1. A method for transmitting data packets in multiple links, comprising:
determining a first failed data packet in a transmission window, wherein the first failed data packet is a data packet whose transmission does not succeed and which has a smallest sequence number in the transmission window;
determining whether a difference between the sequence number of the first failed data packet and a start sequence number of the transmission window is less than or equal to a first preset threshold;
determining whether the transmission window is in a data packet full condition based on the difference being less than or equal to the first preset threshold;
duplicating the first failed data packet in the transmission window to at least one other link of the multiple links based on the transmission window being in the data packet full condition, wherein the multiple links comprise a first link on which the first failed data packet is transmitted and the at least one other link; and
retransmitting the first failed data packet on the at least one other link and the first link.
