Abstract: Nowadays, satellite networks are a solution for rural and remote Internet connection where traditional terrestrial Internet urban access is not deployed, mainly, because of its cost. In this article we present results from the observation, analysis and characterization of transport traffic in a British Telecom’s VSAT Network (BT Latam). We have stressed our study on the Performance Enhancing Proxy for transport traffic, which improves performance when downloading information to VSAT’s terminals. This article represents the first of a series of unprecedented studies in Venezuela, and to the best of our knowledge, in Latin America.

Keywords: Satellite networks, VSAT, TCP, traffic profiling.

Resumen: Las redes satelitales se han convertido en una solución para la conectividad de sitios remotos donde la conexión terrestre no llega o es muy costosa llevarla a través de los medios masificados. En este artículo se presentan los primeros resultados de la observación, análisis y caracterización del tráfico transporte de la red VSAT propiedad de la empresa British Telecom Latinoamérica (BT Latam) en Venezuela. Hicimos especial énfasis en el Acelerador TCP el cual incrementa, considerablemente para el tráfico de datos hacia la VSAT, el rendimiento de las transferencias TCP. Este artículo corresponde al primero de un estudio inédito en el país y, en nuestro mejor esfuerzo de búsqueda, en Latinoamérica.

Palabras clave: Red Satelital, Red VSAT, TCP, perfil de tráfico.
