Ring topology is a type of network topology where each device is connected to two other devices in a circular fashion, forming a ring. Data can travel in one direction in a unidirectional ring or both directions in a bidirectional ring. Ring topology is used in local and wide area networks like SONET fiber networks. It provides redundancy in case a connection is lost through one node by allowing data to route in the other direction. Some disadvantages are that if one device fails, the entire network is impacted, and it can be more expensive to set up due to hardware requirements.

1. RING TOPOLOGY

2. DEFINITION :
Ring topology is a type of network topology in which each
device is connected to two other devices on either side via an
RJ-45 cable or coaxial cable. This forms a circular ring of
connected devices which gives it its name.
Data is commonly transferred in one direction along the ring,
known as a unidirectional ring. The data is forwarded from
one device to the next, until it reaches the intended
destination. In a bidirectional ring, data can travel in either
direction.

4. Unidirectional
Ring Topology
It involves data traffic
in one direction, either
clockwise or
anticlockwise. This data
network is also called a
half-duplex network.

5. Bidirectional Ring Topology
It involves data traffic in both the directions and is thus called a
full-duplex network.
Bidirectional data transmission is possible by having two
connections between each network node, thus making two ring
networks with data flow in opposite direction to each other.
This type of topology with two rings is sometimes also referred
to as the Dual Network Topology.

8. This topology is used in the local area network and wide area networks. This type of topology is frequently used in
the telecommunication industry and is commonly used in SONET fiber networks. It is used as a backup system in
various companies for their existing network. Once the connection is misplaced through a node, and then it uses
the bidirectional capacity to route traffic in one more way. It is applicable in educational institutions.
The applications of ring topology include the following.
Ring Topology Applications/Uses

10. Coaxial cable (Coax)
A coaxial cable is used in cable TVs and allows a broadband cable Internet
connection using a cable modem.
A coaxial cable can have a transmission speed of 10 Mbps, and a frequency
range of 750 Mhz. Its cable can have maximum distance of up 500m.

13. How does the Ring system work?
How does Ring security work? The
security system sends an alert to your
phone whenever it detects activity.
Arming the system determines which
types of alerts you get. If you have a
Ring Protect Plus plan with professional
monitoring, the monitoring center calls
the police after checking for false
alarms.

14. Data flow
Which method is used in ring
topology to transmit data?
The token ring topology uses an
access method called token passing.

15. Data flow
How does data travel on a ring?
In a ring network, packets of data travel
from one device to the next until they
reach their destination. Most ring
topologies allow packets to travel only in
one direction, called a unidirectional ring
network. Others permit data to move in
either direction, called bidirectional.

17. Advantage
Execution: By executing you can achieve a
ring topology network with less effort.
Devices can be arranged one after the
other without a specific number. There are
no limitations to the number of devices
that you can place. Whenever you add
fresh devices, you only need to move the
adjoining device.
Administration: High-speed data transfer
rates are another classic feature of a ring
network topology. The data transmission
that occurs between each workstation
generally is quite fast here. Even under the
condition of heavy load, interruptions will
not impact its performance.
Adaptability: The construction of ring
topology makes the adaptability of devices
straightforward. Users can keep adding
workstations, and it will still not cause any
performance delays or problems in the
network.
Fidelity: Even though ring topology
requires hardiness, it can still be quite
reliable for use to some extent. Mainly by
using a set of multiple rings. The
bidirectional characteristic of the ring
topology guarantees that there are very
few failures. The data moves in two
directions in a ring topology, and therefore,
for the same node, various paths are used.

18. Advantage
Direction of the Data: The ring
topology’s one-direction data flow
ensures scarce chances of data
collisions. Hence, the data transfer
process is more fluid here.
Server Specifications: Since all
workstations are connected circularly,
there is no need for network servers.
Therefore, each workstation on the ring
topology has its unique connectivity.
The only element necessary here is the
use of special cables to connect each
device on the topology structure.
Troubleshooting Feature: Unless one-
directional, troubleshooting and error
in a ring topology are relatively
straightforward

19. Disadvantage
• 1)●IF ONE DEVICE FAILS,THE ENTIRE
NETWORK IS IMPACTED●
-The major disadvantage of a ring
topology is that if any individual
connection in the ring is broken, the
entire network is affected.
-Ring topology is less reliable as failure
of one device affects whole network.

20. Disadvantage
• 2)EXPENSES-For establishing the
network originally, a ring topology
architecture requires expensive
hardware components. We cannot
link the workstation without the
proper network cards And cables
which makes the installation process
pretty high.

21. Disadvantage
3)All data travel on the network via
every computer over the network
which can reduce performance,so
its speed is slower
4)The failed connection may
disable the whole network unless it
is a dual ring or there is a by-pass
mechanism.
5)Whole network is depended only
in a single cable.--all devices remain
connected to the master when a
cable breaks.
