Type of Network Topology

What is Mesh Topology? Advantages & Disadvantages

In Mesh Topology, all the computers are inter-connected to each other in a network. Each computer not only sends its own signals but also relays data from other computers. This type of topology is very expensive as Its very difficult to establish the connections of the mesh topology. In a Mesh topology every node has a point-to-point connection to the other node. The connections in the mesh topology can be wired or wireless.

Mesh Topology can be divided into two types:

  1. Fully connected mesh topology
  2. Partially connected mesh topology

1) Fully Connected Mesh Topology:

A fully connected mesh topology has all the computers connected to every other computer. Full Mesh is a network in which devices are organized in a mesh topology. A full mesh topology provides a great deal of redundancy, but because it can be prohibitively expensive to implement, it is usually reserved for network backbones. Even after considering the cost and the redundancy factor 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 network is used only for backbone networks.

2) Partial Connected Mesh Topology:

Partial Mesh topology is more practical as compared to full mesh topology. In partially connected mesh topology, all the nodes are not necessary to be connected with each other in a network. This partial mesh topology is less costly compared to full mesh topology and also it reduces the redundancy.


To find the no: of physical links in a fully connected mesh topology with n nodes, we first consider that each node must be connected to every other node.

n(n – 1)  for half duplex communication

n(n -1) /2  for full duplex communication.

Characteristics of Mesh Topology:

  • Fully connected
  • Robust
  • Not flexible
  • Poor expandability

Advantages of Mesh Topology:

  1. there is no traffic problem as there are dedicated point to point links for each computer.
  2. It has multiple links, so if one route is blocked then other can be accessed for data communication.
  3. It provides high privacy and security.
  4. Fault identification is easy because of point-to-point connection.

Disadvantages of Mesh Topology:

  1. Mesh topology requires high NO: of cables and I/o ports for the communication.
  2. Installation is very difficult in mesh topology, as each node is connected to every node.
  3. Mesh topology is costly compared to the other network topologies i.e. star, bus, point to point topology.

Due to these reasons a mesh topology is usually less implemented in realistic networks.
