1. A data transmission method comprising:
receiving, by a multipath proxy gateway, indication information from a multipath management device, wherein the indication information indicates that the multipath proxy gateway is allocated to a multipath proxy client for multipath data transmission;
establishing, by the multipath proxy gateway, at least two multipath data subflows between the multipath proxy gateway and the multipath proxy client;
establishing, by the multipath proxy gateway based on a first internet protocol (IP) address of the multipath proxy client, a transmission control protocol (TCP) connection to an application server to be accessed by the multipath proxy client; and
performing, by the multipath proxy gateway, data transmission through the TCP connection and the at least two multipath data subflows.
