Data Transmission Method And Apparatus

The present disclosure relates to data transmission methods. One example method includes receiving, by a receive end, at least two streams from a transmit end, where each stream of the at least two streams includes a plurality of data packets, each data packet carries a stream identifier of a stream to which the particular data packet belongs and a stream data sequence number, and the stream data sequence number indicates a sequence of the particular data packet in the stream to which the particular data packet belongs, for at least one of the at least two streams, determining, by the receive end, that a data packet whose stream data sequence number meets a sequential condition has been received, and submitting, by the receive end, the data packet whose stream data sequence number meets the sequential condition.
