Many service providers are implementing network functions virtualization (NFV) into their networks with the hope of achieving the promised benefits of the technology: dramatically reducing cost and increasing agility. However, if not managed properly, network complexity can quickly skyrocket.
In order to address NFV, service providers must approach their operations through the use of control loops at a per domain level. A classic example of this would be an autopilot system. This system works by continuously taking measurements and making adjustments to maintain a desired status to a specific sub-system of the plane such as bearing, thrust, altitude, etc.
By applying the same principles and abstracting what's happening in the network and enabling a domain to manage itself, service providers can ensure that their NFV implementation is successful.
