Desarrollo e implementación de una arquitectura horizontalmente escalable
(2017) Domíngues, Matías Gabriel; Martínez Correa, Facundo Nahuel; Pérez Cuñarro, Javier; Álvarez-Hamelin, Ignacio
"El Proyecto TiX (Traffic Information eXchange) busca crear una herramienta para la medición de calidad y uso en las conexiones a Internet con la menor saturación posible del canal."
Extensión de TiX para medición de la calidad de los accesos Internet domiciliarios
(2015) Galindo, José Ignacio S.; Pereyra, Cristian Adrián; Álvarez-Hamelin, Ignacio
"El presente estudio se enfoca en investigar nuevos requerimientos, mejorar y agregar diversas funcionalidades del software, y finalmente en llevar a cabo pruebas con un número significativo de usuarios para analizar los resultados obtenidos mediante el uso del mismo."
Studying the evolution of content providers in IPv4 and IPv6 internet cores
(2019) Carisimo, Esteban; Selmo, Carlos; Álvarez-Hamelin, Ignacio; Dhamdhere, Amogh
"There is recent evidence that the core of the Internet, which was formerly dominated by large transit providers, has been reshaped after the transition to a multimedia-oriented network, first by general-purpose CDNs and now by private CDNs. In this work we use k-cores, an element of graph theory, to define which ASes compose the core of the Internet and to track the evolution of the core since 1999. Specifically, we investigate whether large players in the Internet content and CDN ecosystem belong to the core and, if so, since when. In addition, we examine differences between the IPv4 and IPv6 cores. We further investigate regional differences in the evolution of large content providers. Finally, we show that the core of the Internet has incorporated an increasing number of content ASes in recent years. To enable reproducibility of this work, we provide a website to allow interactive analysis of our datasets to detect, for example, ‘‘up and coming’’ ASes using customized queries."

TiX: medición de calidad de servicio de los proveedores de internet
(2014) Karpovsky, Alan Ezequiel; Loreti, Nicolás Daniel; Álvarez-Hamelin, Ignacio
"En esta propuesta se diseñará e implementará el software para un nuevo paradigma de medición activa, cuya utilización del servicio de Internet es solo el 1 % de la capacidad contratada. Además, permite el monitoreo las 24hs verificando la calidad del servicio otorgado por la empresa proveedora. Dicha herramienta implementará la metodología de medición y la presentación de resultados, tanto en el cliente (multiplataforma) como en el servidor (Linux)."
