Abstract
Anode device includes a transmitter and a processor. The transmitter transmits an inspection frame used in inspecting a status of a route from a source node device to a destination node device. The processor generates a first inspection frame and selects a first node device to which the transmitter transmits the first inspection frame from among candidates for a node device to which a frame addressed to the destination node device is to be forwarded. The processor judges whether a transmission of the first inspection frame has been successfully performed. When the transmission of the first inspection frame has failed, the processor generates a second inspection frame which records a failure in a communication with the first node device. The processor selects a second node device to which the transmitter transmits the second inspection frame from among the candidates.
