PROBLEM TO BE SOLVED: To manage a wide area network (WAN) and a NW function cloud as separate networks, with network control in coordination with each other.SOLUTION: An edge switch connected to a WAN terminal notifies a WAN controller of the IP address of the terminal. The WAN controller stores the terminal IP address into terminal information storage means, notifies a cloud controller of the terminal IP address and contract service information, and generates a flow entry to notify the edge switch. The cloud controller stores the terminal IP address and the contract service information, acquired from the WAN controller, into flow management information storage means, and generates a flow entry to notify the gateway switch and the NW function server of the generated flow entry. The NW function server stores into a flow table the flow entry received from the cloud controller. |
