Answer: Ring topology has nodes connected in a circular manner, where each node is linked to exactly two other nodes, causing failure due to cable damage, node failures, power issues, configuration errors, and network congestion.
Causes of Failure in Ring Topology
Cause 1: Cable Damage
In many cases, if the cable which connects the two nodes in the ring topology is damaged, then it can lead to the communication failure between these nodes, which breakdowns or stops the entire network.
Cause 2: Node Failure
In the ring topology, if the node gets malfunctioned or filled, then it can break the continuity of the ring, which causes the communication breakdown.
Cause 3: Power Outages
The power outages or the fluctuations in the power can also affect the functioning of nodes in the ring topology, which actually leads to the temporary failure of the network in the ring topology.
Cause 4: Configuration Issue
If the configuration settings is been incorrectly done, then the communication errors and failures can be occurred in the ring topology.
Cause 5: Network Traffic Overload
In many of the cases, the high network traffic in the network can actually adequate bandwidth or capacity and congestion in the network can occur. This leads to various problems like delays, packet loss and also the potential failures in the network.
