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: A network system includes a first network device, a second network device, and a third network device. The first network device is configured to: obtain a first route advertisement message, where the first route advertisement message includes a first route prefix; and obtain a second route prefix based on the first route prefix, where the second route prefix corresponds to a first network slice, and the second route prefix is a subnet prefix of the first route prefix. The first network device advertises a second route advertisement message to the second network device, where the second route advertisement message includes the second route prefix.

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.
