A storing unit stores therein packets included in packet communication signals received before and after issuing the retransmission request. A setting unit sets an order of transferring the packets stored in the storing unit to a control unit in an order of receiving the packets without a fail. A transferring unit transfers the packets stored in the storing unit to the control unit in the order set by the setting unit.
