One of the main characteristics of the digital revolution is the acceleration of change. The technologies that have fueled the digital revolution over the past decades are experiencing increasingly rapid innovation cycles.To date, a significant increase in the number of users, devices, applications and traffic has presented new challenges to service providers. The SDN paradigm emerged to address some of these emerging challenges. SDN simplifies network management and allows automated network configuration on demand with optimal use of network resources.The work is devoted to the study of modern networks and the identification of opportunities for the implementation of virtualization of network functions in the context of SDN and NFV concepts. Because these are two new technological trends that are transforming network management. Together, they simplify the provisioning of network resources and provide greater network flexibility. This approach creates dynamic, flexible and scalable networks that use the virtualized infrastructure of modern data centers.
