A buffer control apparatus (19, 21, 23, 25) comprises an input unit (25), a buffer unit (33), a same ID determination unit (31), an overwriting unit (29), a storage unit (29) and an output unit (35). When the same ID as the ID included in a message received by the input unit is present in the messages stored in the buffer unit, the overwriting unit (29) overwrites at least the data in the messages including that same ID with the data included in the message received by the input unit. |
