Chapter 1. Introduction
Benefits of Switching
Ethernet switching technology has dramatically boosted
the total bandwidth of a network. It puts configuration
flexibility and bandwidth adaptability into the local
workgroups where the majority of work is generated.
It further eliminates congestion problems inherent to the
CSMA/CD protocol and improves predictable response
time under heavy network loads. Expensive routing
equipment was used in the pas t to reduce the congestion
under heavy loads.
The new wave of object-oriented client and server
applications demands higher bandwidth and tighter
integration of client work stations with servers. The old
shared-access Ethernet technology provides neither
enough bandwidth nor predictable response time for this
new wave of workgroup computing.
Fast Ethernet switching not only satisfies both technical
and business requirements, but also p reserves the user’s
existing investment in the huge 10BASE-T Ethernet
installed base.
This compatibility ensures a path for users to add, c hange ,
and migrate to Fast Ethernet as demands emerge. It also
provides a low cost and flexible bandwidth so lution dire ctly
to local workgroups where the majority of work is
generated, reducing the need for expensive network
equipment.

Eight Ports Fiber-Optic Ethernet Switch
The FNSW-8088F has eight multi-mode fiber ports. And
for FNSW-8086F, it has 6-port 100BASE-FX ports and 2port 10/100BASE-TX ports.
This switch makes it possible to join a 100Mbps Fast
Ethernet network to an existing 1 0Mbps Ethernet network
(FNSW-8086F). Its internal cache buffers the traffic from
the higher bandwidth 100Mbps segment to the 10Mbps
segment. If you later decide to make both segments
100Mbps Fast Ethernet, the ports of the switch will
automatically sense the change and adjust to 100Mbps
operation.
In addition to the benefits of integrating 10Mbps and
100Mbps networks through TP ports, this switch is also
useful for segmenting networks that is bogged down with
excess traffic as a fiber-optic switching backbone. By
splitting a network into several segments and bridging
them, you can cut the traffic load on your network and
reduce collisions on each segment, especially if you can
minimize intersegment traffic by placing users and devices
that normally talk to each other on the same segment.
This switch fully complies with IEEE802.3u, 100BASE-TX,
100BASE-FX, and IEEE802.3, 10BASE-T standards. It
features "wire-speed” switching mechanisms as well as
the ability to filter local traffic, collisions, and error pack ets
to maximize network performance.
This eight-port switch also facilitates an affordable and
efficient migration path to 100Mbps Fast Ethernet and can
continue to enhance your network's performance even if
6

you upgrade your existing network with standar d Ethernet
applications, internetworking systems and client-side
adapters to minimize migration costs.

Appendix B – Introduction to LAN &
Ethernet Technologies
In the last ten years, as communication and business
applications become increasingly complex, computer
network has evolved as a very important part of the
enterprise infrastructure. Communication systems like
Local Area Network (LANs) have grown into a
sophisticated, powerful, yet flexible technology today.
Among different types of Local Area Networks, such as
FDDI, ATM, Token Ring and Apple Talk, Et hernet strikes a
good balance between speed, price, ease of installation,
and supportability.
This primer helps to explain this most popular technology
and its associated products such as Ethernet hubs and
switches.
LAN
In order to reduce the expense on compu t er hardware and
software and to easily share information, LAN technologies
were developed for people to share distribu ted computing
resources. LAN connects independent computers, file
servers, printers, etc. together within a confined geographic
area, usually a single building or a college campus. As
LAN expands to link hundreds and thousands of
computers, various network protocols and media have
developed to meet the organization’s different
requirements. At times, multiple LANs that are
FNSW-8086 / 8088F User's Manual
19
geographically dispersed may need to
become so called Wide Area Network (WAN).
connect together and
Ethernet Technologies
More than 80 percent of all Local Area networks are
installed with Ethernet. The Institute of Electrical and
Electronic Engineers (IEEE) define the standard of
Ethernet as IEEE 802.3. The IEEE 802.3 provides rules
for configuring Ethernet LANs, specifies how elements
should interact with one another, and different types of
media that can be used, as well as data rate (10Mbps) of
Ethernet. Ethernet supports just about all kinds of popular
network protocols. It is one of the most ideal networking
technologies today.
Fast Ethernet
For networks that need higher transmission speeds, IEEE
has also established the standard 802 .3u, which raises the
Ethernet speed limit from 10 Mbps to 100 Mbps. This
allows a network device to transmit data through media
such as category 5 UTP (Unshielded Twisted Pair) cable
or fiber optic cable at the rate of 100 Mbps instead of 10
Mbps. A number of other high-speed LAN technologies
are also available for high bandwidth and good client
server response time. However, Fast Ethernet offers the
best solution that provides smooth migration from 10Ba seT technology to 100 Base-TX. It requires only minimal
changes with existing cabling infrastructur e. Fast Ether net
and its successors have been said to be the most cost
20
NOVASwitch Series
effective and high-performance networking solutions of th e
future.
The Fast Ethernet contains three different cabling
schemes. 100Base-TX for use with category 5 UPT/STP
cable, 100Base-FX for use with Multi-mode fiber-optic
cable, and 100Base-T4 for use with cable 3,4,or 5 UPT
cable. Among three of them, 100Base-TX is most
compatible to 10Base-T. It allows users to retain the
existing 10Base-T cabli ng infrastructure, thus becomes the
most popular Fast Ethernet technolog y. Gigabit Ethernet
is still in the process of development. Other than supports
higher data transfer speed, this techn ology also promises
for an easy migration path.
Ethernet Products
Hub
Hub is a central connection point for wiring the network. It
connects two or more Ethernet segments of any media
type. When transmitting signal begins to deteriorate, which
is caused by the limitation of media length, hub simply
takes the incoming signal and repeats or amplifies it out to
all ports connected. Hub, also called repeater, on ly allows
users to share Ethernet. Individuals of a shared network
can only get a percentage of the available network
bandwidth, therefore, a network of repeaters also named
Shared Ethernet”.

Switches
The function of a switch is to connect separate ne tworks
together. A Switch maps the Ethernet addresses of the
nodes residing on each network segment and then allows
only the necessary traffic to pass through. When a pac ket
is received by the switch, the switch determines the
destination and source segments of a packet and forward
it to the right direction or drop it if the destination and the
source are originated from the same network. Switches
also prevent bad or misaligned packets from spreading
into the rest of network, thus increasing efficiency of the
network transmission.
There are two basic architectures of LAN switches, cutthrough and store-and-forward. Cu t-through switches only
examine the destination address before forwarding it on to
its destination segment. A store-and-forward switch
accepts and analyzes the entire packet before forwarding it
to its destination. It allows the switch to catch certain
packet errors and keep them from propagating through the
network. Today there are a large number of hybrid
switches available that mix both cut through and store-andforward architectures.
