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.

Abstract: An integrated control device, to implement automatic address assignment in a path spanning two or more administrative domains, and to implement communication between a plurality of administrative domains, acquires definition information that defines protocols used in each administrative domain from an inter-administrative domain communication protocol stack list table, acquires available addresses of each protocol in each administrative domain which can be used for communication between the respective administrative domains from an available address range table, acquires a communication route from a starting point administrative domain to an ending point administrative domain, specifies domains that use the respective protocols on the communication route by using the definition information, assigns protocol information such as available addresses of each protocol between the specified domains by using an available address range table and notifies the assigned address to each domain.
