A method of providing a service (230) to a requesting Infrastructure Element (105, 110, 115; 245ie) belonging to plurality of Infrastructure Elements (105, 110, 115; 245ie) interconnected to form a data network (100) is proposed. The method comprises operating a computing system (120) for receiving a service request (220r) requesting the provisioning of a service (230) from the requesting Infrastructure Element (105, 110, 15; 245ie), the service request comprising an indication of one or more performance requirements; converting said service request (220r) in a service graph (230g), the service graph (230g) comprising at least one task (530) to be accomplished complying with said one or more performance requirements in order to provide said service (230); selecting at least one Infrastructure Element (105, 110, 115; 245ie) currently capable the accomplishment of said at least one task (530) complying with said one or more performance requirements; configuring the selected at least one Infrastructure Element (105, 110, 115; 245ie) for accomplishing said at least task (530), and causing the selected at least one Infrastructure Element (105, 110, 15; 245ie) to accomplish said at least one task (530) to provide the service (230) to the requesting Infrastructure Element (105, 110, 115; 245ie). |
