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.

“Automation algorithms do not
care about surviving. We pilots do!
"Automation is not a choice, it's
a freakin' necessity” –Neil McRae,
MD and chief architect, BT.
Bill Gates, Microsoft: “Automation
applied to an inefficient operation
will magnify the inefficiency”

Solution: disaggregation of
network devices
• Faster innovation cycles with
software features
• Avoiding vendor lock-in
with open interfaces
• Choosing from best
software supplier
• Leverage standardized
hardware for cost and scale
Automated control only works with flexible and adaptable network
@*#!! - hardware limitations compromise agility
