Ring Topology

In a ring topology, each node is connected to two other nodes and creates a circular form of connection. 

Traffic flow can be either unidirectional or bidirectional. There is an option for setting the flow of traffic either clockwise or anti-clockwise for unidirectional flow. Let’s say node 1 and node 4 want to share some data, and the traffic flow is set to unidirectional with a clockwise flow. Traffic from node 1 will travel through nodes 2, 3, and finally node 4. For the anticlockwise direction, traffic will flow from node 1 to node 6, node 5, and node 4.

Similar to the bus topology, only a single node can transmit the data.  A token is assigned to each node, and it determines when the node can start transmitting the data. 


  • Easy to manage
  • Performance is better than bus topology.
  • Does not use a central device to manage connectivity.
  • Easy to identify and isolate faults.
  • Very orderly network where every device has access to the token and the opportunity to transmit


  • Bandwidth is shared.
  • Failure of a node or cable can isolate the entire network. 
  • All nodes should be up to allow communication between nodes. 
  • Addition and removal of any node will impact the entire network.
