To maintain high communication stability by preventing frequent re-transmissions while broadband communication is performed when a communication line including a plurality of different types of wireless communication is used.SOLUTION: A packet transmitting device 10 transmits data packets to a packet receiving device 20 using a first communication line and a second communication line whose communication possible area, where communication is possible, is smaller than that of the first communication line. The packet transmitting device includes: a communication status determination unit 102 that determines the communication status of the second communication line; a main/sub-line setting unit 103 that sets either the first communication line or the second communication line as a main communication line and the other as a sub-communication line; a transmission packet generation unit 104 that generates main data packets that are not subjected to band-limiting processing and sub-data packets that are subjected to band-limiting processing; and a transmission instruction unit 105 that gives instructions to transmit the main data packets through the main communication line and the sub-data packets through the sub-communication line.SELECTED DRAWING: Figure 2

    【課題】複数の異なる種類の無線通信を含む通信回線を用いた場合において、広帯域の通信を行いつつ、再送の頻発を防ぎ通信の高い安定性を維持する。【解決手段】第1の通信回線、及び第1の通信回線より通信が可能な領域である通信可能領域が狭い第2の通信回線を用いてパケット受信装置20へデータパケットを送信するパケット送信装置10であって、第2の通信回線の通信状態を判断する通信状態判断部102と、第1の通信回線又は第2の通信回線のいずれか一方を主通信回線、他方を副通信回線に設定する主副回線設定部103と、帯域制限処理を施さない主データパケット及び帯域制限処理を施した副データパケットを生成する送信用パケット生成部104と、主データパケットを主通信回線で、副データパケットを副通信回線で送信することを指示する送信指示部105と、を有する。【選択図】図2
