  • Publication number: 20240121174
    Abstract: The technology of this application relates to an information processing method, apparatus, and system. The method includes a controller determining network slice information corresponding to a first network device. The controller sends a border gateway protocol (BGP) packet to the first network device, where the BGP packet includes the network slice information, and the network slice information is used by the first network device to configure a network slice. According to the technical solution provided in this application, efficiency of delivering network slice information can be improved.

  • Publication number: 20240031299
    Abstract: A method and apparatus for ensuring a deterministic latency of a network slice, a storage medium, and a product, and belongs to the field of communication technologies. In this solution, topology information of different network slices can be associated with different gate scheduling periods, and the first device can determine a forwarding path of a service flow based on an SLA requirement and an association relationship between topology information and a gate scheduling period, so as to ensure a deterministic latency of the network slice. In addition, because different network slices can be associated with different gate scheduling periods, when the network slices are used to carry various service flows, different service flows may be scheduled and forwarded based on different gate scheduling periods, to meet latency jitter requirements of different services, and ensure deterministic latencies of various services.

  • Patent number: 11824779
    Abstract: Embodiments of this application disclose a traffic forwarding processing method and a device. The method includes: A first network device receives a first packet that is from a second network device and that includes a MAC address of a destination device and a color identifier of the MAC address. The first network device obtains an address of a third network device, where the destination device is multi-homed to the second network device and the third network device. The first network device determines a first forwarding policy based on the address of the third network device and the color identifier, and forwards, to the third network device according to the first forwarding policy, traffic destined for the MAC address.

  • Publication number: 20230208754
    Abstract: Embodiments of this application disclose a method and an apparatus for transmitting a virtual private network segment identifier (VPN SID), and a network device. An egress node sends a VPN SID corresponding to the egress node to each node in a network, and indicates to each node to store the VPN SID of the egress node. In this way, both an ingress node and each intermediate node can sense and store the VPN SID. When a VPN service needs to be provisioned, because each node stores the VPN SID of the egress node, it is possible for each node to associate the VPN SID with a forwarding entry of the VPN service to be provisioned in a forwarding table, to implement VPN route convergence. In addition, for a of a VPN corresponding to the VPN SID and that is sent by a user side, both the ingress node and the intermediate node can guide forwarding of the packet based on a locally stored VPN SID, to implement VPN service-level control.

  • Patent number: 11618294
    Abstract: An active-passive dual mode switchable vehicle suspension system is provided. The suspension system includes a filter, a hydraulic pump, a one-way valve, a power takeoff, a servo valve, a suspension cylinder, an overflow valve, an energy accumulator, a reversing valve, a first pressure sensor, a second pressure sensor, a controller, an oil tank and a displacement sensor. Further related is a switching method for the active-passive dual mode switchable vehicle suspension system. When the active and passive dual-mode switchable vehicle suspension system is switched between modes, an oil pressure in the rodless cavity of the suspension cylinder and an oil pressure in the energy accumulator are adjusted to be equal in advance, so that the stable switching of the active-passive suspension system can be realized, and the vibration of the vehicle body is eliminated when the existing active-passive suspension system is switched.
