Abstract: Embodiments of this application disclose a network traffic migration method and apparatus. The network traffic migration method includes: obtaining a bandwidth usage parameter value of each of M vBNG-UP network elements, where M is an integer greater than 1; when a bandwidth usage parameter value of a first vBNG-UP network element reaches a first threshold, determining a second vBNG-UP network element based on the sum of bandwidths occupied by to-be-migrated network traffic of one or more terminal devices in a first device group on the first vBNG-UP network element and a bandwidth usage parameter value of one or more vBNG-UP network elements in a vBNG-UP network element group; and migrating the to-be-migrated network traffic of the terminal devices in the first device group to the second vBNG-UP network element.

Abstract: A communication method, a device, and a system are disclosed. An SF device adds a first location identifier including an identifier of the SF device and an identifier of a first physical port to a received first packet sent by first user equipment, and sends a second packet to which the first location identifier is added to a first UP device. The first UP device sends a third packet to a CP device, and the CP device sends the third packet to a USF device. The USF device interacts with an SDN controller, to enable the SDN controller to deliver a configuration instruction to the corresponding SF device. The first packet may be a DHCP packet or a PPPoE packet, and OPTION82/OPTION18 is added to carry the first location identifier.

Abstract: This application discloses a method for controlling subscriber access to a network, a device, and a system. A control plane device receives a first access request packet of a first subscriber, determines, based on a first correspondence, a first household to which the first subscriber belongs, then determines a first user plane device based on a second correspondence, and indicates the first subscriber to access the network through the first user plane device. The control plane device allocates, to a same user plane device, a subscriber who belongs to a same household and who accesses the network, so that the same user plane device provides a broadband network access service for the subscriber who belongs to the same household and who accesses the network.

Abstract: This application discloses a traffic sending method. The method includes: a control plane device obtains, based on a packet sent by a terminal, a first service function combination corresponding to the terminal, where the first service function combination includes at least one service function. The control plane device configures a first policy on a user plane device based on the first service function combination, the first policy indicates a first service chain, and the first service chain corresponds to the first service function combination. The control plane device sends first user entry information to the user plane device, where the first user entry information includes an identifier of the first policy and an identifier of the terminal, and the first user entry information indicates the user plane device to send traffic from the terminal to the first service chain based on the first policy.
