<p>A data transmission method and a data transmission apparatus are disclosed. The data transmission method includes: receiving a data packet sent by a sender, and recording information about the data packet received; sending the data packet received to a receiver through a protocol layer; looking up recorded information about data packets according to a data packet mapping after the protocol layer receives confirmation information of a data packet sent by the receiver to the sender, wherein the data packet mapping is a relation between a recorded data packet and a data packet received by the protocol layer; and constructing an Acknowledgement, ACK, destined for the sender according to information about the data packet obtained by the steps of looking up recorded information about received data packets.. Through the method provided herein, the apparatus constructs an ACK and sends it to the sender actively, thus improving the data transmission rate.</p> |
