Abstract:
According to the present invention, an assigning unit (11) assigns, to the header of a packet from a terminal accommodated in a first router (10) to a second router (40), information capable of specifying the interface between the terminal and the first router (10) as subscriber information. A transfer unit (32) transfers the packet destined to the first router (10) or the second router (40) to the VNF corresponding to the subscriber information of the packet, and transfers, to each router, the packet transmitted from the VNF. A management unit (42) manages an entry, in which information specifying a transmission source or destination of the packet from the first router (10) is associated with subscriber information assigned to a packet, together with an NAPT flag that determines whether to use an IP address as a key, or the IP address and a port number as the key. An assigning unit (43) assigns, to the header of the packet to the first router (10), subscriber information managed by the management unit (42).
