Abstract

A network control device includes a network database and a switch controller. The network database stores topology information representing a network, and network flow information representing a data forwarding rule in the network. The switch controller generates the topology information by taking a plurality of switch devices included in the network as nodes and stores the generated topology information in the network database, generates switch flow information that defines an action of each of the plurality of switch devices, based on the network flow information stored in the network database, and sets the switch flow information into a corresponding one of the plurality of switch devices.
