1. A communication control system, comprising:

  • a switch node configured to carry out processing of each of received packets based on a flow entry defining a rule and an action to uniformly control the packets; and

    a control server configured to set the flow entry into a flow table of the switch node,wherein the switch node comprises;

    means for connecting a plurality of processors including large-capacity memories and a plurality of extended network interfaces by a multi-route compatible Peripheral Component Interconnect (PCI) express switch, to configure switch ports including the plurality of extended network interfaces;

    means for carrying out load distribution transfer processing from the plurality of extended network interfaces to the plurality of processors and carrying out high-speed packet processing through multiple processing by using the plurality of processors;

    means for configuring a large-capacity flow table in the switch node which is software-based, by using a large-capacity memory space of the plurality of processors;

    means for receiving the packets by either of the plurality of extended network interfaces; and

    means for determining distribution processing to the plurality of processors by using a hash function in one of the plurality of extended network interfaces which receives the packets, and carrying out high-speed processing through the load distribution processing of software packet processing and multiple processing of the packet processing in the plurality of processors.
