  • Data transmission method and apparatus
    Patent number: 8630203
    Abstract: A data transmission method includes receiving a data packet sent by a sender and recording information about the data packet received, sending the received data packet 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. The data packet mapping is a relation between a recorded data packet and a data packet received by the protocol layer. The method further includes constructing an acknowledgement destined for the sender according to information about the data packet obtained by the steps of looking up recorded information about received data packets.

  • DATA TRANSMISSION METHOD AND APPARATUS
    Publication number: 20120039249
    Abstract: 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.
