Abstract (es_ES)

El costo en infraestructura y acceso a tecnologías emergentes en redes de telecomunicaciones, hizo necesario disponer de un planteamiento de evaluación de Calidad de Servicio utilizando mecanismos de encolamiento basado en simulación. El objetivo en este artículo fue evaluar diferentes técnicas de encolamiento modeladas bajo diversos escenarios de campus de redes backbone, para comparar su desempeño usando la herramienta de simulación OPNET. La evaluación apuntó hacia la medición de variables claves en el desempeño de la red como retraso, pérdida de paquetes y variación del retraso (jitter), entre otras. Son presentados aquí los resultados obtenidos en la utilización de éstos mecanismos al momento de otorgar diferenciación a tráficos sensibles a factores de congestión presentes en las redes IP, tales como tráfico en tiempo real; obteniendo un significativo mejoramiento en el desempeño de la red.

Abstract (en_US)

The cost in infraestructure and access to emerging technologies on telecommunications networks, made necessary to have a mechanisms the quality of service assessment using queuening based. Objective in this article was evaluate different technical modeled various scenes of campus backbone network, in order to compare his performance using the tool of simulation OPNET. The evaluation aimed to the measurement of keys variables in the performance networks like delay, packet loss and jitter, among others. Are show here the results once these were gotten from utilization mechanism when granting differentiation to sensitive traffics to present factors of congestion in IP networks, such like traffic in real time; collecting a significant improvement in the network performance.
