RIOS, Ramiro A.. Conceptualization of SDN and NFV. Maskay [online]. 2016, vol.6, n.1, pp.29-34. ISSN 1390-6712.

Due to the increasing demand of cloud computing services, along with the advent of the Internet of Things and the growing number of network connected devices, it becomes compulsory to explore different forthcoming solutions in order to have more flexible, easy-expandable technology platforms available and also capable of tolerating and supporting new and current services. Exploring these technological approaches must necessarily start off from theoretical foundations. Consequently, this document intent is to clarify the concepts of SDN and NVF, which are usually misinterpreted, among the readers. Three leading questions have been established in order to conceptualize these terms: What do SDN and NFV mean? Why are SDN and NFV necessary? What kind of advantages do SDN and NFV offer for data networking? The answers, based on selectively analyzing relevant documentation, will provide enough information to understand and distinguish the scopes of both terms. Additionally, clarifying these terms will aid in the effort to identify the features of a new network architecture, which might as well be implanted within mobile network operators. This new network architecture will be considered to face the technological challenges that resulted by the increasing demand of network services.

Keywords : NFV; SDN; virtualization.
