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 travels from node to node, with each node along the way handling every packet.
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.
- Reconfiguration for line faults of bidirectional rings can be very fast, as switching happens at a high level, and thus the traffic does not require individual rerouting.
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
