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.
