Measuring Webpage Similarity from Dual-Stacked Hosts from Vaibhav Bajpai on Vimeo.

In this talk, we compare the similarity of webpages delivered over IPv4 and IPv6. It was presented at the RIPE 72 plenary in Copenhagen.

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

Vantage Point Selection for IPv6 Measurements: Benefits and Limitations of RIPE Atlas Tags from Vaibhav Bajpai on Vimeo.

In this talk, we show an application of system tags by performing vantage point selection of dual-stacked probes. This 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. It was presented at the MAT working group at RIPE 72 in Copenhagen.

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. Here is a picture from the event:

Measurement Research within the Python3 Ecosystem

Measurement Research within the Python3 Ecosystem from Vaibhav Bajpai on Vimeo.

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.

Lessons Learned From Using the RIPE Atlas Platform for Measurement Research

Lessons Learned From Using the RIPE Atlas Platform for Measurement Research from Vaibhav Bajpai on Vimeo.

In this talk 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

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. Here is a picture from the event:
