Mesh topology is a network topology in which all the network nodes are individually connected to every or most of the other nodes. This particular topology can be further divided into two kinds:

• Fully Connected Mesh Topology
• Partially connected Mesh Topology

In fully connected mesh topology, each node is connected to every other node. It is much like the fully connected graph where all nodes are connected to every other node.

In partially connected mesh topology, not all the nodes are connected to every other node but each node is connected to most other nodes.

The advantages of mesh topology are as follows:

• Each connection can carry its own data load
• It is highly robust
• Any fault can be diagnosed and detected very easily
• It provides security and privacy

The disadvantages are as follows:

• The installation and configuration becomes more and more difficult as the connectivity increases
• Cabling cost is more in case of the fully connected mesh topology as compared to the cabling cost incurred in case of the partially connected mesh topology
• Bulk wiring is required
