The network function virtualization (NFV) paradigm is an emerging technology that provides flexibility by allowing the allocation of functions over commodity hardware, like legacy servers in IT infrastructure. In comparison with traditional functions, implemented dedicated use NF
The advent of Network Function Virtualization (NFV) and Service Chains (SFCs) unleashes the power dynamic creation network services using Virtual Functions (VNFs). This is great interest to operators since poor service quality resource wastage can potentially hurt their revenue i
