This document presents the development of a software-defined network (SDN) prototype using open-standard resources to enhance network management. The prototype, based on OpenFlow controllers, integrates with any network infrastructure to optimize capacity and efficiency. By applying Agile XP methodologies, real-time adjustments and improvements were made to meet emerging needs. The SDN prototype monitors information traffic according to policies set by the network administrator, achieving satisfactory results in initial tests of routing, monitoring, and packet reduction, ensuring uninterrupted data flow. Using the OpenFlow protocol and Floodlight controller, the prototype transforms network infrastructure into a programmable, agile, and scalable platform with centralized management, simulated via Mininet. This allows administrators to optimize resources, simplify network design, and increase flexibility, security, and efficiency. A key differentiation from traditional solutions is the prototype’s automation and centralized management, reducing manual configuration and enabling dynamic adjustments. This cuts implementation time for new services and improves network security and flexibility. Additionally, its vendor independence makes it adaptable to different infrastructures, facilitating integration with existing technologies without proprietary constraints. Initial tests showed reduced server load, enhancing both performance and energy efficiency, leading to significant operational cost savings. The system is scalable, supporting deployment in a wide range of network environments. In conclusion, this SDN prototype offers a flexible, scalable, and cost-effective solution, advancing network management. Future work could explore integrating AI to further automate network operations in high-demand environments.
