Future 5G networks will exploit the inherent flexibility associated to the introduction of Network Function Virtualization (NFV) technologies in both the core network and even the Radio Access Network (RAN) through the software implementation of network functions running on general purpose computing/storage resources. The advent of the NFV paradigm provides an inherent capability to add new functionalities, extend, upgrade or evolve existing functionalities and to customize the network on a per-tenant basis. In this context, this work intends to make an analysis of the cuFuture 5G networks open a new spectrum of possibilities, both at the level of services it can offer, and at the level of its deployment. This thesis aims to make a study of some of the technologies that make possible the arrival of 5G, such as virtualization and virtualization applied to networks, NFV. In order to better understand the defined standard for NFV, the analysis of market NFV-MANO available tools is included. In addition, the study and evaluation of the deployment process of a virtualized 5G network scenario has been performed with HPE NFV Director
