Mesh topology

3) Mesh topology  

This topology is unique, and a true mesh topology is practically none exists. Most of the network that claims to be mesh topology to be mesh topology   is actually partial meshes. In a true, mesh each network devices must have a separate point-to-point connection to every devices in the mesh. For a three node mesh there are three connections, for four nodes there are 6 connections, in 5 nodes there are 10 connection and so on.

                It is extremely very useful when you want to be absolutely certain that data from one network node will reach any other network node in the mesh.

                If a single point-to-point connection fail, the data can travel through a different node and reach it’s final destination.
