Resolución de alias para el cálculo de topologías

Trabajo presentado a las VI Jornadas de Ingeniería Telemática, 17-19 de septiembre de 2007, Málaga (España)The network topology is a fundamental parameter for managers and researchers. The traditional methodology for discovering the topology of a network is based on the tool traceroute, used from several vantage points in different subnetworks. The result is a set of sink trees where the nodes are the discovered IP addresses from the routers. However, few tools have faced the problem of identifying the nodes in different sink trees as interfaces in the same router. This paper shows a new methodology for this problem of alias resolution. It has been used in the european research network using the ETOMIC platform. It shows that the traditional methodologies are not effective in today’s networking scenario but can be easily improved at least in a factor of 3 in the number of successes.Este trabajo ha sido financiado por el Proyecto Integrado Evergrow (contrato 001935) del Programa FP6/IST/FET de la Comisión Europea y parcialmente por los proyectos del Plan Nacional TEC2004-05622- C04-04 y TEC2004-06437-C05-03/TCM
