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

De-bogonising 2a10::/12
by Emile Aben 16 Jan '20

16 Jan '20

Dear colleagues, We have now started de-bogonising 2a10::/12! As part of this, we are announcing a couple of prefixes out of 2a10::/12 from AS12654 (RIPE's Routing Information Service, RIS). Pingable targets have been configured in these prefixes, and we invite network operators to test for themselves whether this address space is reachable. The simplest way to do this would be to perform a ping6 to 2a10:4::1 . Using RIPE Atlas and RIS, we will also be carrying out our own tests in order to investigate connectivity and filtering for this address space. We plan to share our results with the RIPE community via RIPE Labs within the next few days. For those who want to do other testing, beyond the basic test described above, we have a total of 8 targets available for this, with 2 different prefix lengths and all variations of having ROUTE objects in the RIPE DB and/or ROAs. 2a10:3:4::1 /48 ROUTE object + ROA 2a10:3:5::1 /48 no ROUTE object + ROA 2a10:3:6::1 /48 ROUTE object + no ROA 2a10:3:7::1 /48 no ROUTE object + no ROA 2a10:4::1 /32 ROUTE object + ROA 2a10:5::1 /32 no ROUTE object + ROA 2a10:6::1 /32 ROUTE object + no ROA 2a10:7::1 /32 no ROUTE object + no ROA Kind regards, Emile Aben RIPE NCC

MAT WG as an advisory body for RIPE NCC tools
by Brian Trammell (RIPE) 22 Oct '19

22 Oct '19

Greetings, all, We ran out of time today to discuss the proposal I alluded to at the beginning of the meeting, so I'm taking it to the mailing list: I would propose that we make the role of MAT WG in providing information and advice to the RIPE NCC's tools teams more explicit. In this proposal, mat-wg(a)ripe.net mailing would be considered a primary channel for proposals for features for RIPE Atlas. These proposals would then be discussed on the list and/or during MAT WG meetings, and once the discussion on converges, the outcome passed to the RIPE NCC tools team as advice. This would turn the current process, where the tools team disseminates updates about current work and future plans, into a two way street. While I propose that this should be more explicit, I am not proposing that this be made more formal: this would not use the PDP, and would not be in any way binding on the NCC. What do you, the WG, think? Thanks, cheers, Brian (as MAT-WG co-chair)

Dear colleagues, We started a complete redesign of the RIPEstat user interface. With the prototype UI having received a lot of positive feedback, we’re still busy adding new features, one of which will allow users to switch between languages when using RIPEstat. As this is a first for us, here’s more detail on what we have in mind: https://labs.ripe.net/Members/stephen_suess_1/the-new-ripestat-in-other-wor… We will tell you more about this during the RIPE 79 MAT WG session on Thursday and look forward to your feedback.

Open Call for Presentations for MAT-WG
by Brian Trammell (RIPE) 29 Aug '19

29 Aug '19

Greetings, all, Our next meeting is at RIPE 79, on Thursday 17 October 2019 at 14:00, and it's time to pull together an agenda for it. Please send proposals for presentations at MAT WG to mat-wg-chairs(a)ripe.net. That said... we've actually almost *finished* pulling together an agenda for this meeting, so we're going to start doing something a little different. Nina and I have been running a queue for interesting future talks for a while (whether they be ideas we've had to solicit talks, proposals for talks we couldn't take at previous meetings, and so on), and we'd like to make that more explicit. So we're announcing that we take proposals for presentations at MAT WG *at any time* sent to mat-wg-chairs(a)ripe.net (don't worry, we'll still send reminders like this one each time a meeting is coming up :) ). When you propose a talk, please indicate whether you're only able to present at the next meeting, or whether you'd like us to keep it in the queue for future meetings if there's not room at the next one. Many thanks, cheers, Brian (as MAT-WG co-chair)
