RFC #42 is RFC 8342

March 18th, 2018 Comments off

My 42nd RFC has been published and it got the number RFC 8342. Despite the funny number, I believe this is one of the more important RFCs I have worked on since it tells us how to think about configurations and their relationship to operational state. A few more RFCs will appear during the coming weeks providing the technology extensions that allow us to use the new framework in practice. Work on this document started with a trip to Stockholm in 2016 but the discussions have a much longer history and it feels good to have them settled and the document published.

Our research on YouTube performance over IPv6 made it into the blog of the Asia-Pacific Network Information Centre (APNIC). You can find the blog post here.


LMAP Information Model and Data Model Published

August 23rd, 2017 Comments off

The EU funded LEONE project (2012-2015) contributed to the development of standards for large-scale measurements of Internet performance, produced by the LMAP working group of the IETF. The key specifications, the LMAP information model and the LMAP YANG data model, have been published as RFCs just a few days ago. It took roughly five years from the start of the formation of the working group until the publication of the core specifications. The first version of the information model was posted roughly 2.5 years before publication of the final document. This example shows that initiating and completing standardization work within the lifetime of EU projects is just not realistic.

Dagstuhl Seminar: Using Networks to Teach About Networks

April 3rd, 2017 Comments off

We helped organize a Dagstuhl seminar on Using Networks to Teach About Networks, which took place March 12 – 15, 2017. We discussed the different approaches to teach computer networking and the use of online resources to better educate students.


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.


IM 2015, CNSM 2015, Dagstuhl Seminar 16012

February 7th, 2015 Comments off

Our research group is taking an active leadership role in the organization of some key scientific events this year:

For the IM 2015 demo track, we received a good number of submissions and the demo selection process is well underway. For CNSM 2015, we hope to attract a good number of submission. CNSM is the most selective conference in the field of network and service management research. It is important for every researcher working on topics related to network and service management to present and discuss their work at this key event. The paper submission deadline is April 24th, 2015.


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.
