Abstract
A control apparatus comprises: a network management unit that holds topology information and flow information; a network division unit that divides a plurality of switches into a core switch(es) and edge switches; a core network management unit that holds topology information about a core network including the core switch(es); an edge network management unit that holds topology information about an edge network including the edge switches; a core control logic that generates flow information based on the topology information about the core network and stores the flow information in the core network management unit; and an edge control logic that generates flow information based on the topology information about the edge network and stores the flow information in the edge network management unit. When the flow information about the core network or the edge network is generated, the flow information held in the network management unit is updated.
