Abstract

Embodiments of the present invention provide an adaptive transmission method and device, which relate to the technical field of data transmission. The adaptive transmission method includes: obtaining a first uplink transmission rate and a second uplink transmission rate of a terminal; the first uplink transmission rate is the available uplink transmission rate, and the second uplink transmission rate is the uplink transmission rate required for the transmission service; if the first uplink transmission rate is lower than the second uplink transmission rate, an adaptive transmission strategy is determined, so The adaptive transmission strategy is used to instruct the terminal to reduce the size of the uplink acknowledgment data packet sent within a unit time period, so that the first uplink transmission rate can meet the requirement of the downlink transmission rate; according to the adaptive The transmission strategy performs data transmission with the peer. The problem of low downlink throughput caused by low uplink transmission rate in the related art is solved; data transmission can be adaptively performed according to an adaptive transmission strategy, thereby improving downlink throughput.

Description

technical field [0001] The embodiments of the present application relate to the technical field of data transmission, and in particular to an adaptive transmission method and device. Background technique [0002] Transmission Control Protocol (Transfer Control Protocol, TCP) and User Datagram Protocol (UserDatagram Protocol, UDP)-based low-latency Internet Transmission Protocol (Quick UDP Internet Connection, QUIC) are connection-oriented, reliable transport layer communication protocols. In order to ensure that no packet loss occurs, the sending end will assign a sequence number to each data packet when sending the data packet, and the receiving end will return a corresponding acknowledgment character (Acknowledgment, ACK) to the successfully received data packet. For services based on TCP or QUIC, the rate of downlink data transmission and the rate of uplink acknowledgment character transmission jointly determine the rate of the service. [0003] Usually, the downlink tra...
