Patent number: 11509597Abstract: Embodiments of the application provide a data transmission method and a device. A sending device periodically obtains a first packet sequence number and a second packet sequence number. The first packet sequence number is a maximum value in packet sequence numbers respectively corresponding to packets that belong to a first data flow and that are received by a receiving device through a first data channel in a statistics period. The second packet sequence number is a maximum value in packet sequence numbers respectively corresponding to packets that belong to the first data flow and that are received by the receiving device through a second data channel in the statistics period. The sending device updates a packet cache queue of: the first data channel, the second data channel, or both the first and the second data channels, based on the first packet sequence number and the second packet sequence number.Type: GrantFiled: March 24, 2021Date of Patent: November 22, 2022Assignee: HUAWEI TECHNOLOGIES CO., LTD.Inventors: Zhigang Huang, Xijin Tan, Xiaoyang Qu, Jian Chen
