Some studies are tackling the integration of Network Function Virtualization (NFV) and
Software-Defined Networking (SDN) in different environments (eg, Cloud Computing and
Wide Area Network). The use of NFV technology, along with SDN, will play a significant role
in 5G networks, since they allow the network programmability and the fast delivery of new
services. Although NFV/SDN architectures have clear potential benefits, they are still at an
early stage of development. One of the main challenges is the definition of high-level …
