Mesh network

Scheme of a meshed network
Scheme of a fully meshed network

In a meshed network ( English mesh ), each of network nodes connected to one or more other. The information is passed from node to node until it reaches the destination. If every participant is connected to every other participant, one speaks of a fully meshed network.

General

Meshed nets are usually self-healing and therefore very reliable: If a knot or connection is blocked or fails, the net can knit itself around it. The data is redirected and the network is still operational.

The concept of meshed networks can be applied to wired and radio networks as well as to the interaction of programs. Mobile ad hoc networks (MANet), supported by many consumer devices, are a subset of mesh networks.

In large networks you often find a structure that is composed of several different topologies. The Internet is largely a meshed network, but there are still “main traffic arteries” (the backbone lines) that resemble a ring .

In the case of fully meshed networks with n nodes, the number of connections is ; this is also the upper limit of the number of connections in partially meshed networks.

advantages

  • Safest variant of a network
  • If a device or a connection fails, data communication is still possible by rerouting
  • Very efficient
  • Good load distribution
  • No central administration

disadvantage

  • High energy consumption
  • Comparatively complex routing required
  • Each end device works as a router and is therefore often active
  • The end devices should remain switched on if possible in order to guarantee the stability of the network
