Abstract: 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.

Abstract: A round-trip time (RTT) evaluation system includes sending, by a first device, a plurality of packets to a second device on a path, where each of the packets carries a timestamp indicating a sending time of a corresponding packet, determining, by the second device based on a statistical value of one-way delays (OWDs) of the packets, timestamps carried in the packets, sending, by the second device, an acknowledgements (ACKs) to the first device, where the ACKs include the timestamps and ACK time information, and determining, by the first device, measurement values of an RTT of the path based on the timestamps, the ACK time information, and times when the ACKs are received.

Abstract: A data transmission method and apparatus, where a transmission end determines a redundancy time according to a delay requirement of a service, where the redundancy time indicates a time used for transmitting redundant data of native data of the service, and the redundancy time is less than or equal to a time indicated by the delay requirement. The transmission end determines a redundancy quantity N. The transmission end determines N redundancy transmission time intervals according to the redundancy time and the redundancy quantity. After the native data of the service is sent, in case of feedback data is not received within an nth redundancy transmission time interval, transmitting the redundant data of the native data for the nth time according to the nth redundancy transmission time interval.

Abstract: This application provide a retransmission control method, a communications interface, and an electronic device. When a transmit end transmits a first data packet to a receive end and does not receive an acknowledgement corresponding to the first data packet within a first RTO, the transmit end retransmits a second data packet based on a second RTO. The second data packet is a data packet transmitted by the transmit end after the transmit end transmits the first data packet. The second RTO is related to a receive timestamp of the acknowledgement corresponding to the first data packet and a transmit timestamp of the first data packet.
