Ring Topology




Introduction

In a ring topology, each device has a dedicated point-to-point connection with only the two devices on either side of it. A signal is passed through the ring in one direction, from device to device, until it reaches its destination.

 

Today, the need for higher-speed LANs has made this topology less popular.


Advantages of Ring topology

A ring is relatively easy to install and reconfigure as all the devices are connected to its two immediate neighbors. To add or delete a device requires changing only two connections.

 

Fault isolation is simplified as, a signal is circulating at all times. If any of the devices is not receiving a signal within a specified period, it can issue an alarm. The alarm alerts the network operator to the problem and its location.

Disadvantages of ring topology:

Media and traffic puts a limit on maximum ring length

 

Unidirectional traffic can be a disadvantage also as in a simple ring, a break in the ring can disable the entire network. This disadvantage can be solved by using a dual ring.
