A method for determining quality of service (QoS) includes receiving a first Internet Protocol (IP) packet, where the first IP packet includes a User Datagram Protocol (UDP) packet and a first IP header, determining, based on information in the first IP packet, a target QoS level to which the UDP packet belongs, dividing the UDP packet into at least two segments, encapsulating each of the at least two segments into a Multipath Transmission Control Protocol (MPTCP) packet, encapsulating the MPTCP packet into a second IP packet, where a payload length of a target IP packet in the second IP packet is equal to a byte length corresponding to the target QoS level, and sending the second IP packet to a peer device using an MPTCP connection with the peer device such that the peer device determines the target QoS level based on the payload length of the target IP packet.

Method and apparatus for determining quality of service, and storage medium

A packet transmission method includes: receiving packets on a plurality of subflow connections of a multipath transmission control protocol (MPTCP) connection, and determining, based on the received packets, that packets at an MPTCP layer are out of order; determining that a blocking packet causing out-of-order is not received within a tolerance time, where the tolerance time is less than a largest RTO in RTOs of the plurality of subflow connections; and sending, by the network component, a retransmission instruction packet of the blocking packet on a target subflow connection in the plurality of subflow connections, where the retransmission instruction packet is used to instruct a sending device of the blocking packet to retransmit the blocking packet. Thus, there is no need to trigger retransmission after a subflow RTO expires, thereby shortening a delay.
