Abstract

The invention discloses a data transmission method. The method comprises the following steps that: a first terminal acquires first data to be transmitted to a second terminal, the first data are generated by a first application, the QoS information of each transmission path in N available transmission paths is acquired, and N is an integer greater than 1; the N available transmission paths are communication paths between the first terminal and the second terminal, and then the first terminal determines a first transmission path of which the QoS information satisfies a transmission condition from the N transmission paths; and the first terminal transmits the first data through the first transmission path. According to the scheme provided by the embodiment of the invention, the terminal candetermine the transmission path for transmitting the data generated by the application based on the QoS information of each transmission path, so that the requirement of data transmission on the QoS is met.

Description

technical field [0001] The present application relates to the technical field of communication, and in particular to a data transmission method, terminal and communication system. Background technique [0002] In the Internet or data center network, there are often equal-cost routes or multiple communication paths similar to equal-cost routes between the source node and the destination node. Multiple communication paths can be used for fault migration or to improve network transmission performance. For example, when the wireless fidelity (wireless fidelity, WiFi) signal is not good, the mobile phone transmits data through the fourth generation (4th generation, 4G) network, so as to realize uninterrupted data transmission. [0003] At present, there are also some protocols that support multi-path transmission, such as multipath transmission control protocol (multipath transmission control protocol, MPTCP), stream control transmission protocol (stream control transmission prot...
