[Problem to be Solved] Improving extensibility and flexibility of a network in which transfer through segment routing is executed. [Solution to the Problem] A transfer apparatus 1 configured to control transfer of a packet from a transmission source node to a destination node through segment routing includes: a storage unit storing node management information T1 indicating, for each node r1 to r3 that functions as a transmission source node or a destination node, an SID list acquisition method of the nodes r1 to r3; a packet reception unit 11 for receiving a reception packet from the destination node; an information setting unit 14 for, if a destination-side SID list acquisition method of the destination node and a transmission source-side SID list acquisition method of the transmission source node do not match each other based on the node management information T1, setting the information that is needed to execute the transmission source-side SID list acquisition method in the reception packet; and a packet transmission unit 15 configured to transmit the reception packet that was subjected to the setting to the transmission source node.
A transfer apparatus configured to control information that is needed in order to enable transfer of a packet from a transmission source node to a destination node through segment routing, the transfer apparatus comprising:
A transfer method of a transfer apparatus configured to control transfer of a packet from a transmission source node to a destination node through segment routing, wherein a storage unit of the transfer apparatus stores, for each node that functions as the transmission source node or the destination node, node management information indicating a segment identification (SID) list acquisition method of the node, and the transfer apparatus executes:
