Abstract: The application discloses a packet transmission method, an apparatus, and a network device. In an embodiment, a first network device obtains identification information corresponding to a service flow, and reserves a forwarding resource based on the identification information. The forwarding resource is used by the first network device to forward the service flow to a second network device. The first network device further sends a packet including the identification information to the second network device, and the second network device reserves a corresponding forwarding resource based on the identification information in the packet. Network devices perform resource reservation hop by hop by sending the packet including the identification information, and do not need to perform resource reservation based on a transmission path that is pre-calculated and planned, so that load of the network device or a controller is reduced, and resource reservation flexibility is improved.

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.

Abstract: A packet forwarding method, a system, an apparatus, and a network device are provided. The method is performed by a network device, and includes: obtaining first identification information of a first network resource required for forwarding first traffic to which a first packet belongs; determining a target port set based on the first identification information and a destination address of the first packet, where the target port set is associated with the first network resource; and selecting a first port from the target port set to forward the first packet.
