Ring Topology

In a ring topology, the host communicates with all nodes through the most effective path. You must use an external switch in a ring topology. You must configure the network properly with a recommended external switch before creating redundant links in the network.

Advantages:

• Failure of any single Ethernet cable does not disrupt network communication
• Additional nodes or heavier network traffic affects network performance less than the line topology
• Simple installation
• Ideal for a local networking solution

Disadvantages:

• Network traffic patterns can make troubleshooting difficult
• Requires an external switch
