Mesh Topology


Mesh topology connects each node to more than one node. This allows the topology to search for alternative route in case if a host is either down or not responding.

 

Mesh topology is good for long distance networking as it provides back up, rerouting and pass through capabilities. Communication is possible between any two nodes either directly or via other nodes. This is used in large internetworking environment with stars, rings and buses attached to each node. This topology is also suitable for distributed network.

 

There are two types of mesh topology:

  1. Fully connected mesh topology → The mesh topology that has each of the nodes connected to each other nodes in the network with a point-to-point link is known as fully connected mesh topology. This makes it possible for data to be simultaneously transmitted from any node to all other nodes. This topology is too costly and complex thus used mostly to connect only few nodes.
  2. Partially connected mesh topology → The mesh topology that has some of the nodes connected to many other nodes in the network with a point-to-point link is known as partially connected mesh topology. 

Advantage of mesh topology

  • Mesh topology provides fast communication between two nodes.
  • Mesh topology has greater reliability as failure of a node will only impact direct communication and not the complete network.
  • In mesh topology, each node of the network need not have individual routing capability.

Disadvantage of mesh topology

  • Mesh topology is expensive to set up.
  • Mesh topology is difficult to install and configure.
  • Mesh topology requires large cable length.
