摘要

This transmission device has a detection unit, a generation unit, and a transmission unit. When the detection unit has detected a match between the communication rules for a message that has been broadcast transmitted to a network by another transmission device and the communication rules of a message that the present transmission device broadcast transmits to the network, the generation unit generates an abnormality notification message. Then, the transmission unit broadcast transmits the abnormality notification message to the network.
