DATA TRANSMISSION METHOD AND COMMUNICATIONS DEVICE

摘要

Embodiments of the present invention provide a data transmission method and a communications device. A second-version hypertext transfer protocol (HTTP/2) adaption layer is arranged between an application layer of a protocol stack and a multipath data transfer protocol (MPTCP) layer, all frames belonging to a same HTTP/2 flow are allocated to a same MPTCP subflow for transmission. The data throughput is great, the system robustness is good, and transmission performance of HTTP/2 flows is improved.
