• On token-passing networks, beaconing is a technique for monitoring the status of the token-passing process. To ensure that token passing is working effectively, beaconing is utilised in token ring and Fiber Distributed Data Interface (FDDI) networks.
• Every station on a token-passing network like FDDI is responsible for monitoring the token-passing process's status.
• When a station identifies a defect, it begins putting beacons on the ring. When a beacon is detected by the next station on the ring, it begins planting beacons on the ring, and the first station stops sending them.
