This paper deals with important paradigms for the future post-IP generation: Knowledge and piloting planes, network virtualization and strong closed authentication. We describe these four paradigms and finally we can deduce what could be the future post-IP generation. We first introduce the architecture and a high security scheme that can be deduced from a strong closed authentication where the customers can get a perfect privacy. Then, we describe network virtualization that can provide a powerful way to run multiple networks, each customized to a specific purpose, at the same time over a shared substrate. Finally, we describe the meta control environment based on Autonomic Networking, associated with a knowledge plane and a piloting plane. This piloting system will be able to control the Quality of Service (QoS) in IP networks and consequently responds to users' requirements.
