Abstract
A system for identifying the source of a loop in a ring network is provided. During operation, the system receives a first message, which indicates the presence of a looped packet, from a network device of the ring network. The system receives a second message from a respective network device with an uplink to an external network. The second message can include traffic information associated with the uplink. Upon determining based on the first message that a local link intended to be disabled is active, the system determines that a loop is present in the ring network. Upon determining that a plurality of uplinks are active based on the second message, the system determines that a loop is present in the uplinks. If a loop is not present in the ring network or in the uplinks, the system determines that a loop is present in the external network.
