Abstract
A packet recovery method of the present invention is a packet recovery method upon loss of a plurality of packets transmitted from a first nodeto second nodethrough a network in the order of sequence numbers assigned to each of said packets, wherein second node, upon detection of a loss of a packet transmitted from first node, transmits an acknowledgement message, including a sequence number of a packet whose receipt has been confirmed or whose loss has been detected and including information on the lost packet, to first nodethrough the network. Then, first node, upon receipt of the acknowledgement message from second node, assigns a sequence number that is different from that of any of the plurality of packets to a retransmission packet which is a packet to be retransmitted, and subsequently, transmits an acknowledgement-to-acknowledgement message attached to the retransmission packet through the network for notifying that the acknowledgement message has been received to second node
