Given the era of the Information and Knowledge Society, Ecuador is implementing government policies focused on fulfilling this commitment. Telecommunications services and infrastructure in the country have grown focused on solving the growing demand for resources of campus network users that affects network performance. We present a solution proposal based on SDN after a study of traffic in university campus networks; QoS policies in conventional networks; defining QoS policies in SDN and conventional networks. The results evaluated in conventional and SDN scenarios are shown; based on latency, jitter, bandwidth, packet loss; innovating by introducing SDN networks in real scenarios. We applied The T-Student statistical method for data analysis.
