摘要
A transmission device is located between a first node and a second node in a multi-layer network in which a path message is transmitted from the first node to the second node and a response message corresponding to the path message is transmitted from the second node to the first node. A transmission device includes: an upper layer switch that processes traffic in the upper layer; a lower layer switch that processes traffic in a lower layer; and a signaling processor that processes the path message and the response message. The signaling processor transmits a message for establishing a path in the lower layer to a node represented by node information added to the response message received from an adjacent node on a downstream side when the lower layer switch is not connected to a lower layer switch of an adjacent node on an upstream side.
