  2. History • The European Traffic Observatory Measurement InfrastruCture (etomic) was created in 2004-05 within the Evergrow Integrated Project. • Since 2005 it is also part of a national programme Center for Comm. Net. Data Analysis ( ~ 3 M€) • Its goals: • to provide open access, public testbed for researchers experimenting the Internet • to serve as a Virtual Observatory active measurement data on the European part of the Internet Best Testbed Award ETOMIC the European Internet experimentation infrastructure www.etomic.org

  3. Founders • Built by the Center for Communication Network Data Analysis (CNDA). • Central management system by Navarra University, Spain • The measurement stations are hosted by European Universities in the Evergrow project, EuroLab members, MoMe members, associate partners of CNDA ETOMIC the European Internet experimentation infrastructure www.etomic.org

  4. Experimental sites

  5. Eurolabs Collaboration • an etomic station is hosted in the Eurolabs laboratory in Brussels • the etomic station arrived at Université Libre de Bruxelles in the summer of 2005 • reached the fully operational state in the autumn of 2005 ETOMIC the European Internet experimentation infrastructure www.etomic.org

  6. Eurolabs Collaboration ETOMIC the European Internet experimentation infrastructure www.etomic.org

  7. Eurolabs Collaboration ETOMIC the European Internet experimentation infrastructure www.etomic.org

  8. Hardware architecture • Each station consists of: • Server PCarchitecture • DAG 3.6 GE card with packet sending capability (Endace) • own GPS antenna (Garmin) for time synchronization • Repository and data processing: • Everlab IBM blade center (112 blades) ETOMIC the European Internet experimentation infrastructure www.etomic.org

  9. The GEANT connection ETOMIC the European Internet experimentation infrastructure www.etomic.org

  10. CMS ETOMIC the European Internet experimentation infrastructure www.etomic.org

  11. Web interface • Available via www.etomic.org • Account application -> own experiment design • Free access/sharing of measurement data • Experiment time slot reservation for registered users • Programming DAG card via the user friendly Application Programming Interface • Experiments are distributed automatically to the stations ETOMIC the European Internet experimentation infrastructure www.etomic.org

  12. What kinds of services I can get? Launch an experimentstep by step

  13. Experimental bundle ETOMIC the European Internet experimentation infrastructure www.etomic.org

  14. Scheduling Time slot reservation in a calendar system for the experiments Experiments ETOMIC the European Internet experimentation infrastructure www.etomic.org

  15. User experiments ETOMIC the European Internet experimentation infrastructure www.etomic.org

  16. Open repository ETOMIC the European Internet experimentation infrastructure www.etomic.org

  17. Database interface and schema In collaboration with astrophysics Virtual Observatory efforts Uploaded 2.5 billion measurements ETOMIC the European Internet experimentation infrastructure www.etomic.org

  18. You can get all the key environment information during your experiment Basic experiments

  19. One way delay ~ 10 ns measurement precision ETOMIC the European Internet experimentation infrastructure www.etomic.org

  20. Online demo:One-way delay measurement between two Etomic nodes Define and launch the experiment

  21. GPS visibility information ETOMIC the European Internet experimentation infrastructure www.etomic.org

  22. Tracking topology changes ETOMIC the European Internet experimentation infrastructure www.etomic.org

  23. Experimental use cases Some ongoing topics

  24. 1. Testing a new available bandwidth meter • Upload your available bandwidth meter via the web interface. Deploy it to the sites of your choice. Book measurement time and schedule your experiment. ETOMIC the European Internet experimentation infrastructure www.etomic.org

  25. 2. Transport protocol testing • Upload a new protocol version as an experiment and test it in real Internet + custom designed cross traffic ETOMIC the European Internet experimentation infrastructure www.etomic.org

  26. 3. Network Tomography Goal: to resolve delaystatistics on internal network segments too, where we do not have monitoring stations Method: we send back-to-back packet pairs and measure their end-to-end delay at arrival with very high precision Key idea:delay correlation on the common segment for the packets in a pair ETOMIC the European Internet experimentation infrastructure www.etomic.org

  27. Google Map visualization tool ETOMIC the European Internet experimentation infrastructure www.etomic.org

  28. Online demo:One-way delay measurement between two Etomic nodes Check the experiment, plot the results
