Abstract: Embodiments of the present invention provide a route advertisement method, and controller, where the method is applied to a BGP-based routing network, a physical controller in the routing network is connected to multiple physical routers, and the method includes: receiving, by the physical controller, routing information reported by at least one physical router; obtaining a traffic path in which the at least one physical router is used as an egress router to transmit traffic to a destination router; generating a route for a physical router in the traffic path; and delivering the generated route to a corresponding physical router. In these embodiments, it is avoided that congestion occurs at an egress router, and a router that receives the traffic may generate a route for the router according to the traffic path so as to transmit the traffic to a next-hop router of the router without a need of recalculation.

Abstract: A network management method includes a control device that receives information indicating that a device goes online, where the information indicating that a device goes online includes position information of an online device. The control device determines, based on the position information of the online device, that the online device belongs to a first fabric plane of a network topology within a network range managed by the access control device, where the network topology is planned as at least one fabric plane, and a forwarding resource associated with the first fabric plane is isolated from a forwarding resource outside the first fabric plane. The control device determines, based on the first fabric plane, configuration information of the online device, and sends the configuration information to the online device, where the configuration information is used by the online device to perform automatic online configuration.
