Etomic advanced network monitoring system for future internet experimentation

Abstract. ETOMIC is a network traffic measurement platform with high precision GPS-synchronized monitoring nodes. The infrastructure is publicly available to the network research community, supporting ad-vanced experimental techniques by providing high precision hardware equipments and a Central Management System. Researchers can de-ploy their own active measurement codes to perform experiments on the public Internet. Recently, the functionalities of the original system were significantly extended and new generation measurement nodes were deployed. The system now also includes well structured data reposito-ries to archive and share raw and evaluated data. These features make ETOMIC as one of the experimental facilities that support the design, development and validation of novel experimental techniques for the fu-ture Internet. In this paper we focus on the improved capabilities of the management system, the recent extensions of the node architecture and the accompanying database solutions. Key words: ETOMIC, network measurement infrastructure, active measurements
