Abstract
(EN)

PROBLEM TO BE SOLVED: To transmit failure information through a network, even when a data link capable of transferring data is not formed on a network physical layer, data cannot be transferred/received normally through a data link layer, or a part of the physical layer has a failure.

SOLUTION: The data transfer device includes: a control information generating section which generates a second control information delivered in the physical layer of a communication line on the basis of an error in the physical layer of the communication line or an error in a data link layer which is structured by using a first control information in the physical layer; and a transmission section which transmits the second control information generated by the control information generating section through the physical layer of the communication line when communication cannot be made in the data link layer of the communication line.

【課題】ネットワークの物理層上にデータ転送可能なデータリンクが形成されていない場合、あるいは、データリンク層を介してデータの送受信を正常に行えない場合、あるいは物理層の一部に故障がある場合でも、ネットワークを介して障害情報を送信可能とする。
【解決手段】データ転送装置は、通信回線の物理層のエラーまたは物理層の第1の制御情報を用いて構築されるデータリンク層のエラーに基づいて、通信回線の物理層で授受される第2の制御情報を生成する制御情報生成部と、物通信回線のデータリンク層での通信ができない場合に、通信回線の物理層を介して、制御情報生成部が生成した第2の制御情報を送信する送信部と、を備える。
