DATA TRANSMISSION METHOD AND APPARATUS

The present invention relates to a data transmission method and an apparatus, and the method includes: receiving, by a first network node, quick user datagram protocol internet connection (QUIC) data packets sent by a second network node; sorting, by the first network node, the QUIC data packets, to obtain a sorting result; and sending, by the first network node, the QUIC data packets to a third network node based on the sorting result. In this way, when air interface resources between the first network node and the third network node are relatively insufficient, the second network node sorts the received QUIC data packets, and sequentially sends the QUIC data packets to the third network node based on the sorting result. This may greatly reduce a delay in receiving the QUIC data packet by the third network node, and further avoid disorder of the QUIC data packets in the first network node.
