Abstract: This application provides a data distribution method includes: A network device buffers first data, where the first data is data of a service that is provided by a server for a first terminal device; the network device receives N first data requests sent by N second terminal devices; and when data requested by the N first data requests is data provided by the server based on the service, the network device intercepts the N first data requests and sends the buffered first data to the N second terminal devices. This can reduce a plurality of connections that are used to transmit data of a same service and that exist on a channel between the server and the network device, thereby occupying a smaller downlink bandwidth to transmit the data of the same service from the server to the network device.

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 hybrid access gateway receives packets that are sent by a network side device and are destined for a home gateway. When detecting that congestion occurs on a first transmission link and that no congestion occurs on a second transmission link, the hybrid access gateway obtains a first committed information rate (CIR) of the first transmission link and a second CIR of the second transmission link, classifies the packets into a first-type packet and a second-type packet, and transmits the first-type packet using the first transmission link and the second-type packet using the second transmission link. By properly allocating packets transmitted on the second transmission link, the hybrid access gateway can control one-way delays of the first transmission link and the second transmission link, thereby avoiding a packet loss caused by a sequencing buffer overflow.

Abstract: 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.
