Abstract: Embodiments of the present disclosure provide a failure protection method based on a ring protection link, a device, and a system, and nodes in the ring protection link include a forwarding device in an SDN. The method includes: receiving, by a network controller, a high-priority failure message sent by a first node, where the failure message includes information used to indicate a failure; obtaining, according to the failure message, data information about port state changes that are of the nodes and that are caused by the failure; and sending a high-priority switching message to each of the nodes, so that each of the nodes updates a local MAC address table according to the switching message, where the switching message includes the data information about port state changes that are of the nodes and that are caused by the failure.

Abstract: This application discloses a packet processing method and a related apparatus, applied to a network slice. The method includes: A first network device obtains a first packet, where the first packet includes a first slice identifier, the first slice identifier includes a plurality of consecutive sub-identifiers, the plurality of sub-identifiers indicate different attributes of a first network slice, and the first slice identifier identifies the first network slice to which the first packet belongs. The first network device forwards the first packet based on the first slice identifier. In this solution, a slice identifier including a plurality of sub-identifiers is carried in a packet. Different sub-identifiers indicate different attributes of a network slice.

Abstract: A network management method. The method includes: obtaining a network type of a target network; obtaining a logical network model of the target network based on the network type and a logical network recommendation model; determining a physical network model of the target network based on the logical network model and a physical network recommendation model; and performing network configuration based on the physical network model of the target network. An advantage of the embodiments lies in that, when a user inputs the network type of the target network instead of a large quantity of detailed network configurations, a network management system can automatically establish the required target network for the user, thereby greatly improving efficiency of establishing the target network.
