Abstract

Embodiments of this application disclose a data transmission method and apparatus and a data receiving method and apparatus. The data transmission method comprises: responding to a data packet received from a first device, and sending a receiving acknowledgment to the first device; and sending the data packet to a second device, wherein the second device is a target device of the data packet. According to the method and apparatus in the embodiments of this application, a middle device responds to receiving of a data packet and sends a receiving acknowledgment to a device of a sending end, causing that the device of the sending end may send a next data packet without waiting for a receiving acknowledgment that is from a device of a receiving end and that is transmitted by using a relatively long link, which greatly shortens a transmission distance of the receiving acknowledgment, reduces delay of sending of a data packet by the sending end, and improves a data sending rate of the device of the sending end, thereby improving data transmission performance.

sending the second identification information to the second device.

4. The method of claim 3, wherein the sending the second identification information associated with the data packet to the second device comprises:

sending the second identification information by adding the second identification information to a header of the data packet.

5. The method of claim 3, wherein the second identification information comprises a HASH value that is associated with a serial number of the data packet and a second type, wherein the second type is sent by using the data packet.

6. The method of claim 3, wherein the method further comprises:

responding to a receiving acknowledgment that is received from the second device and that is associated with the data packet, and releasing storage space for temporarily storing the data packet.

7. The method of claim 3, wherein the method further comprises:

responding to a not-receiving acknowledgment that is received from the second device and that is associated with the data packet, and retransmitting the data packet to the second device.

8. The method of claim 3, wherein the method further comprises:

responding to a receiving acknowledgment that is not received from the second device within a first preset time and that is associated with the data packet, and retransmitting the data packet to the second device.

9. The method of claim 1, wherein the method further comprises:

responding to that the data packet from the first device is not correctly received, and sending a not-receiving acknowledgment to the first device.

10. The method of claim 1, wherein the receiving acknowledgment is a Media Access Control MAC layer message or a Transmission Control Protocol TCP layer message.

11. The method of claim 9, wherein the not-receiving acknowledgment is a Media Access Control MAC layer message or a Transmission Control Protocol TCP layer message.

12. A data receiving method, wherein the method comprises:

receiving a data packet; and

sending a receiving acknowledgment associated with the data packet and first identification information associated with the data packet, wherein

the first identification information is used to instruct not to forward the receiving acknowledgment.

13. The method of claim 12, wherein the method further comprises:

responding to that the data packet is not correctly received, and sending a not-receiving acknowledgment associated with the data packet and the first identification information associated with the data packet.

14. The method of claim 12, wherein the method further comprises:

receiving second identification information associated with the data packet; and

generating the first identification information based on the second identification information.

15. The method of claim 14, wherein the second identification information comprises a HASH value that is associated with a serial number of the data packet and a second type, wherein the second type is sent by using the data packet;

and

the first identification information comprises a HASH value that is associated with the serial number and a first type, wherein the first type is a receiving acknowledgment.

16. The method of claim 12, wherein the sending a receiving acknowledgment associated with the data packet and first identification information associated with the data packet further comprises:

sending the first identification information by adding the first identification information to the receiving acknowledgment.

17. The method of claim 12, wherein the receiving acknowledgment is a Transmission Control Protocol TCP layer message or a Media Access Control MAC layer message.

18. The method of claim 13, wherein the not-receiving acknowledgment is a Transmission Control Protocol TCP layer message or a Media Access Control MAC layer message.
