Implementación de mejoras en la red inalámbrica basada en radioenlaces de la red RITA, para el despliegue y activación del laboratorio blockchain de la Universidad Distrital mediante el modelo ETOM

Abstract

This project addresses the modernization and optimization of the wireless communications network of the Advanced Technology Research Network (RITA) at the Universidad Distrital Francisco José de Caldas. The main objective was to implement improvements in the radio link infrastructure to enable the deployment and activation of a Blockchain technology laboratory, using the eTOM reference model to guide the project phases.

Initially, a comprehensive diagnosis of the state of the six main radio links was carried out, identifying performance issues, desynchronizations, and obsolescence in security protocols. Based on this analysis, maintenance and improvement actions were executed, including updating protocols to SNMPv3, optimizing antenna configurations, realigning a link affected by physical obstruction, and strategically migrating an inoperable link to the university's fiber optic network.

These improvements resulted in an increase of up to 50% in the throughput of key links and an overall stabilization of the network. Subsequently, a private three-node blockchain network based on Ethereum (Geth) was deployed on the optimized network infrastructure.

Finally, technical performance tests were conducted that validated both the robustness of the radio link network—with low latency and zero packet loss—and the functionality of the blockchain network, which operates stably with a constant block time of 15 seconds and efficient transaction processing. The project concludes successfully, providing the university with an improved network infrastructure and a functional blockchain laboratory for the benefit of research and academic training.
