NETWORK CONTROL APPARATUS, NETWORK SYSTEM, NETWORK CONTROL METHOD, AND PROGRAM

摘要

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.

1. A network control apparatus, comprising:
a network management unit that holds topology information and flow information about a network including a plurality of switches; a network division unit that divides the plurality of switches into a core switch(es) and an edge switch(es) based on the topology information; a core network management unit that holds topology information and flow information about a core network including the core switch(es); an edge network management unit that holds topology information and flow information about an edge network including the edge switch(es); a core control logic that generates flow information about the core network 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 about the edge network based on the topology information about the edge network and stores the flow information in the edge network management unit, wherein when the core control logic generates the flow information about the core network or when the edge control logic generates the flow information about the edge network, the network division unit updates flow information held in the network management unit.
