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 TEsends a transmission optimization enabling notification to a first receiving end RE, where the transmission optimization enabling notification is used to indicate the REto skip sending, to the TE, an acknowledgment packet used to acknowledge that a data packet of the first data stream is already received by the RE. The TEreceives a data packet Datain a second protocol format from the TE. The TEsends a data packet Data1 in a first protocol format to the RE. The TEreceives an acknowledgment frame Ack1 in the first protocol format from the RE. The TEconstructs an acknowledgment packet Ackin the second protocol format based on the Ack1, and sends it to the TE

Data transmission method and related apparatus

An access point (AP) device comprising a controller configured to monitor bandwidth allocated by the AP device to a plurality of data flows directed to a plurality of wireless clients using a supported AP device, receive from the supported AP device a message indicating a degradation of a quality of service (QoS) level of the supported AP device, and adapt, in response to the message, a bandwidth allocated to a data flow which is forwarded to the supported AP device.

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.

Data transmission method and device

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.
