Abstract: This application provides a subflow establishment method. A local-end device obtains an identifier of an operator currently accessed by a network interface card of the local end device. The local-end device obtains a plurality of IP addresses of a peer-end device and identifiers of operators to which the plurality of IP addresses are homed; and establishes, by matching a plurality of operators corresponding to the local-end device and the plurality of operators corresponding to the peer-end device, a subflow between an IP address pair homed to a same operator. In this way, the established subflow does not cross operators as far as possible. This reduces negative impact of cross-operator communication of some subflows on transmission performance of a multipath connection, thereby better leveraging an advantage of the multipath connection in transmission performance in

Abstract: A packet transmission method and an electronic device. In the packet transmission method, a response packet request field is set in a service packet, and a sending device can set a value of a response packet request field in a sent service packet. When the sending device needs a receiving device to send a response packet, the sending device changes a value of a response packet request field in a subsequently sent service packet, to trigger the receiving device to send the response packet to the sending device.

Abstract: This application discloses a communications method and related communications apparatus and system. The method includes recovering, by a first node, when detecting that a first packet is lost, the first packet according to a local recovery mechanism. The first packet is a packet obtained based on a packet sent by at least one first terminal to at least one second terminal, and the first node is a node on a network path between each first terminal and a second terminal communicating with the first terminal. The method further includes adding a first identification information related to local recovery, and sending the first packet. This application can reduce a transmission delay and improve transmission efficiency.

Abstract: A voice processing method is provided, including: when a terminal records a video, if a current video frame includes a face and a current audio frame includes a voice, determining a target face in the current video frame; obtaining a target distance between the target face and the terminal; determining a target gain based on the target distance, where a larger target distance indicates a larger target gain; separating a voice signal from a voice signal of the current audio frame; and performing enhancement processing on the voice signal based on the target gain, to obtain a target voice signal. This implements adaptive enhancement of a human voice signal during video recording.

Abstract: The present disclosure discloses a method for determining a Transmission Control Protocol (TCP) congestion window, and an apparatus. The communications method includes: receiving, by a network node, a data packet; obtaining a load level of a first output port used for sending the data packet by the network node; updating a load level in the data packet; and generating a network node data packet and sending the network node data packet to a TCP receive end. A TCP receiving end adds a load level to a to-be-returned acknowledgement (ACK) packet. A TCP transmitting end determines a new congestion window based on the load level of the ACK packet and a current congestion window.
