1. An electronic control unit connected to an in-vehicle network in an in-vehicle network system, the in-vehicle network system including a plurality of apparatuses that performs communication of frames via the in-vehicle network, the electronic control unit comprising:
a first control circuit; and
a second control circuit,
wherein the first control circuit is connected to the in-vehicle network via the second control circuit,
wherein the first control circuit performs a first determination process on a frame that is transmitted to the in-vehicle network, and determines conformity of the frame with a first rule,
wherein, upon determining that the frame conforms to the first rule, the first control circuit transmits the frame to the second control circuit,
wherein the second control circuit performs a second determination process on the frame, that is received from the first control circuit, and determines conformity of the frame with a second rule,
wherein, upon determining that the frame conforms to the second rule, the second control circuit transmits the frame to the in-vehicle network, and
wherein the second control circuit performs the second determination process on the frame, that is received from the first control circuit, after the frame is received by the second control circuit from the first control circuit.
