Abstract: The present invention provides a packet processing method and an apparatus. The method includes: determining a to-be-installed flow entry and packet sending information; and sending, to a switch, a flow entry installation message carrying the to-be-installed flow entry and the packet sending information, so that the switch obtains the to-be-installed flow entry and the packet sending information from the flow entry installation message, installs the flow entry, and sends a packet according to the packet sending information. In the present invention, a controller sends a flow entry installation message carrying a to-be-installed flow entry and a packet sending message, where the to-be-installed flow entry and a to-be-sent packet are simultaneously sent, so that a switch simultaneously receives the to-be-installed flow entry and the to-be-sent packet, and performs flow entry installation and packet sending, thereby reducing unnecessary signaling exchange, and improving efficiency of flow entry installation and packet sending.

Abstract: This application discloses a path processing method and apparatus, and a terminal. In the path processing method, user equipment may determine, based on connection parameter information corresponding to at least one existing packet data network (PDN) connection, whether a target PDN connection satisfying a target connection condition exists in the at least one existing PDN connection. When the target PDN connection satisfying the target connection condition exists, the user equipment may transmit a service packet by using the target PDN connection. When the target PDN connection satisfying the target connection condition does not exist, the user equipment may initiate establishment of the target PDN connection, to transmit a service packet by using the established target PDN connection. As can be learned, when transmitting the service packet, the user equipment may transmit the service packet by using the target PDN connection satisfying the target connection condition.

Abstract: Embodiments of the present disclosure provide a routing control method, network device, and controller. The method may include the network device obtaining a route suppression request. The method may also include determining the second routing entry. Furthermore, the method may include setting a state of the second routing entry to a non-delivery state that is used to indicate that the second routing entry does not need to be delivered to a forwarding table. In the method, the network device may have a first routing entry and a second routing entry, an address prefix of the first routing entry is a first address prefix, an address prefix of the second routing entry is a second address prefix, a network segment to which the second address prefix belongs is a subset of a network segment to which the first address prefix belongs, and a mask in the second address prefix is greater than a mask in the first address prefix.

Abstract: A data buffering method including: a session management function (SMF) interacting with a first user plane function (UPF1) and a second UPF2, such that the UPF1 sends first downlink data of a first session to an access network device via UPF2, where UPF1 is an anchor of the first session; and the SMS releasing UPF2 in a procedure in which a terminal device enters an idle state and a transmission resource associated with the first session in an access network is released, where UPF1 buffers incoming second downlink data of the first session. After the terminal device is switched to a connected state, both a transmission path of incoming third downlink data of the first session and that of the buffered second downlink data pass through UPF1, UPF3, the access network device, and the terminal device successively.
