A packet retransmission control device has a flow table and a processing determination unit. The flow table indicates, with respect to each of flows to which packets belong, retransmission management information for managing retransmission control. The retransmission management information includes, as a retransmission management parameter, at least one of a packet retransmission count and a delay excess count. The processing determination unit refers to the flow table to determine whether or not to apply the retransmission control to packets. Specifically, when receiving a packet from the upper layer, the processing determination unit refers to the flow table to obtain the retransmission management parameter associated with a flow to which the received packet belongs. If the retransmission management parameter is not more than a threshold value, the processing determination unit determines to apply the retransmission control to the received packet. If the retransmission management parameter exceeds the threshold value, the processing determination unit stops application of the retransmission control to the received packet. |
