Abstract: A control apparatus, comprises: a traffic information collection unit that collects per-flow traffic information from a control target node for performing packet processing per flow; a traffic analysis unit that performs totalization per flow based the traffic information to determine a flow whose traffic is expected to increase and a corresponding time period; and a presetting unit that presets control information for processing the determined flow in a node on a path that corresponds to the flow whose traffic is expected to increase during the determined time period.

Abstract: A communication node comprises: a first table for matching against first information in a header of a packet received and deciding an attribute or a right of a source of the packet; a second table for matching against second information in the header of the packet received and finding content of processing for the packet from the source of the packet having the attribute or the right as decided using the first table; and a packet processing unit that, on receipt of the packet, decides the attribute or the right of the source of the packet, using the first table, and that thereafter finds, using the second table, the content of processing for the packet from the source of the packet having the attribute or the right as decided using the first table.
