Implementación de un Prototipo de Red Definida por Software para el Hotspot-Espoch Mediante un Controlador Basado en Openflow

Abstract

This research allows to implement a prototype network using a software-defined based on an OpenFlow controller oriented to the wireless HOTSPOT network called direction of information technology and communication (DITC) in the Polytechnic School of Chimborazo. This research consists of comparing three controllers based on Python: POX, RYU and PYRETIC, we obtain the optimum using shared indicators: throughput, latency and lines of code. Later we built two prototypes: a prototype called CURRENT simulating HOTSPOT and another prototype called network solution using the driver which was more suitable. Both prototypes are compared for performance testing; they show whether the prototype SOLUTION improves HOTSPOT network. The prototypes are created and compared using a router and three laptops. To obtain the results iperf and wireshark were used which provide information about each prototype. Inductive method was applied to demonstrate if the SOLUTION prototype improves the situation in the HOTSPOT network through descrititive statistics which shows cualitative and cuantitative evaluation. The results of comparing the drivers are: POX with 87%, RYU with 80% and PYRETIC with 73%, in performance and latency. When comparing both prototypes we obtain: CURRENT prototype with 82.5% in throughput and SOLUTION prototype with 71.25% yield. It is concluded that POX is the most useful controller to create the SOLUTION prototype and a solution of a defined network by software is not suitable to implement wireless networks. It is recommended to the researchers to make a further study and to implement different drivers in programming languages.
