Patent number: 11785120Abstract: A data transmission method and an apparatus are provided. The method includes: when determining that a first data stream satisfies a transmission optimization enabling condition, a first transmitting end TE1 sends a transmission optimization enabling notification to a first receiving end RE1, where the transmission optimization enabling notification is used to indicate the RE1 to skip sending, to the TE1, an acknowledgment packet used to acknowledge that a data packet of the first data stream is already received by the RE2. The TE1 receives a data packet Data2 in a second protocol format from the TE2. The TE1 sends a data packet Data1 in a first protocol format to the RE1. The TE1 receives an acknowledgment frame Ack1 in the first protocol format from the RE1. The TE1 constructs an acknowledgment packet Ack2 in the second protocol format based on the Ack1, and sends it to the TE2.Type: GrantFiled: July 14, 2021Date of Patent: October 10, 2023Assignee: Huawei Technologies Co., Ltd.Inventors: Bo Zhang, Qiujie Fu, Zhigang Huang, Fangzhou Yu

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

Patent number: 11502962Abstract: Embodiments of this application disclose a method, an apparatus, and a system for implementing data transmission. The method includes: obtaining, by a sending device, a data packet in a target data flow; and sending the data packet through each of at least two physical links between the sending device and a receiving device, where the data packet sent through each of the at least two physical links includes a same sequence number. Because the data packet in the target data flow is sent through different physical links, not through only one physical link, when a transmission latency of the data packet is increased due to a bandwidth instability factor such as burst traffic or electromagnetic wave interference on any physical link, the receiving device can combine, into a target video flow, data packets that are sent through other physical links and that have a lower latency.Type: GrantFiled: March 24, 2021Date of Patent: November 15, 2022Assignee: HUAWEI TECHNOLOGIES CO., LTD.Inventors: Xiaoyang Qu, Zhigang Huang, Guang Chen, Jian Chen
