The Tools Pillar enhances the testbed-native network monitoring service that supports experiments on PlanetLab Europe. It consists of two work packages:

• WP4 Topology Information - leader: Dr Timur Friedman, UPMC Paris Universitas
  Uses mostly active measurements to probe the network and furnish information about its structure to applications and researchers.
• WP5 Packet Tracking - leader: Dr Tanja Zseby, Fraunhofer Fokus
  Uses mostly passive measurements to give applications and researchers precise information regarding their packets as they pass through particular points in the network, thus allowing a better understanding of application performance.
