Abstract: 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.

Abstract: The present disclosure provide a method for creating a stream forwarding entry includes: receiving, by a data communication device, a packet; making statistics on the received packet to obtain a statistical value of a stream corresponding to the packet; judging whether the statistical value of the stream exceeds a preset threshold value; and if exceeds the preset threshold value, creating, by the data communication device, a stream forwarding entry for the stream corresponding to the packet, and performing stream forwarding for subsequent packets of the stream according to the stream forwarding entry. Through the present disclosure, the number of stream forwarding entries in a stream table is reduced, the required storage space is reduced, and the maintenance of the stream table is simplified; moreover, the data communication device is not vulnerable to attacks of denial of service and is highly secure.

Abstract: This application provides a data transmission method and a apparatus. 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.

Abstract: 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.
