What is Fully-Interconnected Network Topology?

Computer NetworkNetworkOperating System

In this topology, every node is connected using a separate physical link. Each computer network has a direct dedicated link, i.e., point to point connection with all other network computers. Each computer has its control and decision power for communication priorities.

It is a very reliable topology because any transmission line’s failure only affects the transmission between the two connected computers. The communication or message is high-speed and has mostly a full-duplex mode, but at the same time, a large number of communication lines make the network costly as for nodes lines or links are required.


The advantages of the tree network topology are as follows −

  • The connection is very quick between any two nodes.
  • The topology is very reliable as the failure of any line does not affect another link.
  • The control among nodes is distributed.
  • Each node does not require routing capability.


The disadvantages of the tree network topology are as follows −

  • It is a very costly topology as if there are n nodes in the network, each node requires (n – 1) lines/links resulting in a total requirement of $n(\frac{n-1}{2})$links.
  • If a new node is joined to the network, the cost raises multiple times depending on the total existing nodes and that number of lines are required.
