Abstract

The present application provides a data transmission method, device, and system. The method includes: when the data packet sent from the sending end to the receiving end is lost, the receiving end sends the data packet corresponding to the lost data packet to the sending end and the transit node respectively. Negative acknowledgment, when one of the sending end and the receiving end is a user end, the other is the main transmission node in the transmission network of the user end, and the transfer node is the main transmission node in the transmission network except the main transmission node. Other transmission nodes other than the transmission node are configured to forward the negative acknowledgment to the sending end after receiving the negative acknowledgment; when receiving the negative acknowledgment, the sending end sends the receiving end and the transit node respectively For the lost data packet, the transit node is further configured to forward the lost data packet to the receiving end after receiving the lost data packet. The present application provides an embodiment, which can improve the data transmission quality between the transmission node and the user terminal in the transmission network of the user terminal.

Description

technical field [0001] The present application relates to the technical field of communication, and in particular to a data transmission method, device and system. Background technique [0002] In the Internet system, the transmission quality between the client and other devices is a key factor affecting the user service experience. In related technologies, in order to improve the transmission quality, a transmission node is assigned to the user terminal in the transmission network of the user terminal, and a "user terminal-other device" link is divided into "user terminal-transmission node" and "transmission node-other device" Two links, enabling the replacement of one poor-quality link with two better-quality links for higher link capacity and better coverage. However, data packet loss still occurs between the transmission node and the user end, and the quality of data transmission cannot be guaranteed. Contents of the invention [0003] The present application provide...
