Embodiments of the present invention provide a method and controller for announcing a bandwidth of a cluster system, where the method includes: obtaining, by the controller, at least two transmission paths between the first edge node and the second edge node; obtaining, by the controller according to bandwidths of the at least two transmission paths, a maximum bandwidth provided by the cluster system, where a bandwidth of each of the transmission paths is equal to a smallest bandwidth in bandwidths of all transmission links in the transmission path, and the maximum bandwidth is less than a sum of bandwidths of at least two transmission links connected to the first edge node; and announcing, by the controller, the maximum bandwidth to a node outside the cluster system by using the first edge node and/or the second edge node. According to the technical solutions provided in the embodiments of the present invention, accuracy of a maximum bandwidth that is announced by a cluster system to a node outside the cluster system can be improved. |
