New on RIPE Labs: Announcing Daily RIPE Atlas Data Archives
by Mirjam Kuehne 16 Feb '18

16 Feb '18

Dear colleagues, In this article we present a new way to access the dataset on the RIPE Atlas platform. Instead of fetching individual results from measurements using the available APIs, you can now download files containing public measurements for a given day. Please find more details on RIPE Labs: https://labs.ripe.net/Members/petros_gigis/announcing-daily-ripe-atlas-data… Kind regards, Mirjam Kühne RIPE NCC

New on RIPE Labs: OpenIPmap - A Collaborative Approach to Mapping Internet Infrastructure
by Mirjam Kuehne 14 Feb '18

14 Feb '18

Dear colleagues, OpenIPmap, the RIPE NCC’s tool for geolocating core Internet infrastructure, has undergone a full architectural overhaul. With a new set of APIs and interfaces designed to cater to the needs of all users, the system integrates various methods for estimating the geographical locations of IXPs, core routers and other components of Internet infrastructure. In this, the first of two RIPE Labs articles on the topic, we look at the evolution of OpenIPmap from its inception to today: https://labs.ripe.net/Members/jasper_den_hertog/openipmap-a-collaborative-a… Kind regards, Mirjam Kühne RIPE NCC

Call for presentations RIPE 76
by Benno Overeinder 23 Jan '18

23 Jan '18

Dear colleagues, Please find the CFP for RIPE 76 below or at: https://ripe76.ripe.net/submit-topic/cfp/. The deadline for submissions is *11 March 2018*. Please also note that speakers do not receive any extra reduction or funding towards the meeting fee at the RIPE Meetings, see the "Speakers" paragraph in CFP for more information. Kind regards, Benno Overeinder RIPE PC Chair https://ripe76.ripe.net/ripe-pc/ -------------------->>><<<-------------------- Call for Presentations A RIPE Meeting is an open event where Internet Service Providers, network operators and other interested parties get together. Although the meeting is mostly technical, it is also a chance for people to meet and network with others in their field. RIPE 76 will take place from 14-18 May in Marseille, France. The RIPE Programme Committee (PC) is now seeking content proposals from the RIPE community for the plenary sessions, BoFs (Birds of a Feather sessions), panels, workshops, tutorials and lightning talks at RIPE 76. See the full descriptions of the different presentation formats, https://ripe76.ripe.net/submit-topic/presentation-formats/. Proposals for plenary sessions, BoFs, panels, workshops and tutorials must be submitted for full consideration no later than *11 March 2018*. Proposals submitted after this date will be considered depending on the remaining available space in the programme. The PC is looking for presentations covering topics of network engineering and operations, including but not limited to: - IPv6 deployment - Managing IPv4 scarcity - Data centre technologies - Network and DNS operations - Internet governance and regulatory practices - Network and routing security - Content delivery - Internet peering and mobile data exchange - Connected Things (aka. Internet of Things - IoT) Speakers Presenters, RIPE Working Group Chairs and the RIPE Programme Committee are required to cover their own costs to attend a RIPE Meeting (meeting ticket, travel and accommodation). We have various ticket options available depending on your needs. In extraordinary circumstances, the RIPE Chair can waive the meeting fee for presenters. These requests are dealt with on a case-by-case basis via pc(a)ripe.net. Also note that, on an individual basis, participants can apply for a RIPE Fellowship to develop their professional or academic career. For more information, please visit: https://www.ripe.net/participate/ripe/ripe-fellowship Submissions Presenters should be clear on whether they wish to submit a presentation for a plenary or working group (WG) session. At present, most working groups will solicit policy proposals, discussion points or other content directly via their mailing lists. If you’re not sure what kind of session you should be presenting at, please visit: https://ripe76.ripe.net/plenary-or-wg/ RIPE Meeting attendees are quite sensitive to keeping presentations non-commercial, and product marketing talks are strongly discouraged. Repeated audience feedback shows that the most successful talks focus on operational experience, research results, or case studies. For example, presenters wishing to describe a commercial solution should focus on the underlying technology and not attempt a product demonstration. Presenters should indicate how much time they will require. In general, the time allocated for the different presentation formats is as follows: - Plenary presentations: 20-25 minutes presentation with 5-10 minutes discussion - Tutorials: up to two hours (Monday morning) - Workshops: one hour (during evening sessions) to two hours (Monday morning) - BoFs: approximately one hour (during evening sessions) - Lightning talks: 10 minutes total for both presentation and any discussion The following general requirements apply: - Proposals must be submitted using the meeting submission system, https://ripe76.ripe.net/submit-topic/ - Lightning talks should also be submitted using the meeting submission system (https://ripe76.ripe.net/submit-topic/) and can be submitted any time up to and including the meeting week. The allocation of lightning talks will be announced on short notice, in some cases on the same day but often one day prior to the time slot allocated. - Presenters who propose a panel or BoF are encouraged to include speakers from several (perhaps even competing) companies and/or a neutral facilitator. - All presentation proposals will only be considered by the PC if they contain at least draft presentation slides (slides may be updated later on). For panels, proposals must contain a clear description, as well as the names of invited panellists, presenters and moderators. If you have any questions or requests concerning content submissions, please email pc(a)ripe.net. -- Benno J. Overeinder NLnet Labs https://www.nlnetlabs.nl/

Deadline extended: Call for applications for TMA 2018 Shadow PC
by Andra Lutu 18 Jan '18

18 Jan '18

Network Traffic Measurement and Analysis Conference (TMA Conference 2018) June 26-29, 2018, Vienna, Austria http://tma.ifip.org/2018/ TMA 2018 Shadow PC ================== To provide an educational experience by introducing students to a review process and to subsequently train the next generation of program committee (PC) members, the TMA 2018 TPC would like to make submitted papers available to the shadow PC. Shadow PCs allow students and others interested in future PC service to read submitted papers and go through the reviewing process, ultimately arriving at a shadow conference program. This opportunity allows future PC members to learn first-hand about the peer-review process and gain experience as a reviewer. The shadow PC process is run on a different system and the shadow PC reviewers will not have any access to the real reviews, the names of the real reviewers, or any other data such as relative rankings. Shadow PC reviewers will have to abide by the same rules and restrictions applicable to regular PC members. This includes, but is not limited to, rules against discussing the papers outside of the PC context, or using in any way results from reviewed papers before such papers have been published. Delegated reviews (i.e., external reviews) are not allowed for the shadow PC. A submitted paper is made available to the shadow PC by default; authors will have the opportunity to opt-out during the paper submission process. Shadow reviews for papers that are reviewed by the shadow PC will be sent out after the actual TMA’18 review process. Authors who have participated in previous shadow PCs have found the additional reviews helpful; however, these reviews will have no bearing on acceptance to the technical program. You can directly contribute to a successful shadow PC and benefit from the additional feedback on your submission by making your paper available to the shadow PC with no extra overhead. Simply indicate your choice in the HotCrp submission site. Shadow PC Chairs (contact: shadow-tma18(a)cm.in.tum.de) -- Vaibhav Bajpai (Technische Universität München) -- Andra Lutu (Simula Research Laboratory) -- Oliver Hohlfeld (RWTH Aachen University) Call for Applications ===================== Following a successful model used at other premier technical conferences such as SIGCOMM, CoNext, EuroSys, NSDI, and IMC, TMA will be organizing its first Shadow Program Committee in 2018. The Shadow PC will consist of PhD students, early-career academics, and junior researchers and will provide reviews on a subset of submissions to the conference. Paper authors can choose to opt-out for shadow reviews. The TMA Shadow PC will function much like an independent version of the “Senior” PC, including holding an in-person or online PC meeting and deciding the program of papers it would have selected (note that only authors will learn the “shadow” fate of their own papers, which will have no impact on the actual TMA PC process). Shadow PC members will be expected to review a full load of 5-10 papers (depending on the number of submissions selected for the Shadow PC process) on time and participate in online discussion, as well as follow the ethical standards of peer review. Shadow PC members will also be required to do a small amount of reading about the PC process. Shadow PC members must respect the anonymity of the review process and not share which papers they have reviewed or solicit sub-reviews. Shadow PC members who do not adhere to the review deadlines will be excluded from the process. Shadow PC reviews will be made available (anonymized) to the authors. The Shadow PC meeting will likely be held on March 28 in Berlin co-located with PAM (details TBD). Shadow PC members should attend in-person or online (some travel grants will be available to support attendance). Shadow PC members will not attend the Senior PC meeting, and the Shadow PC program acceptance decisions will not be made available publicly. However, some PC members might attend the shadow PC meeting to help with the discussions. If you are interested in participating, please apply by uploading your application material to http://hotcrp.cm.in.tum.de/shadow-tpc-tma18 submission site by Jan 15th, 2018, Midnight Pacific time. Your application should consist of a single PDF file which includes a CV and a brief (0.25-1 pg) motivation statement explaining why you’d like to participate in the shadow PC. Be sure to include your name, position/year of study, areas of research experience, publications (feel free to include tech reports, papers under submission/preparation, and unreviewed manuscripts, as long as you indicate them as such) or past reviewing experience (ok to have none). Important Dates =============== Deadline to Apply for Shadow PC: *February 1, 2018* Notification of Acceptance to Shadow PC: *February 8, 2018* Shadow Review Period: February 17 – March 21, 2018 Shadow Discussion Period: March 21 – March 27, 2018 Shadow PC Meeting: March 28, 2018 -- Andra Lutu Postdoctoral Fellow Mobile: +47 458 36 244 Simula Research Laboratory Visiting address: Martin Linges vei 17, 1364 Fornebu, Norway Mailing address: P.O.Box 134, 1325 Lysaker, Norway ----------------------------------------------------------------------- Homepage: https:/www./simula.no/ <http://simula.no/>

DMARC Solution Applied to this Mailing List
by Adam Castle 18 Dec '17

18 Dec '17

Dear Working Group, As more email providers enable Domain Message Authentication Reporting & Conformance (DMARC), some people find they can no longer receive emails from the mailing lists they are subscribed to. We have deployed a Mailman setting change to address this problem. After consultation with the RIPE Working Group Chairs, we have enabled the DMARC "Munge From" setting on all RIPE mailing lists. This means that if your email service provider has DMARC enabled, you will continue to receive all emails sent to this mailing list, but the "From" part of the header will change. If you don't have DMARC enabled, you won't see any change to the emails you receive from this mailing list. You can find more information about how we have been handling DMARC in the following RIPE Labs articles: https://labs.ripe.net/Members/adam_castle/dmarc-and-the-ripe-ncc https://labs.ripe.net/Members/adam_castle/ripe-mailing-lists-and-dmarc To ensure all working group participants are aware of the changes, I am sending this mail to all working groups. If you have any questions or encounter any issues on this mailing list, please let me know. Many thanks. Adam Castle Web Services Manager RIPE NCC

New on RIPE Labs: Measuring your Web Server Reachability with TCP Ping
by Mirjam Kuehne 27 Sep '17

27 Sep '17

Dear colleagues, HTTP measurements from RIPE Atlas probes are only possible towards RIPE Atlas anchors. However, when it comes to measuring the connectivity and latency of web servers on the network level, an alternative exists, which we call TCP Ping: a traceroute with special options that mimic the TCP handshake that takes place when an HTTP connection is established. In this RIPE Labs article we compare the results of large scale HTTP and TCP Ping measurements: https://labs.ripe.net/Members/wilhelm/measuring-your-web-server-reachabilit… Kind regards, Mirjam Kuhne RIPE NCC

Call for MAT CoChair candidates
by ckaufman 12 Sep '17

12 Sep '17

Dear MAT WG, the time has come to make my “Chair” vacant and bring some fresh blood into the MAT WG:-) As you might remember I am one of original three MAT WG CoChairs since the MAT was rechartered out of the original Test Traffic WG at RIPE60 in Prague. Originally I was chairing together with Ian Meikle and Richard Barnes which left over the years and where eventually succeeded by Nina Bargisen. (Job description for interested Candidates:-)) I have done the job now for 7,5 years prepared the session, chaired the session, answered emails, welcomed new attendees at RIPE Meetings, represented the WG at ENOG and sometimes other conferences, had countless conversation with Daniel, Robert, Kaveh and of course Vesna about RIPE Atlas and the Anchors and about further and future collaboration. Attended RIPE Hackathons. Participated in the PDP review and in the WG collective as your representative, etc. These are all tasks a MAT WG CoChair does do to one or the other degree, and which you should be interested in if you apply for it. In the last years we came up with an election process which was approved by you and used when we elected Nina and which I want to use now for replacing me. We will go through the process as described below and ideally present the new WG CoChair at the next WG Session in Dubai. After the Dubai Meeting I will then officially step down. The process: 1. A call for interested parties is made on the WG mailing list at three yearly intervals, or as needed 2. Interested parties have 2 weeks to make their interest known via the mailing list 3. The MAT-WG chairs issue a call for discussion as per normal. WG members express their approval or otherwise of the presented candidates. 4. After two weeks the chairs declare consensus as they would do for a policy proposal As a remainder our Charter and Website can be found at: https://www.ripe.net/ripe/groups/wg/mat <https://www.ripe.net/ripe/groups/wg/mat> and the official Job description at: https://www.ripe.net/ripe/docs/ripe-542 <https://www.ripe.net/ripe/docs/ripe-542> Please feel free to nominate yourself if you are interested or shanghai others ( with their approval:-)) till the 11th September. Thx a lot and it was a pleasure to serve you. Christian Kaufmann MAT WG Co-Chair PS: I want to thank the RIPE NCC for their support over all the years, without them there would be no MAT WG, especially Mark Dranse who inspired me to start this journey, Daniel for starting RIPE Atlas and his vision, Rob B. for his wisdom as RIPE Chair, Robert and Kaveh for their never ending support and input, Vesna for her spirit and energy and for bringing so many people together, Amanda for the minutes and Hans Petter for doing an excellent job as a WG Chair Dompteur. And last but not least Nina for continuing the WG and her support in the last years.

RIPE NCC::Educa are free, online learning events that bring industry experts together to share insight, expertise and best practice with those that want more in-depth knowledge on a particular subject. Our first event focuses on RIPE Atlas on Thursday, 5 October from 8:00 - 13:00 UTC. Reserve your place here: https://www.ripe.net/support/training/ripe-ncc-educa <https://www.ripe.net/support/training/ripe-ncc-educa> You can join us for one session, multiple sessions or the full programme. We’re updating the agenda constantly, so be sure to check here for the latest additions: https://www.ripe.net/support/training/ripe-ncc-educa/agenda <https://www.ripe.net/support/training/ripe-ncc-educa/agenda> For more information on RIPE NCC::Educa, check out our RIPE Labs article: https://labs.ripe.net/Members/sandra_bras/introducing-ripe-ncc-educa <https://labs.ripe.net/Members/sandra_bras/introducing-ripe-ncc-educa> If you have any questions, please get in touch with us: <e-learning(a)ripe.net <mailto:e-learning@ripe.net>> Warm regards, Sandra Brás E-Learning Program Manager RIPE NCC

Plan to Implement RIPE Atlas WiFi Measurements
by Robert Kisteleki 30 Aug '17

30 Aug '17

Dear colleagues, We wanted to update the community and let you know that we plan to start work on the proposed experiment with WiFi measurements in mid-2016. As we communicated in a recent RIPE Labs article, we will work with GÉANT as a test partner to learn more about the operational effects of introducing WiFi measurements to the RIPE Atlas system, in addition to the benefits we believe this could provide for the entire RIPE Atlas community. Please see the article for more details if you are interested: https://labs.ripe.net/Members/suzanne_taylor_muzzin/ripe-atlas-wifi-measure… We will continue to update you once we’ve begun work on this plan, and we welcome your comments in the meantime. Regards, Robert Kisteleki RIPE NCC

Are you using passive on-path RTT measurements in day-to-day operations?
by Brian Trammell 29 Aug '17

29 Aug '17

Greetings, all, I've proposed a lightning talk on this subject for Dubai, but it occurred to me that this working group might be a better place to answer this question: how prevalent is the use of passive latency measurement (e.g., by looking at DNS request/response times, or TCP seq-ack / timestamp delays) in everyday network operations, and for what is it commonly used? I ask this question in the context of a very specific design proposal before the IETF's QUIC working group. QUIC encrypts almost all of its header information beyond that needed for its crypto handshake, which makes equivalent techniques to those used in TCP impossible: you see no ACK numbers, and no timestamps, so it's impossible to match an upstream QUIC packet with its downstream counterpart. However, a recently proposed addition to the spec (https://github.com/quicwg/base-drafts/pull/609) would add a single bit to the header which would be explicitly intended for passive round trip time measurement. Since this adds a small amount of complexity to the wire image, one useful piece of input to the decision whether or not to add this measurability is how useful it is, in terms of operational impact of having passive measurability go away as TCP flows are replaced by QUIC flows. Thanks, cheers, Brian
