Claim 8:
9. A communication control method executed by a communication control apparatus for implementing flow control of a software defined network (SDN), the communication control method comprising:
setting, when a packet of a flow that is not registered in transfer control information is detected when a plurality of packets that constitutes a flow is transferred, a destination resolution standby state for the flow in the transfer control information;
storing, into an evaluation queue, at least some of packets of the flow received when the flow is in the destination resolution standby state;
stopping, after destination resolution for the flow, a pipeline that processes a packet to be transferred;
outputting, after the destination resolution for the flow, any packets that belong to the flow and are stored in the evacuation queue;
setting, after the output of any packets that belong to the flow and are stored in the evacuation queue is completed, a valid state for the flow in the transfer control information; and
operating the pipeline after the output of any packets that belong to the flow and are stored in the evacuation queue is completed.
