Mesh network topologies were used before switches were invented. At the time, it was a widely used topology and organizations preferred setting up mesh networks for communication between computers. At present some people still use a mesh topology for creating a small home network. With a mesh topology, every computer is connected in a point-to-point link with other computers. Each dedicated link carries traffic between the connected computers. Before setting up a big network one must measure how much equipment is required for making a mesh topology network. There is a particular formula for measuring the amount of equipment needed for a mesh topology.

The formula is given below:

The number of connecting devices is represented by “n” in the formula. The formula is n(n-1)/2 is for the number of links between computers, n-1 is used for finding the ports of the computers. Let us take an example for measuring the I/O ports and links between computers. For example, if you have five computers and want to create a mesh topology then this formula can be used to find out the number of ports and links required for creating the network.

Example:

No. of links = 5(5-1)/2 = 10
No. of I/O Ports = 5-1 = 4

1. Due to dedicated links to each computer there is an assurance that the load of data being transferred will be carried between the amount of computers and eliminates a traffic problem if data is shared.
2. Mesh topology is very strong and robust. If a link in the network gets down, the other connections and nodes don't get affected.
3. There is a high level of security and privacy due to the dedicated links
4. Mesh topology carries point-to-point links, by which it becomes easy to find faults.
