Which way to QoS in future networks: Distributed or centralized decision logic ?

The paper proposes the introduction of a Network Operating System, based on autonomic and cognitive capabilities, in order to improve manageability, QoS provision, and flexibility of future communication and processing infrastructures. The Network Operating System exploits a logically decentralized control logic through three planes: Network Control Plane, Resource Control Plane and Knowledge Plane. On one side the Network Operating System adopts the self-organization concepts towards the orchestration of virtualized resources hooked in “Network of Networks”; on the other side it interacts with a 0-Touch Management System, which is in charge of actuating lighter management functions which are still requesting human intervention. Paper concludes by elaborating about what a proper level of decentralization of control logic could be.
