| Abstract (English): | The massive deployment of services supported on the video streaming technology brings with itself the expansion of the data networks and the growth of the bandwidth necessary for carrying information. This demands greater control capabilities and network management that guarantees the quality of the service (QoS) for the final user. Such a demand has pushed the innovation of network architectures. Generating thus software-defined networks (SDN), network architecture paradigm where the data and control blueprints are uncoupled. This article analyzes the QoS metrics of a real and emulated SDN network for one of the video streaming services such as the television over the IP protocol (IPTV). The results show the possibility of equaling the QoS of a conventional architecture while offering other advantages for the network such as centralized logic and programmability at the management level.

| Abstract (Spanish): | El despliegue masivo de servicios soportados en la tecnología del video streaming, trae consigo la expansión de redes de datos y el crecimiento del ancho de banda necesario para transportar la información. Esto, a su vez, demanda mayores capacidades de control y gestión de red que permitan garantizar calidad de servicio (QoS) al usuario final. Tal demanda ha impulsado la innovación de las arquitecturas de red. Surgen así las redes definidas por software (SDN), paradigma de arquitectura de red donde se desacoplan los planos de datos y control. Este artículo analiza para uno de los servicios de video streaming, como lo es la televisión sobre el protocolo IP (IPTV), las métricas de QoS sobre una red SDN real y emulada. Los resultados demuestran que es posible igualar la QoS de una arquitectura convencional, ofreciendo otras ventajas a la red como la lógica centralizada y programabilidad desde el plano de gestión.
