Ring Topology

Ring Topology
How does it work?
Real Life Applications
It is mainly used in engineering and
manufacturing industries.Today, the ring topology
is seldom used.
They are also found in some
office buildings ,school
campuses, etc.
It is usually used in Local Area
Networks or LAN's.
Disadvantages
Each packet of data must pass through all the
computers between source and destination. This
makes it slower than star topology
If one workstation or port goes
down, the entire network gets
affected
Network is highly dependent on the wire or cable
which connects different components. If the cable
or loop encounters a problem, the whole network is
affected
The higher the number of
nodes, the slower the
communication
Moving, adding and changing
devices may affect the network
Slower than a star topology
under normal load.
In order for the nodes to communicate
with each other they must all be switched
on.
Expansion or maintenance
requires the shutdown of the
whole topology.
Advantages
It is a very organised form of networking where
every device has the opportunity to send and
access messages
Even when the load on the network increases,
its performance is better than that of bus
topology
There is no need for network server to
control the connectivity between
workstations.
Additional components do not
affect the performance of
network
Each computer has equal
access to resources.
The ability to generate data packets allows a ring
topology to span far greater distance than bus or
star topologies
Easy to troubleshoot The problem when the ring network shuts
down is that it can be detected easily, and isolated because of pointtopoint
configuration. if you locate where the information is stopping,
it will pinpoint which device or cable from which the trouble is
originating.
A dual ring topology can be
used as a backup if the first ring
fails.
Performs better than a bus
topology under heavy network
load
Does not require a central node to
manage the connectivity between the
computers
Easy to install and configure as removing or adding a
device involves the tampering of only two
connections (as each device is only attached to two
on either side).
Each device has equal access
to data transmissions
The machines on a ring network maintain the
network by negotiating which machine will utilize
the resources of the network before the others
Minimal hardware required
cheap to install and expand
Load of information is spread between devices,
instead of concentrating it onto one single piece
of networking equipment like a star topology.
What is it?
A ring topology is a type of physical topology in
which devices are connected to each other in
the shape of a ring or a loop.
Ring Topology is a network cabling scheme in
which one cable connects all nodes and forms a
closed loop.
