Abstract: A communication control apparatus according to the present invention is connected between a core node which processes received packets in accordance with a specified flow and a control apparatus which controls the core node, controls each of the core nodes existing in an aggregated network into which one or more the core nodes are aggregated, and converts an aggregated flow specified for an aggregated network and received from the control apparatus to a real flow specified for each of the core nodes in the aggregated network based on connection relationships between the core nodes in the aggregated network, information specifying a real port which is a port through which the core node in the aggregated network is connected to a device outside the aggregated network and a real node which is the core node having the real port for each the aggregated networks.

Abstract: This vehicle guidance system carries out guidance of vehicles that are traveling on roads making up a road network, the vehicle guidance system being provided with: a flow detection unit that detects the flow of vehicles on each of the roads making up a road network, and generates flow information indicating the detection result; a storage unit that creates associations between the flow information for the roads which has been generated by the flow detection unit, and road-identifying information indicating the corresponding roads, and storing the information; a decision unit that, for each of the roads making up the road network, specifies a candidate road that is a road which vehicles flow from the road in question, acquires the flow information that is stored in association with the road-identifying information indicating the specified candidate road in question, and based on the acquired flow information, decides on a flow increase or decrease policy of vehicles on the candidate road; and a guidance unit that carries out guidance of the vehicles, in accordance with the decision by the decision unit.
