Lessons Learned From Using the RIPE Atlas Platform for Measurement Research

We gave a talk in which we share our experiences and lessons learned from using the RIPE Atlas platform for conducting measurement research. We describe how subtle rate limits can affect experiment design. We show how calibration of probes from hardware revision down to the firmware version is useful when analyzing measurement results. We describe the usefulness by showing how different hardware revisions affect measurement results. We show how per-hop aggregation mistakes during data analysis can have impacts on measurement results.

Dagstuhl Seminar: Global Measurement Framework

We participated in a Dagstuhl seminar on Global Measurements Framework from November 17-20, 2013. The seminar discussed challenges in running large-scale measurement platforms, the associated privacy issues, with a particular focus on how to make it more useful by regulators, Internet service providers, and network users.

Measuring Happy Eyeballs at RIPE 66

Vaibhav Bajpai gave a talk about his work on measuring the effectiveness of happy eyeballs at the RIPE 66 meeting. The IETF has developed solutions that promote a healthy IPv4 and IPv6 co-existence. The happy eyeballs algorithm for instance, provides recommendations to application developers to help prevent bad user experience in situations where IPv6 connectivity is broken. We study the effectiveness of the happy eyeballs algorithm. A recording of the talk can be found on Vimeo.
