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 method for creating a port group, includes generating, by a first software defined network (SDN) controller, the specified identifier according to a device identifier of a first forwarding device in a preset path, a device identifier of a last forwarding device in the preset path, and a device identifier of a specified forwarding device in the preset path; and sending, by the first SDN controller, the specified identifier to a second SDN controller, so that the second SDN controller creates, on the specified forwarding device, a specified port group corresponding to the specified identifier. Therefore, the first SDN controller needs to interact with the second SDN controller only once, to create a port group on the specified forwarding device that is directly controlled by the second SDN controller, and thus the port group creation process is simple.

Abstract: A SDN orchestration method includes: obtaining a first request for creating a first logical switch; creating a control plane instance of the first logical switch, and sending first configuration information to instruct the first forwarding device to configure the data plane instance of the first logical switch; obtaining a second request for connecting the first logical switch to a first logical router; sending second configuration information to instruct the first forwarding device to configure a first port of the data plane instance of the first logical switch to be communicatively connected to a second port of a data plane instance of the first logical router on the second forwarding device configured with the data plane instance of the first logical router; and sending third configuration information to instruct the second forwarding device to configure the second port to be communicatively connected to the first port.

Abstract: A service processing method is applied to a system including a first distributed node and at least two second distributed nodes to ensure correct service processing. The first distributed node communicates with a controller using the second distributed nodes. The service processing method performed by the first distributed node, includes obtaining a first operation request, where the first operation request includes a first service object, allocating a first identification code to the first operation request according to a preset rule, where the first identification code identifies a processing sequence of the first operation request for the first service object, and sending the first operation request and the first identification code to the controller using a second distributed node such that the controller determines, according to the preset rule and the first identification code, whether the first operation request needs to be processed.
