Abstract
El objetivo de nuestro proyecto es la creación de un controlador para usar de forma sencilla topologías virtuales de red y el estudio de las redes definidas por software. Para ello estudiamos el protocolo OpenFlow y su implementación más conocida Open vSwitch.
Para el desarrollo de nuestra aplicación elegimos el lenguaje Tcl-Tk debido a la facilidad para la creación de la interfaz gráfica y la simplicidad del lenguaje mediante script, para ello fue necesario el estudio de sus peculiaridades.
Nuestra aplicación es capaz de generar una topología de red y la gestión del flujo de datos de estos mediante la creación, eliminación y gestión de bridges virtuales, interfaces físicos, tuntap y enlaces vlink. Además de tener la capacidad de generar archivos para guardar y cargar los estados de la misma.
Por estas razones pensamos que el proyecto cumple las expectativas iniciales ya que hemos entendido desde la base el funcionamiento de las redes definidas por software y hemos podido desarrollar nuestra aplicación para la creación de nuestros entornos virtuales.

Our application is capable of generate a network topology, the management of data flow through the creation, elimination and management of virtual bridges, physical interfaces, tuntaps and Vlink links. Furthermore, having the capacity of generating files in order to save and load the states of itself. Because of that reasons, we consider the project meets the main expectations due the fact that we understood since the beginning the performance of the networks defined by software and we have been able to develop our application for the creation of our virtual environments.
