摘要： Embodiments of this application pertain to the field of broadband network technologies, and disclose a fault processing method, a control plane network element, a steering decision-making network element, and a related device. The method includes: In a process in which a terminal device accesses a network, if a control plane network element determines that a fault occurs on a steering decision-making network element, to ensure that the terminal device can continue to access the network, the control plane network element may directly control, without decision of the steering decision-making unit, the terminal device to send a data packet through a first user plane network element for a dial-up request. According to embodiments of this application, a best-effort path in a single-network-element fault scenario can be implemented, so that the terminal device can still normally dial up. In addition, in a migration process of the terminal device, if the fault occurs on the steering decision-making network element, message exchange between the control plane network element and the steering decision-making network fails. In this case, the control plane network element supports rollback of a delivered user entry, to prevent the terminal device from going offline.

摘要： 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, so that the USF device can identify a physical port of an SF device from which a user accesses. The USF device interacts with an SDN controller, to enable the SDN controller to deliver a configuration instruction to the corresponding SF device, so that the corresponding SF device configures a virtual local area network identifier of the first user equipment to a second sub-interface corresponding to a second UP device, so as to transfer user traffic to the second UP device. The first packet may be a DHCP packet or a PPPoE packet, and OPTION82/OPTION18 is added to carry the first location identifier

摘要： Embodiments of this application provide a broadband connection method and an apparatus. The method includes: A virtual broadband network gateway control plane vBNG-CP receives first indication information from a user plane selection function USF, where the first indication information indicates a second virtual broadband network gateway user plane vBNG-UP that replaces a firstvirtual broadband network gateway vBNG-UP when the first vBNG-UP is faulty. The vBNG-CP sends a user entry to the second vBNG-UP based on the first indication information, where the user entry is used by the second vBNG-UP to enable a user to access a network based on the user entry when the first vBNG-UP is faulty. According to embodiments of this application, when a user plane is faulty, broadband access of a user is not interrupted, and the user can continue to access a network.

摘要： This application provides a method for advertising a route, applied to a layer 3 network in an open systems interconnection OSI model. The network includes a control plane network element and a user plane network element that are connected to each other, and the method includes: receiving, by the user plane network element, a packet whose source IP address is a first IP address; determining, by the user plane network element, that the first IP address is not authenticated; sending, by the user plane network element, an authentication request that includes the first IP address to the control plane network element; receiving, by the user plane network element, a first session from the control plane network element; and advertising, by the user plane network element, first routing information based on the first session, where a destination address of the first routing information is the first IP address. The method can ensure that in the layer 3 network in the OSI model, when switching between a plurality of APs or routers connected to different BNGs, user equipment cannot maintain a network connected state.

摘要： This application discloses a method and an apparatus for accessing a gateway, and pertains to the field of communications technologies. In this application, an SLA level may be obtained based on user information of a terminal, and further a UP device corresponding to the terminal is determined based on the SLA level of the terminal. In this way, terminals with different SLA levels may be allocated to different UP devices for bearing, so that a specific terminal may access a specified UP device. This resolves a problem in a related technology that a terminal relatively randomly accesses a UP device. In addition, because an SLA level may be used to indicate a level of quality of service of a terminal, after terminals with different SLA levels access different UP devices, differentiated services may be provided on the different UP devices. Therefore, user requirements are met, and revenues are increased.

摘要： Embodiments of this application disclose a tunnel keepalive method, a network device, a system, and a storage medium, and pertain to the field of communications technologies. In the embodiments of this application, before a failure occurs in communication between a UP device and a CP device, the UP device receives tunnel information synchronized by the CP device. After a failure occurs in communication between the UP device and the CP device, the UP device performs tunnel keepalive based on the tunnel information, that is, the UP device maintains a tunnel between the UP device and a remote network device. In this way, tunnel teardown is not triggered because of the failure in communication between the CP device and the UP device. This solution can ensure that a network connection between a terminal and a remote end is not interrupted, that is, a user service is not affected.
