AMAYA FARINO, Luis Miguel et al. SDN Software Defined Networks using MiniNet. RCTU [online]. 2022, vol.9, n.1, pp.48-56. ISSN 1390-7697.  https://doi.org/10.26423/rctu.v9i1.489.

In the digital times where almost everything is connected and available from anywhere, traditional IP networks are still complicated and tedious to manage. There is difficulty in configuring the network according to predefined procedures and responding to load changes and failures through network reconfiguration. They are vertically integrated to make things much more complicated: the control and data planes are grouped together, which is why telecommunications companies have created the evolution in data communication, known as SDN or software-driven networks where the classic three-layer hierarchical model of the OSI model is not necessary. The objective of this paper was to present the SDN model and its characteristics, a small practice is shown deploying a virtual network using Virtual Box of four virtual machines, a MiniNet network emulator and with a Python script for the MiniNet in the communication rules. It could be observed that the administration of the SDN is easy and simple through a programming language, the definition of rules goes directly between machines and not through the network routes.
