    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: A control method includes sending, by a controller, a created context-aware model to a context-aware engine. The context-aware model is used to define a preset control performed when target data meets a trigger condition and to instruct the context-aware engine to send indication information to the controller when the context-aware engine determines that the target data meets the trigger condition. The preset control is used to implement a context-aware function. The indication information is used to indicate that the target data meets the trigger condition. The method also includes receiving, by the controller, the indication information. The method further includes performing, by the controller, the preset control based on the indication information.

    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.
