Abstract: In a relay device, a transmitting/receiving unit of an ECU relay receives data. A first counter value is incremented if an amount of data received by the transmitting/receiving unit per unit time exceeds a first threshold.

The second threshold is greater than the first threshold. A control unit of a bus relay repeatedly monitors the first counter value. If the first counter value is incremented, the control unit shortens a cycle with which the second counter value is monitored.
