Abstract
According to one embodiment, a control device is for controlling a plurality of nodes configuring a dual ring network. Each of the nodes includes: a communicator configured to be capable of transmitting/receiving a frame to/from an adjacent node; a first counter configured to perform counting up when a normal frame is received via the communicator; and a second counter configured to perform counting up when an abnormal frame is received via the communicator. The control device includes a controller configured: to identify, when an abnormal frame is transmitted/received in the dual ring network, a terminal node of the dual ring network from the nodes based on values of the first counter and the second counter of each of the nodes; and to identify an abnormal part in the dual ring network based on the value of the second counter by using the identified terminal node as a starting point.
