A data transmission method and related apparatuses are disclosed. A sanding node transmits a plurality of data packets to a receiving node at an initial transmission rate. Each data packet carries a random sequence number and a rolling sequence number. The random sequence number identifies a data part of the data packet, and the rolling sequence number indicates a transmission sequence of the data packet. The sending node receives a packet loss feedback from the receiving node. The packet loss feedback is generated after the receiving node detects a packet loss event according to rolling sequence numbers of received data packets. The sending node determines a random sequence number of a lost data packet based on the received packet loss feedback. The sending node transmits a replacement data packet to the receiving node. The replacement data packet carries a different rolling sequence number.

Method and apparatus for transmitting data packets using dual sequence numbers

A data transmission acceleration method and related apparatuses are disclosed. A sanding node transmits a plurality of data packets to a receiving node at an initial transmission rate. Each data packet carries a random sequence number and a rolling sequence number. The random sequence number identifies a data part of the data packet, and the rolling sequence number indicates a transmission sequence of the data packet. The sending node receives a packet loss feedback from the receiving node. The packet loss feedback is generated after the receiving node detects a packet loss event according to a rolling sequence number of a received data packet. The sending node determines a random sequence number of a lost data packet based on the received packet loss feedback. The sending node retransmits a data packet corresponding to the determined random sequence number. The retransmitted data packet carries a new rolling sequence number.
