Communication network control system, central communication control device, communication control method, and communication control program

A communication network control system comprising:

• a plurality of communication control devices provided in a plurality of apparatuses that are arranged in a geographically dispersed manner and that are included in a communication network to which the plurality of apparatuses are connected, the communication control devices being configured to control communication of each of the plurality of apparatuses in accordance with distributed communication control information;
• and
• a central communication control device configured to distribute communication control information to the plurality of communication control devices,
• wherein the central communication control device
• collects event information from a source outside of the communication network, where the event information identifies an event and links position information for where the event occurs in the communication network to the event linked to position information,
• converting the position information for the events into an area code,
• determines an area in the communication network where an amount of communication in the communication network will likely increase by linking the area code for a given event to one or more network addresses in the communication network,
• generates communication control information that places a priority on communication in the area in response to a determination that the amount of communication increases in the area of the communication network, and
• distributes the generated communication control information to the plurality of communication control devices, where the communication control information includes area codes for specifying areas in the communication network where the amount of communication will likely increase and the area codes are allocated to subnet IDs in a network address of a data packet.
