PROBLEM TO BE SOLVED: To reduce a waiting time until transmission completion of data having a low priority.SOLUTION: A gateway device 1 includes: a storage part 4 for storing information 401 of a load cycle showing a fluctuation of a future load factor of each BUS and ID related information 402 including information of a priority of data transmitted in BUS 1 to 3; and a timing determination part 222 for determining transmission timing for transmitting reception data to a transmission destination BUS on the basis of the priority of the reception data and a transmittable time when data transmission becomes possible in a load cycle of the transmission destination BUS of the reception data. The timing determination part 222 determines a transmittable time as transmission timing of reception data if the transmittable time in a load cycle of a transmission destination BUS of the reception data is earlier by a prescribed time P than transmission timing of reception data having a priority higher than the reception data.SELECTED DRAWING: Figure 3

    【課題】優先順位の低いデータの送信完了までの待ち時間を減らす。【解決手段】ゲートウェイ装置1は、各BUSの将来の負荷率の変動を示す負荷周期の情報401と、BUS1〜3を送信されるデータの優先順位の情報を含むID関連情報402とを記憶する記憶部4と、受信データの優先順位と、受信データの送信先BUSの負荷周期においてデータ送信が可能となる送信可能時刻とに基づいて、受信データを送信先BUSに送信する送信タイミングを決定するタイミング決定部222と、を備え、タイミング決定部222は、受信データの送信先BUSの負荷周期における送信可能時刻が、当該受信データより優先順位が高い受信データの送信タイミングより所定時間P以上早ければ、当該送信可能時刻を受信データの送信タイミングとして決定する。【選択図】図3
