Arquitectura de red definida por software referencial para un proveedor de servicios de internet.

This work proposes a reference architecture for Software-Defined Networking aimed at an Internet Service Provider, with the purpose of improving scalability, automation, and operational efficiency compared to traditional architectures. A quantitative approach and a non-experimental design were adopted in a controlled environment, implementing a hierarchical topology (core–distribution–access) on Mininet and managed by the OpenDaylight controller (Carbon 0.6.4) using OpenFlow 1.3. Validation was carried out through functional tests: end-to-end connectivity (ping), throughput (iperf), and traffic capture (Wireshark), recording metrics such as latency, download/upload speeds, and resource consumption. The results show an average latency of 2.43 ms and speeds of 271 Mbps (download) and 214 Mbps (upload) in the SDN network, surpassing the values observed in two local operators referred to as ISP Quevedo 1 and ISP Quevedo 2 for the same indicators, which supports the technical feasibility of the proposal in representative ISP scenarios. The limitations of Mininet emulation and scalability considerations of the controller are also discussed, as well as the relevance of SDN/NFV for future extensions. Overall, the evidence suggests that the proposed SDN architecture constitutes a solid alternative for modernizing ISP networks, offering lower latency, higher performance, and centralized management with potential integration into IoT domains.
