Mesh Topology

Defination:

  • In this topology each node or station is connected to every other station.
  • Two nodes are connected by dedicated point-point links between them. So the total number of links to connect n nodes = n(n-1)/2; which is proportional to n2.
  • Media used for the connection (links) can be twisted pair, co-axial cable or optical fiber

The key characteristics of this topology are as follows:

  • Fully connected
  • Robust
  • Highly reliable
  • Not flexible
  • Poor expandability

Advantages:

  • Provides redundant paths between devices
  • The network can be expanded without disruption to current uses

Disadvantages: 

  • Complicated implementation
  • Requires more cable than the other LAN topologies
