Published on

Network management systems are undergoing a transformation into semi-automated eventually autonomous control systems. In his presentation at MPLS+SDN+NFV World Congress 2019, Ulrich Kohn outlined the early stages of this shift. He put progress with SDN and AI into the context of multi-vendor networking and explained the crucial role of open interfaces as well as the need to balance continuity with the desire for automated, semi-autonomous control.
