Ring Network

What is ring network?

Advantages


  • . It Performs better than a bus topology under heavy network load
  • . It 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.

Ring Network definition

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

  • .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
