Abstract: This application provides a packet processing method and apparatus, a device, and a storage medium, and pertains to the field of communication technologies. In this application, a control identifier field is added to a packet, and the control identifier field indicates whether forwarding of the packet is allowed when the first network device does not configure the slice identifier on an outbound interface. The control identifier field and a slice identifier of a network slice are carried in the packet, so that the slice identifier and the control identifier field are transmitted on a network together. When a receive end does not configure the slice identifier on the outbound interface, the receive end can discard the packet based on the control identifier field, instead of forwarding the packet by using routing information.

Abstract: This application provides a packet processing method and a device. In this application, a control identifier field is added to a packet, and the control identifier field indicates whether forwarding of the packet is allowed when a resource corresponding to a slice identifier fails to be matched. The control identifier field and a slice identifier of a network slice are carried in the packet, so that the slice identifier and the control identifier field are transmitted on a network together. When a receive end fails to match the resource corresponding to the slice identifier, the receive end can discard the packet based on the control identifier field, instead of forwarding the packet by using routing information.

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 first network device receives location information sent by a second network device. The location information includes a location identifier used to identify a location of the second network device in a network and a plurality of associated flexible algorithms corresponding to the location identifier. The first network device generates, based on a first flexible algorithm of the plurality of associated flexible algorithms, first routing information to the second network device. The first flexible algorithm corresponds to a first network topology, the first network topology is a network topology in which the first network device is located, and the first routing information is used to send a packet to the second network device in the first network topology. One location identifier corresponds to a plurality of associated flexible algorithms, and routing information in different network topologies is generated based on different associated flexible algorithms.
