RIPE Atlas Software Probes
by Philip Homburg 13 Feb '20

13 Feb '20

Dear colleagues, We are glad to announce that, after several months of development and testing, we are now accepting applications for RIPE Atlas software probes. With several different installation options to choose from, software probes provide future hosts a whole new way to get involved with RIPE Atlas. For more details, see our new article on RIPE Labs: https://labs.ripe.net/Members/alun_davies/ripe-atlas-software-probes Kind regards, Philip

New on RIPE Labs: Evaluating the Performance of NRENs in Deploying IoT in Africa
by Mirjam Kuehne 05 Feb '20

05 Feb '20

Dear colleagues, In this interesting study the authors (Marco Zennaro, Cristel Pelsser, Pietro Manzoni and Franck Albinet) used RIPE Atlas to measure delay and packet loss from African NRENs to The Things Network. Please find the results and some ideas for future work on RIPE Labs: https://labs.ripe.net/Members/marco_zennaro/evaluating-the-performance-of-n… Kind regards, Mirjam Kühne RIPE NCC

New on RIPE Labs: Modelling BBR’s Interactions with Loss-based Congestion Control
by Mirjam Kuehne 03 Feb '20

03 Feb '20

Dear colleagues, BBR has rapidly become a major player in Internet congestion control. BBR’s fairness or friendliness to other connections has recently come under scrutiny as measurements from multiple research groups have shown undesirable outcomes when BBR competes with traditional congestion control algorithms (CCAs). In this research Ranysha Ware, PhD student at Carnegie Mellon University, developed a model capturing BBR’s behaviour in competition with loss-based CCAs: https://labs.ripe.net/Members/ranysha_ware/modelling-bbr2019s-interactions-… Kind regards, Mirjam Kühne RIPE NCC

Looking for topology validation
by Kévin Vermeulen 23 Jan '20

23 Jan '20

Hi mat-wg, Our teams at Sorbonne Université and Naval Postgraduate School have developed a new Internet topology mapping tool, Diamond-Miner. Diamond-Miner[3] combines Paris Traceroute Multipath Detection Algorithm[1] and high probing rate Yarrp[2] techniques to trace the load balanced paths at Internet Scale. We are seeking now some validation of our inferences from operators, in particular the traceroutes links that we have found. We have developed a small website for operators to provide validation: http://heartbeat.planet-lab.eu:8000 You can either publicly submit the validation on the website or send us an email to kevin.vermeulen(a)sorbonne-universite.fr . You will find all the details on the website, do not hesitate to ask if you have further questions. Thanks in advance, Kevin [1]: https://arxiv.org/pdf/1809.10070 [2]: http://rbeverly.net/research/papers/yarrp-imc16.pdf [3]: https://www.usenix.org/conference/nsdi20/accepted-papers

New on RIPE Labs: The Debogonisation of 2a10::/12
by Mirjam Kuehne 17 Jan '20

17 Jan '20

Dear colleagues, Following the announcement of our plans to debogonise 2a10::/12, we have now shared the results of the tests we've been carrying out to check the usability of address space in this block. Read all about it on RIPE Labs: https://labs.ripe.net/Members/emileaben/the-debogonisation-of-2a10-12 Kind regards, Mirjam Kühne RIPE NCC
