En este artículo se presenta la construcción de un modelo de tráfico para un servicio multimedia y su evaluación mediante técnicas de emulación. Se lleva a cabo la caracterización del tráfico para la obtención del modelo estadístico que describe el comportamiento del servicio y permite su simulación. Se describe el entorno de experimentación y los escenarios de evaluación, donde se inyecta tráfico real sobre una red virtual. Finalmente, los resultados muestran las previsiones a tener en cuenta de acuerdo con el consumo de recursos en el uso de este tipo de técnicas de emulación y el análisis del comportamiento del modelo.]]></p></abstract>
<abstract abstract-type="short" xml:lang="en"><p><![CDATA[Abstract With the increase of bandwidth in modern networks, there are progressively more and more services deployed on communication networks, so it becomes necessary to conduct studies about the behavior of the generated traffic and its impact on networks and other services. On this article we present the construction of a traffic model for a multimedia service and its evaluation using emulation techniques. The characterization of the traffic is executed for obtaining the statistic model that describes the performance of the service and allows its simulation. The environment of experimentation and the evaluation scenarios are described, where real traffic is injected on a virtual network. Finally, the results show the forecasts to consider in terms of resource consumption in the use of these kinds of emulation techniques and the analysis of the model performance.]]></p></abstract>
