Comparación de una red convencional con una red definida por software (SDN)

Abstract

Although at the beginning the management of conventional networks could be covered with a small demand for administrators, its gradual growth has given rise to drawbacks such as the lack of flexibility concerning programmability and the management of its elements. Taking into account that networks defined by software or also known as Software Defined Networking (SDN) were born as a study knowledge model that focuses differently on the management and control of networks compared to the current operation of conventional networks. This article focuses on comparing a conventional network against an SDN network using GNS3 and Mininet software as emulation means, taking as comparison metrics: latency, packet loss, and throughput, for which a network scenario of tests with redundant links and multiple hosts. When analyzing the data produced by the different tests, it was possible to show a better performance of the software-defined network (SDN), since it presented an average delay of 82.32% less than the conventional network, thus determining the efficiency of the networks. SDN versus a conventional network.
