Abstract: A multicast data transmission method includes: determining, by a first BFIR in a first BIER domain, a BIFT-id and a bitstring that correspond to multicast data in a second BIER domain, where the BIFT-id is determined based on at least an SI to which a BFR-id of a first BFER belongs and a BSL supported by the first BFER, and the first BFER is a BFER in the second BFER domain that is used to receive the multicast data; encapsulating the multicast data into a BIER data packet, where a BIER header of the BIER data packet includes the BIFT-id and the bitstring that correspond to the multicast data in the second BIER domain; and finally sending the labeled BIER data packet to a second BFIR, where the label is a label corresponding to a prefix of the second BFIR.

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 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, a device, and a system for transmitting a multicast packet are provided. The method includes: when a device that is in a source subnet and that is connected to a core network receives a multicast packet of a target multicast group, determining addresses of devices that are in a plurality of destination subnets corresponding to the target multicast group and that are connected to the core network, replicating the multicast packet, to obtain a plurality of multicast packets whose quantity is equal to a quantity of the plurality of destination subnets, separately adding outer encapsulation to each multicast packet, and forwarding the multicast packet to which the outer encapsulation is added, where a destination address in the outer encapsulation is an address of a device that is in each destination subnet and that is connected to the core network.

Abstract: This application discloses a network congestion control method and a network device, and relates to the field of communication technologies, to improve continuity and completion of a packet in a transmission process of a Transmission Control Protocol (TCP) flow. In this application, when pre-congestion (that is, congestion may occur) occurs in a forwarding direction of the TCP flow, a forwarding device reduces a value of a receive window (RWND) field in an acknowledge (ACK) packet, to reduce a sending rate of a transmit end for a packet in the TCP flow or delay sending of a packet by a transmit end. This relieves buffer pressure of the forwarding device, reduces a packet loss, and improves the continuity and the completion of the packet in the transmission process of the TCP flow.

Abstract: The present disclosure relates to methods and devices for obtaining path information of a data packet. One example method includes receiving, by a network device, a data packet transmitted in a network, and obtaining, by the network device, path information of the data packet from a source end to a destination end, where the path information is a total hop count of routers passed through by the data packet from the source end to the destination end or a latency of the data packet from the source end to the destination end.
