Mesh Topology

A mesh topology is a network topology in which each communicating node is directly connected to all other nodes.
Mesh topology provides each device with a point-to-point connection to every other device in the network. These are most commonly used in WAN's, which connect networks over telecommunication links. Mesh topologies use routers to determine the best path.
Mesh networks provide redundancy, in the event of a link failure; meshed networks enable data to be routed through any other site connected to the network. Because each device has a point-to-point connection to every other device, mesh topologies are the most expensive and difficult to maintain.


  • Dedicated links eliminate congestion due to excessive traffic.
  • Robust as one damaged link will not cripple the network.
  • Point-to-point connections make fault isolation and identification simple.

  • High number of connections requires large number of network ports and large amounts of cabling.
  • Wiring bulk may exceed space available.
  • Duplication of hardware becomes expensive
