What is the name of the network topology in which there are bidirectional links between each possible node?
Ring network topology in which there are bidirectional links between each possible node.
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.
Disadvantages of ring topology. All data being transferred over the network must pass through each workstation on the network, which can make it slower than a star topology. The entire network will be impacted if one workstation shuts down.
In wide area networks (WAN) and meteropolitan area networks (MAN), a ring topology is used to as the topology for the backbone (sometimes called a city ring) to connect the customers. In that case the ring is used in both directions to have two distinctive paths to the public switch.
