Resumen
La calidad de servicio (QoS) se define como la capacidad que tiene una red para administrar la demanda de tráfico según la clase de servicio, con el fin de satisfacer las expectativas del usuario y de acuerdo con unas métricas claramente establecidas, lo que aplica inclusive para las redes con tecnología PLC. Ante la necesidad de optimizar QoS en redes IP se plantea un diseño experimental de tipo factorial mixto, con el fin de evaluar el rendimiento de una red PLC para la transmisión de voz sobre IP, en términos del throughput, latencia y jitter, en un entorno residencial y con el uso de adaptadores PLC soportados en el estándar HomePlug AV. El resultado del experimento no solo establece el grado de influencia desde el punto de vista estadístico que puede presentar el tipo de codec utilizado o el número de estaciones activas, sino que permite identificar cuáles son los codecs más recomendados para transmitir voz sobre IP, mejorando el rendimiento de la red y garantizando adecuados niveles de QoS.

Faced with the need to optimize QoS in IP networks, a experimental design type mixed factorial is presented to evaluate the performance of a PLC network to the Voice over IP transmission, in terms of throughput, latency and jitter, in a residential environment and with the use of PLC adapters supported in the HomePlug AV standard. The result of the experiment not only establishes the degree of influence from the statistical point of view that you can produce the type of codec used or the number of active stations, but that allows you to identify which are the most recommended codecs to transmit voice over IP, improving the performance of the network and ensuring adequate levels of QoS.
