The Network Functions Virtualization (NFV) enables the emulation of Virtual Network Functions (VNFs) through SW configured over physical and sharable resources of generic HW, referred as COTS (Commercial off-the-shelf). Therefore, NFV replaces the traditional concept of network services implemented on dedicated HW and came to allow not only significant reductions in equipments acquisition (CAPEX) and operational costs (OPEX), but also to enable a bigger agility and speed in the development and management of network services composed by VNFs.
