What is Mesh Topology?
In a mesh network
topology, each of the network node, computer and other devices, are
interconnected with one another. Every node not only sends its own signals but
also relays data from other nodes. In fact a true mesh topology is the one
where every node is connected to every other node in the network. This type of
topology is very expensive as there are many redundant connections, thus it is
not mostly used in computer networks. It is commonly used in wireless networks.
Flooding or routing technique is used in mesh topology.
Types of Mesh Network
topologies:-
1)Full Mesh Topology:-

In this, like a true
mesh, each component is connected to every other component. Even after
considering the redundancy factor and cost of this network, its main advantage
is that the network traffic can be redirected to other nodes if one of the
nodes goes down. Full mesh topology is used only for backbone networks.
2) Partial Mesh
Topology:-
This is far more
practical as compared to full mesh topology. Here, some of the systems are
connected in similar fashion as in mesh topology while rests of the systems are
only connected to 1 or 2 devices. It can be said that in partial mesh, the
workstations are ‘indirectly’ connected to other devices. This one is less
costly and also reduces redundancy.
Advantages of Mesh
topology
1) Data can be
transmitted from different devices simultaneously. This topology can withstand
high traffic.
2) Even if one of the
components fails there is always an alternative present. So data transfer
doesn’t get affected.
3) Expansion and
modification in topology can be done without disrupting other nodes.
Disadvantages of Mesh
topology
1) There are high
chances of redundancy in many of the network connections.
2) Overall cost of this
network is way too high as compared to other network topologies.
3) Set-up and
maintenance of this topology is very difficult. Even administration of the
network is tough.
