   • Rather than using a star, bus or ring topology, each node is connected to one or more other nodes

       • If any node or connection becomes unavailable, the message can simply take a different route
   • Ring Topology: Computers are connected to each other in a ring. Communication only goes in one direction. Each computer receives a message, and if it is not the intended recipient, passes it on to the next computer. No central cable, each connection is between two computers.
