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 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: A load balancing system, method, and apparatus, where the method includes: receiving, by a load balancing device, a first message from a client that is used to request to establish a first Transmission Control Protocol (TCP) connection; sending the first message to a server; receiving a second message from the client that is used to request to establish a second TCP connection; and determining, based on a token of the server included in the second message, that a destination device of the second message is the server, and sending the second message to the server, in order to establish the second TCP connection between the client and the server.

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 method and an apparatus for sending a TCP data packet and a system. The method includes: obtaining a first round-trip time of sending a TCP data packet in a network, and determining a second round-trip time; if the first round-trip time is longer than the second round-trip time, using a congestion window determined according to a first algorithm as a first congestion window; otherwise, using a congestion window determined according to a second algorithm as the first congestion window; and sending the TCP data packet by using the first congestion window. In the technical solution disclosed in the present invention, a current congestion window that exists when a first round-trip time is obtained grows to a first congestion window at one go, so that a requirement of a service for a throughput can be better met, and a network bandwidth can be utilized more effectively.

Abstract: A traffic distribution method and apparatus in a hybrid access network, where the method includes transmitting, by a hybrid access aggregation point (HAAP), probe traffic using a second tunnel after determining that a first tunnel is congested when user traffic is transmitted over the first tunnel, obtaining, by the HAAP, a status of the first tunnel and a status of the second tunnel, determining, by the HAAP according to the status of the first tunnel and the status of the second tunnel, whether the status of the first tunnel and the status of the second tunnel meet an offloading condition, and transmitting, by the HAAP, the user traffic using the first tunnel and the second tunnel after determining that the status of the first tunnel and the status of the second tunnel meet the offloading condition.
