    Abstract: Embodiments of this application provide a data stream transmission method. The method includes a sending device that dynamically determines a packet-loss-concealment policy based on first path status information of a path used to send a data stream. The sending device generates a packet-loss-concealment packet for the data stream according to the packet-loss-concealment policy. The sending device sends the data stream on the path. The data stream includes an original packet and the packet-loss-concealment packet. Therefore, when receiving the data stream, a receiving device decodes the data stream according to the packet-loss-concealment policy received from the sending device, and recovers, by using the packet-loss-concealment packet, an original packet lost in a transmission process. This effectively improves a packet loss recovery effect, and improves user experience.

    Abstract: A media stream sending method provides a live media stream for a client that enters a live broadcast room. A proxy server receives, from a first client, a first live broadcast room request message for requesting to enter the live broadcast room; the proxy server determines a role of the first client based on the first live broadcast room request message; and if the role of the first client is a slave user, the proxy server sends a first live media stream cached in the proxy server to the first client, where the first live media stream is a media stream that is sent by a media server to a second client through the proxy server, and a role of the second client is a master user.

    Abstract: 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.
