This work package provides passive measurement technologies within the PlanetLab Europe testbed. Passive measurements are required to track packets and flows originated by experimenters. This is necessary to analyse various parameters like traffic volume at different nodes, packet transmission quality, paths that packets take through the network, etc. These parameters are needed for the evaluation and interpretation of experiment results. Passive measurements also provide input to capture the traffic conditions on the network during the experiments.

The development is based on the CoMo system developed within OneLab. It enhances the architecture by resource management functions and functions to perform synchronised multipoint measurements. Furthermore, it integrates data selection techniques and enhanced IPFIX features (IPFIX configuration, IPFIX file) that are currently standardised within the IETF with strong participation of the WP leader Fraunhofer.

The Objectives of this work package are:

• Provide a flexible (re-)configurable passive measurement infrastructure for PlanetLab Europe to support experiments by passive traffic monitoring
• Provide a resource management scheme
• Provide data selection techniques to control processing load and result data volume
• Provide methods for synchronised passive multipoint measurements
• Deploy standardised solutions and contribute to standardisation

• D5.1 Packet tracking architecture
• D5.2 Extended packet tracking capabilities
• D5.3 Status of the packet tracking infrastructure: operation, usage, validation and capabilities
