Abstract: A method for accessing a gateway and an apparatus are disclosed, relate to the field of communication technologies, and are applied to a network system including a virtual broadband network gateway (vBNG), where the vBNG includes a control plane (CP) device and a plurality of user plane (UP) devices managed by the CP device, and the network system further includes a user plane steering function (USF) device. The method includes: The USF device obtains user information of a target terminal; the USF device determines a target UP device in the plurality of UP devices based on the user information and load of the plurality of UP devices; and the USF device indicates the target terminal to access the target UP device. Therefore, an appropriate UP device is selected for the target terminal in the network system including the vBNG, and load balancing between the plurality of UP devices is implemented.

Abstract: This application relates to methods, devices, and systems for generating a detection policy. An example method can be applied to a controller. In the example method, the controller obtains path information, where the path information includes information about a first network device, and the first network device belongs to a network device through which a packet passes from a source end to a destination end. The controller generates a detection policy for a second network device based on the path information and delivers the detection policy to the second network device, where the second network device is the same as or different from the first network device.

Abstract: 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.

Abstract: A controller receives an access request message of a to-be-served flow that is sent by a network device. 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.
