Abstract: A C-plane device in a path control system comprises: a storage unit storing designation information designating search key information of a node used as a search key determining a transmission destination and part information indicating a packet part in which the search key information is included; and a setting unit, in a case in which a new node is connected to the U-plane device, acquires node information relating to the new node, extracts search key information of the new node on the basis of the acquired node information and the stored to designation information, and, in a case in which, in a packet received by the U-plane device, the search key information of the new node is included in a packet part indicated by the part information, sets a transmission destination of the packet for each of at least a part of U-plane devices.
