Diseño e implementación de un entorno virtual de laboratorio para la realización de prácticas de redes LAN en el área de telecomunicaciones.

Abstract

This thesis addresses the challenge of the technological gap and the cost of creating physical data network laboratories in the faculty of technical education for development (FETD). The main objective was to design and implement a laboratory environment virtualized networking, which operates under the software-defined networking (SDN) paradigm, with the Mininet emulator and the Ryu controller in the OpenFlow 1.3 standard. This approach involved designing two fundamental topologies (Star and Hierarchical Tree) and use Python scripts to automate them, thus optimizing the deployment of a pilot workstation with intermediate hardware resources (Intel Core i5-5200U). Connectivity and performance testing with tools, including Iperf and Wireshark showed a transfer rate (order of Gbits/second) and a reactive processing latency of less than 1 ms: CPU usage was less than 60% so the system remained stable. Finally, the laboratory was assembled in OVF format (. OVA) that could be quickly used to deploy it to any location on campus. It is concluded that the proposed solution not only eliminates the needs of proprietary and expensive hardware, rather, it establishes a flexible and scalable pedagogical platform that adjusts to current trends in infrastructure as code (IaC) and reinforces the teaching-learning process in the telecommunications career.
