Abstract
An efficient retransmission control method, whereby a wasteful retransmission request and retransmission of a packet are not carried out when packet loss occurs. A receiving unit sends the received retransmission request information to a retransmission determining unit. When receiving the retransmission request information, the retransmission determining unit reads out refresh data time information, packet type information of the packet for which a retransmission request is issued, and the time information thereof from a packet information monitoring unit. The retransmission determining unit makes a determination as to whether or not to issue a retransmission request using the read-out refresh data time information, packet type information of the packet for which a retransmission request is issued, and the time information thereof.
