Abstract: The present disclosure discloses a flow specification (FlowSpec) message processing method. In the method, a controller forwards device interface information reported by the forwarding device; selects at least one forwarding device interface to which a FlowSpec rule needs to be applied from the received forwarding device interface information; generates an application interface rule based on the at least one forwarding device interface to which the FlowSpec rule needs to be applied; and sends a FlowSpec message to the forwarding device.

Abstract: Embodiments of this disclosure include a method where an access point (AP) device sends, to an access point controller (AC) device, a data tunnel support capability used to indicate a type of at least one data tunnel supported by the AP device. The type of the at least one data tunnel includes a virtual extensible local area network (VXLAN). The AP device receives configuration information of a VXLAN tunnel sent by the AC device. A local device of the VXLAN tunnel is the AP device, and the configuration information of the VXLAN tunnel includes an internet protocol (IP) address of at least one peer device of the VXLAN tunnel and virtual network index (VNI) information of the VXLAN tunnel. The AP device generates tunnel encapsulation information and routing information based on the IP address of the at least one peer device of the VXLAN tunnel and the VNI information.
