Abstract: 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.

Abstract: A route advertisement method, where a second communication apparatus sends a BGP message to a third communication apparatus. The BGP message includes a first routing prefix, a first next-hop address, and a first color attribute. An address segment of the first routing prefix is a first address segment of the second communication apparatus, and the first color attribute indicates a first service intent. The second communication apparatus may further advertise a first SRv6 service route to a first communication apparatus. The first SRv6 service route includes a first SRv6 SID which is an address in the first address segment. The second communication apparatus and the first communication apparatus belong to different domains.

Abstract: A message processing method includes slice information, such as an identifier of a network slice and information about a path in the network slice, that 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.

Abstract: In a data transmission control method, 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.
