The definition of a network management datastore architecture (NMDA) has been published [RFC 8342]. We believe this is one of the more important RFCs we 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 May 2016 but the discussions have a much longer history.
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.
The EU funded LEONE project (2012-2015) contributed to the development of standards for large-scale measurements of Intern et performance, produced by the LMAP working group of the IETF. The key specifications, the LMAP information model [RFC8193] and the LMAP YANG data model [RFC8194], 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.
Vaibhav Bajpai presented a paper summarizing his PhD thesis at the IFIP/IEEE International Symposium on Integrated Network Management (IM 2017) and he received the best dissertation paper award.
We helped to organize a Dagstuhl seminar on Using Networks to Teach About Networks, which took place March 12–15, 2017. During the seminar, we discussed the different approaches to teach computer networking and how to best use of online resources to better educate students. For details, see the seminar report.
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.
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.
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.
Our research group is taking an active leadership role in the organization of some key scientific events this year: We are involved in the organization of the demo track of the IFIP/IEEE International Symposium on Integrated Management (IM 2015), which takes place in Ottawa (Canada) in May 2015. We co-chair the technical program committee of the 11th International Conference on Network and Service Management (CNSM 2015), which takes place in Barcelona (Spain) in October 2015.
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.
