摘要： Embodiments of this application provide a method and an apparatus for obtaining a network slice identifier. In the method, a wireless access device receives a first service packet sent by a terminal; the wireless access device obtains a second service packet based on the first service packet, where the second service packet includes the first service packet and a network slice identifier; and the wireless access device sends the second service packet to a forwarding device.

摘要： This application provides a message processing method, a network device, and a controller, and pertains to the field of communication technologies. In this application, slice information, such as an identifier of a network slice and information about a path in the network slice, is carried in a message, and the message is reported to the controller, so that slice information on a forwarding plane is consistent with slice information on a control plane, and the controller controls a message forwarding path based on slice information on the network device. Therefore, this helps improve an effect of controlling the message forwarding path by the controller

摘要： A method for advertising a processing capability of a network device, a system, and a network device are disclosed, and relate to the field of communication technologies. The method is performed by a network device, and includes: generating a advertisement message including indication information, where the indication information is used to indicate a processing capability of the network device, the processing capability of the network device includes a processing capability of ignoring secondary path information included in a packet when the network device serves as a network device on a primary path for forwarding the packet and receives the packet including primary path information and the secondary path information, and the secondary path information is used to indicate one or more secondary paths for forwarding the packet when the primary path is unavailable. According to this method, when the primary path is used normally, the network device on the primary path for packet forwarding can ignore the secondary path information in the packet, to avoid a packet loss or incorrect forwarding caused because the secondary path information cannot be adaptively processed.

摘要： This application discloses a data transmission control method and apparatus, to resolve a problem of a waste of resources. In this application, one or more pieces of identification information are added, to determine an interface resource object, for forwarding a data packet, on an interface of a network device. The added one or more pieces of identification information include one piece of global identification information. The global identification information may correspond to a network slice, and different network slices correspond to different values of global identification information. A global network identifier corresponds to one or more interface resource objects. One interface resource object may be occupied by one network slice alone, or one interface resource object may be jointly shared by a plurality of network slices.

摘要： A packet forwarding method, a system, an apparatus, and a network device are provided, and pertain to the field of communications technologies. 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. According to this method, it can be ensured that the network device forwards service traffic by using a network resource allocated to the service traffic, so that quality of service for a service is improved.

摘要： Embodiments of this application disclose a packet transmission method and apparatus, and a network device. Specifically, 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.
