    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.

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 user equipment to access a network. After receiving a request packet sent by a gateway control plane device, a control device obtains, by parsing the request packet, a home identifier corresponding to first user equipment. The control device determines, based on the home identifier, a corresponding first target gateway user plane device when the first user equipment goes online, so that a plurality of user equipments corresponding to a same home identifier all go online through the first target gateway user plane device. It can be learned that, in embodiments of this application, a plurality of sessions of a same home are managed based on a home identifier, so that different user equipments in a same home go online through a same gateway user plane device, thereby implementing unified rate limiting in the home.

    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.
