A method and system in a data processing system are disclosed for the retransmission of only a portion of a data packet which had originally been transmitted incorrectly. A first data link is established between a first computer system and a second computer system. In response to the establishment of the first data link, a second data link is established between the first and second computer systems, whereby the first and second data links are related. A plurality of data packets are transmitted from the first computer system to the second computer system utilizing the first data link. Each of the data packets includes a plurality of segments. A determination is made whether each of the plurality of data packets is received correctly. In response to a determination that one of the plurality of data packets is received incorrectly, a portion of the data packet which was transmitted incorrectly is determined. Only the incorrectly transmitted portion of the data packet is then retransmitted by the first computer system utilizing the second data link.
