Abstract

The invention relates to a data transmission method and device, and the method comprises the steps: responding to a data transmission request from a user, and determining a preferred transmission protocol and an alternative transmission protocol from a plurality of available transmission protocols according to a quality evaluation parameter, wherein the quality evaluation parameter is obtained according to a historical downloading speed; and trying to establish a connection through the preferred transmission protocol prior to the alternative transmission protocol, so as to perform data transmission by using the preferred transmission protocol or the alternative transmission protocol according to a result of trying to establish the connection.

Description

technical field [0001] The present disclosure relates to the technical field of communications, and more specifically, to a data transmission method and device. Background technique [0002] In scenarios such as streaming of short videos, streaming of live broadcasts, or API requests, download speed is one of the key factors affecting user experience. In order to obtain a good download speed, there is currently a transmission protocol racing strategy, which can select a transmission protocol with a faster connection establishment speed for data transmission. For example, in Cronet, an independent open source network library based on the Chromium network stack, the communication between TCP (Transmission Control Protocol, Transmission Control Protocol) and QUIC (Quick UDP Internet Connection, UDP-based low-latency Internet transport layer protocol) is implemented. Protocol racing, which can switch to TCP in time when UDP (User Datagram Protocol) is restricted or blocked by t...
