Mesh Topology

In mesh topology, each node is connected to more than one node to provide an alternative route in the case the host is either down or too busy.

The mesh topology is an extension to P-P network.

The mesh topology is excellent for long distance networking because it provides extensive backup, routing and pass-through capabilities.

Mesh topology is too popular in WAN.

The wiring of mesh topology are too complicated because when we connect all devices to all other devices, then there is a requirement of more cables.

There is a two format of mesh topology:

  • full mesh - all devices are directly connected to all other devices.
  • partial mesh - some devices are directly connected to all other devices but some devices are not connected directly to other devices.

Since mesh topology is a popular technique of WAN, here, in place of computer there is a routers connected with each other.

If the communication between the sides are so important, and if we can't want to breakdown this. Then we can use mesh topology between the routers.

Advantages of mesh topology

There is a redundant path for one place to other (one device to other).

Disadvantages of mesh topology

We can't take full advantages of the path and to implement the mesh topology, there is to complicated. Because for every new connection, every new expansion, we have require new network interface card and new connectivity cable.
