Abstract

A data transmission method, comprising: receiving a TCP data packet sent by a sending device (S110); generating ACK acknowledgement data according to the TCP data packet, and storing the ACK acknowledgement data to a transmission buffer (S120); and transmitting the latest ACK acknowledgement data in the transmission buffer to the transmission device (S130). Therefore, the stability and the transmission efficiency of data transmission between the transmitting device and the receiving device can be improved. The invention further provides a device, a system, terminal equipment and a storage medium.

Description

technical field [0001] This specification relates to the field of communication technologies, and in particular to a data transmission method, device, system, terminal equipment, and storage medium. Background technique [0002] The TCP / IP protocol is currently the most commonly used protocol in the communication network, and its characteristic is that the two parties in the communication need to shake hands and confirm to ensure the correct transmission of data packets. This requires that the two-way channels are kept unobstructed, otherwise it will cause congestion and disconnection. [0003] In the standard TCP protocol, the sending data buffer is a dynamically managed window mechanism. The sender manages its own sending buffer according to the receiver's ACK (Acknowledgment) information; when the receiver's ACK information is blocked, the data transmission between the sender and the receiver is unstable and the transmission efficiency is low. Contents of the invention...
