With the birth of Software Defined Networks (SDN) a new impulse was given to networks innovation, making it possible to decouple data plane and control plane. Several technologies were born with the aim of speeding up the implementation of new features, exclusive task of hardware manifacturers for years. One of them is P4, a technology capable of enabling the general-purpose programming paradigm in the networking world, thus telling the devices what exactly to do with incoming packets. Thanks to this new technology (2016), this thesis aims at proposing a new concept of SDN that breaks the main pillar of having one logical centralized control plane.
