Ring network

Ring network information

What is a ring network?

A ring network is a network topology in which each node connects to exactly two other nodes, forming a single continuous pathway for signals through each node - a ring. Data travel from node to node, with each node along the way handling every packet.

Disadvantages



Disadvantages


  • One malfunctioning workstation can create problems for the entire network. This can be solved by using a dual ring or a switch that closes off the break.
  • Moving, adding and changing the devices can affect the network
  • Communication delay is directly proportional to number of nodes in the network
  • Bandwidth is shared on all links between devices
  • More difficult to configure than a Star: node adjunction = Ring shutdown and reconfiguration

Advantages


Advantages

  • Very orderly network where every device has access to the token and the opportunity to transmit
  • Performs better than a bus topology under heavy network load
  • Does not require a central node to manage the connectivity between the computers
  • Due to the point to point line configuration of devices with a device on either side (each device is connected to its immediate neighbor), it is quite easy to install and reconfigure since adding or removing a device requires moving just two connections.
  • Point to point line configuration makes it easy to identify and isolate faults.
