Abstract
A method for controlling a software-defined network “SDN” includes receiving (301) information provided by one or more external sources outside the software-defined network, generating (303) configuration data for changing configuration of one or more network elements of the software-defined network on the basis of the received information in response to a situation (302) where the received information indicates an occurred or forthcoming change of one or more operating conditions of the software-defined network, and sending (304) the configuration data to the network elements so as to adapt the software-defined network to changes of the one or more operating conditions. Therefore, the configuration capabilities provided by the software-defined networking are utilized for dynamically optimizing the software-defined network with respect to changes that are not necessarily indicated by information gathered inside the software-defined network but by information provided by the external sources outside the software-defined network.
