Measuring Webpage Similarity from Dual-Stacked Hosts

June 1st, 2016 Comments off

We presented our work on measuring webpage similarity delivered over IPv4 and IPv6 at the RIPE 72 plenary in Copenhagen. A recording of the talk can be found on Vimeo.

Vantage Point Selection for IPv6 Measurements: Benefits and Limitations of RIPE Atlas Tags

June 1st, 2016 Comments off

We discussed the usage of system tags for performing vantage point selection of dual-stacked probes. Our exploration reveals how with around 2K dual-stacked probes, RIPE Atlas provides the richest source of vantage points for IPv6 measurement studies. User tags on the other hand are based on a manual process which is largely dependent on proactive participation of probe hosts. We show that user tags tend to become stale over time. This work was presented at the MAT working group at RIPE 72 meeting in Copenhagen. A recording of the presentation can be found on Vimeo.

Dagstuhl Seminar: Global Measurements: Practice and Experience

January 19th, 2016 Comments off

We helped organize a Dagstuhl seminar on Global Measurements: Practice and Experience from January 04 – 07, 2016. This was a followup of the seminar on Global Measurement Framework. The second seminar aimed at discussing the practical experience gained with building global measurement platforms. It brought together people who are actively involved in the design and maintenance of global measurement systems, who do research on the data delivered by global measurement systems, and who use data derived from global measurement systems in order to manage networks or services or as input for regulatory decisions.

Measurement Research within the Python3 Ecosystem

November 21st, 2014 Comments off

In this talk, we present a set of tools that we find useful for measurement research and would like to share them with the larger RIPE community. Given the nature of the talk, we will make a live demo of running code snippets using the IPython notebook. A recording of our presentation can be found on Vimeo.

Lessons Learned From Using the RIPE Atlas Platform for Measurement Research

May 16th, 2014 Comments off

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. A recording of the talk can be found on Vimeo.

Dagstuhl Seminar: Global Measurement Framework

December 29th, 2013 Comments off

We participated in a Dagstuhl seminar on Global Measurements Framework from November 17 – 20, 2013. The seminar discussed challenges in running a large-scale measurement platform, its associated privacy issues, with a particular focus on how to make it more useful within the regulators, ISPs, and end-users community.
