摘要： Embodiments of this application provide a communication method and a related device. In the method, a control plane entity CP sends a first message to a user plane steering function entity USF. The first message includes end user information, and indicates the USF to schedule an end user based on the end user information. Then, the CP determines, based on an identifier of a target UP carried in a first request message sent by the USF, to schedule the end user to the target UP. In other words, a scheduling policy of the end user is determined via the USF. Then, the CP further processes a connection between the end user and the target UP based on the identifier of the target UP, so that the scheduling policy of the end user is determined in a BNG device via the USF. This reduces processing load of the control plane entity CP, and improves communication performance.

摘要： This application discloses a user keepalive method and apparatus, and relates to the communications field. The method provides a solution to keep a user alive in a CU-separated broadband access gateway. The method is used in a broadband access gateway including a control plane entity and a user plane entity. The broadband access gateway is configured to enable a user to access a network. The method is performed by the user plane entity. The method includes: sending probe packets to the user based on a preset parameter obtained by the user plane entity in advance; and if a probe response packet sent by the user is not received in preset duration, sending a probe failure message to the control plane entity, where the probe packets are used to check whether a communication link between the user and the user plane entity is faulty, and the probe failure message indicates the control plane entity to perform offline processing on the user.

摘要： This application provides a packet transmission method, apparatus, and system, and relates to the field of network technologies, to improve utilization of a user-side link and reduce load on the user-side link. The method is applied to a network architecture including a user terminal, a first forwarding device and a second forwarding device. A tunnel is disposed between the first forwarding device and the second forwarding device. Packets of the user terminal are forwarded to the first forwarding device and the second forwarding device in a load balancing mode. The method includes: The first forwarding device receives packets forwarded by the user terminal in the load balancing mode, where the packets include a keepalive packet, and the first forwarding device is a standby forwarding device corresponding to the user terminal. The first forwarding device forwards the keepalive packet to the second forwarding device through the tunnel, where the second forwarding device is an active forwarding device corresponding to the user terminal.

摘要： This application provides a network service management method, apparatus, and system. A controller receives an access request message that is of a to-be-served flow and that is sent by a network device, where the access request message includes an identifier of the to-be-served flow and an identifier of a terminal that sends the to-be-served flow. The controller determines service level information of the to-be-served flow based on the identifier of the terminal and the identifier of the to-be-served flow. The controller determines a transmission path of the to-be-served flow and a transmission path of a being-served flow based on the service level information of the to-be-served flow and service level information of the being-served flow. The controller publishes the transmission path of the to-be-served flow and the transmission path of the being-served flow to the network device. In the embodiments of this application, the controller simultaneously determines paths of the to-be-served flow and the being-served flow based on content of a plurality of aspects, and dynamically adjusts the to-be-served flow and the being-served flow based on a flow type, so that more SD-WAN users meet an optimal solution of a service level agreement signed between the SD-WAN users and an SD-WAN service provider.

摘要： 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. In this way, unified management may be performed through one user plane device on a plurality of subscribers who belong to a same household and who access the network, a process of managing the plurality of subscribers who belong to the same household and who access the network may be simplified, and efficiency of managing the plurality of subscribers who belong to the same household and who access the network may be improved.

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.
