Definition 1: A mesh topology is a network, where nodes are all connected to each other. The networks can be considered as one type of ad hoc network or example of ad hoc. Mobile ad hoc networks (MANET) and mesh networks are therefore closely related, but MANET also have to deal with the problems introduced because of the mobility of the nodes.

Definition 2: Mesh topology is where all computers/devices are interconnected with one another via cables. This topology is look alike star topology you can explore. It allows fast transmission between machines even one of the PC is disconnected or goes down from the circle. The topology can be used while you are in wireless network.

Mesh Topology Formula:

Formula to count full mesh topology:  n(n-1)/2

Mesh Topology Diagram:

Below is a graphical representation how a mesh topology is interconnected with each other. Incase any of the machine disconnected, no connection would be break. Communication with each other still remain connected.

Types of Mesh Topology

A mesh can be a full or partially connected. There are two types of mesh topology. They are introduced to implement in real life but according to the research they are not in used.

  1. Full Mesh topology
  2. Partial mesh topology

Full Mesh Topology

In full mesh, every computer in the network has a connection to each of the other computers via cable. The number of connections in this network can be calculated using the following formula (n is the number of computers in the network).

Partial Mesh Topology

In partial mesh, at least two of the computers in the network have connections to multiple other computers. Partially connected is an inexpensive way to implement redundancy in a network. There is no harm to implement partial topology because a primary computers or connections in the network fails, the rest of the network continues to operate normally.

Advantages and Disadvantages of Mesh Topology:


  • Manage high amounts of traffic, because multiple devices can transmit data simultaneously.
  • A failure of one device does not cause a break in the network or transmission of data.
  • Adding additional devices does not disrupt data transmission between other devices.


  • The cost to implement is higher than other network topologies, making it a less desirable option.
  • Building and maintaining the topology is difficult and time consuming.
  • The chance of redundant connections is high, which adds to the high costs and potential for reduced efficiency.
Can more devices be added in mesh:

Yes, we can add more devices; because it can be among routers only or among systems only, but in mesh computers more commuters can be added but not router as a part of it.

Is Mesh a LAN or WAN?

A mesh network is considered a local area network topology because every node connected via switch or bridge or connected directly to one another.

Why are Mesh network used?

Many of small organization of sometime large organizations used them but now a days we can considered it to be obsolete. The connectivity purpose of organizations are routers / hub/ switches.

Is there any other name of Mesh?

Yes, we call it mesh network.

Is Mesh Wired or Wireless?

Usually the topology set-up via wires but with wireless back-hauling it can be a wireless.

What is the formula for Mesh ?


Is mesh a hybrid?

Yes, It is.
