SDN and NFV in 5G: Advancements and Challenges

The next generations of mobile networks have up the expectations and have prompted an entirely new technique in the networking future. This study gives optimal solutions that meet all the existing requirements enclose Software Defined Network (SDN) and Network Function Virtualization (NFV) in mobile networking. The major contribution of this research analysis is that it is a resource for literature reference for researchers and engineers because it gives and compares the most basic present solutions and consequently the future directions. In this paper, the main features of SDN & NFV are sum up as fundamental alternatives contributing to succeed the goals set by 5G. The essential needs and demanding situations faced through these solutions and consequently the most useful applications of the combination of SDN with NFV are defined. Finally, the main conclusions of this research and suggestions for possible future work in the field are described
