold increase in network capacity, it is wholly

compatible with traditional 10Mbps Ethernet network facilities. This

compatibility is the key to easy and efficient upgrades to 100Mbps in

your network areas needing greater bandwidth. Upgrading selected

areas to Fast Ethernet does not require hardware or software changes

in network areas where traditional 10Mbps Ethernet is providing good

service. For upgrading existing Ethernet installations to 100Mbps,

and especially for selectively upgrading areas needing upgrade, Fast

Ethernet is the clear choice in terms of cost-effectiveness, as well as

convenience and smoothness in transition.

Fast Ethernet comprises two subtypes: 100Base-T4 and 100Base-TX.

100Base-T4 Fast Ethernet can utilize existing Category 3 or Category

4 UTP network cabling, but does not provide for full duplex

operation. 100Base-TX requires Category 5 cabling, but does provide

full duplex operation. Full duplex 100Base-TX operation allows

simultaneous transmission and reception; both at 100Mbps, thus

providing service potentially equal to 200Mbps full-duplex service.

The 4-Port 10/100M NWay Ethernet Switch Card does not support

the 100Base-T4 subtype. To provide compatibility in traditional

10Mbps Ethernet environments, the 4-Port 10/100M NWay Ethernet

Switch Card also supports traditional 10Mbps Ethernet operation, in

full-duplex as well as half-duplex modes. Selection of the best

operation mode in any given installation is automatically governed by

auto-negotiation.

About Auto-negotiation

You have probably had the experience of making a dialup connection

through a modem, and have heard the gravelly−sounding exchanges

between your modem and the modem at the other end of the telephone

line (these exchanges are ordinarily played out through a speaker in

your local modem). As irritating as those few seconds of noise may

be, they do let you know that your modem and the remote modem are

on the job, preparing for your intended communication with the

remote computer.

The preparatory work of the two modems during those few seconds

before you see the “Connect” message is to negotiate the best data

communication scheme which is supported by both modems, and

which is suitable for the quality of the telephone line linkage between

them. The parameters to be settled between the two modems include

best baud rate, compression method, and error correction method.

When the two modems have tested the phone-line quality and settled

on the combination of shared options and parameters which will

provide the best data communication over the connecting phone line,

then you are given the 　”Connect” message which signals the end of

the intermodem negotiation and the beginning of your intended

communication with the remote computer.

Auto-negotiation between devices within an Ethernet LAN is similar

in concept, but much briefer. The two devices involved in the auto-

negotiation will be the 4-Port 10/100M NWay Ethernet Switch Card

serving your station (installed in your computer), and the hub through

which it is connected into the LAN. The options to be negotiated

between the 4-Port 10/100M NWay Ethernet Switch Card and its

supporting hub include Ethernet type (100BASE-TX Fast Ethernet or

10BASE-T Ethernet) and duplex mode (half-duplex, being one-way-

at-a-time, or full duplex, being simultaneous transmit-and-receive).

Startup communication between the two devices occurs when devices

are power-on, the cable connection between them is good, and the

Network Operating System software is running. As soon as those

conditions are satisfied, the preparatory process of auto-negotiation

between the 4-Port 10/100M NWay Ethernet Switch Card and its

supporting hub proceeds automatically. If the hub has auto-

negotiation functionality, then it and the 4-Port 10/100M NWay

Ethernet Switch Card exchange a series of messages in which each

device signals its capabilities and listens for corresponding

information about the other. The auto-negotiation process requires

only a few milliseconds, and the two devices select the best

communication parameters supported by both devices.

If the hub does not have auto-negotiation functionality, then its

monotone (single capability) message will be recognized by the 4-Port

10/100M NWay Ethernet Switch Card’s auto-negotiation facility, and

the 4-Port 10/100M NWay Ethernet Switch Card will simply switch

to the one of its own capabilities which matches that of the hub.

When the preparatory procedure of auto-negotiation is completed,

then the line is ready and will provide a data channel that is optimal

for the two devices. The line will remain ready without further auto-

negotiation action until the linkage is broken. Auto-negotiation then

reoccurs at any time that the linkage is restored, again making the line

ready for optimal data communications.

Switching Technology

Another approach to pushing beyond the limits of 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 of increasing the total network

capacity available to users on a local area network. A switch increases

capacity and decreases network loading by dividing a local area

network into different segments, which don’t compete with each other

for network transmission capacity.

The switch acts as a high-speed selective bridge between the

individual segments. The switch, without interfering with any other

segments, automatically forwards traffic that needs to go from one

segment to another. By doing this the total network capacity is

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 the

existing 10Mbps networks and the new 100Mbps networks.

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 of a router, the setup and maintenance required

make routers relatively impractical. Today switches are an ideal

solution to most kinds of local area network congestion problems.
