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.

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.

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

NSID option on the RIPE Atlas SOA measurements of the root servers
by Chris Amin 24 Jul '17

24 Jul '17

Dear colleagues, RIPE Atlas is currently running a series of DNS SOA built-in measurements* towards all of the root servers from all probes. During the recent DNS measurements hackathon** it became apparent that for some use cases it would be useful to have SOA queries from all probes with the NSID EDNS option set, in order to be able to match up responses with the particular responding instances in an anycasted (or load balanced) setup. We would like to ask for feedback on two alternative options for implementing this change. They are: 1) Enable the NSID option for the existing built-in measurements towards the nine root servers which support it. 2) Start a new set of built-in measurements towards the nine root servers which support NSID. The advantages of option (1) are that it will be possible to compare and contrast the two sets of results, and that historical data for the existing built-ins will remain consistent with the current results. A very simple analysis shows that there is no overall increase in query error rates through enabling NSID, but there are bound to be individual marginal cases where queries fail or produce different results with NSID set but succeed without it. The advantages of option (2) are that there will be no increase in result storage usage -- the current IPv4+IPv6 UDP SOA built-ins towards the nine supporting root servers adds up to about 80 results per second (~1.5% of the total results in the system). This could potentially be mitigated by reducing the frequency for these new measurements, but perhaps more important than the slightly increased load is the potential user confusion caused by generating and providing two very similar sets of measurements. Please let us know if you have any preference for which way we go on this, particularly if you have a (current or future) use case for this kind of data. Kind regards, Chris Amin RIPE NCC * https://atlas.ripe.net/docs/built-in/ ** https://labs.ripe.net/Members/becha/results-dns-measurements-hackathon

Fwd: [AfrICANN-discuss] AFRICOMM2017: Call for papers on Internet measurements
by Amreesh Phokeer 03 Jul '17

03 Jul '17

---------- Forwarded message ---------- From: Amreesh Phokeer <amreesh(a)afrinic.net> Date: Mon, Jul 3, 2017 at 12:17 PM Subject: Fwd: [AfrICANN-discuss] AFRICOMM2017: Call for papers on Internet measurements To: maprg(a)ietf.org Cc: nmrg(a)ietf.org {apologies for cross-posting} *{please circulate}* *Call for Papers* Workshop on Internet Measurements Research in Africa <http://africommconference.org/2017/show/IMRA> Internet measurements provide useful insights into the accessibility of the Internet (e.g. coverage of WiFi and cellular networks), performance (e.g. Internet throughput and latency) and Internet usage. Internet development campaigners, national regulators, and policy makers in the developing regions are recognising the crucial role that Internet measurement data can play in facilitating evidence-based policy-making and regulation. While the Internet ecosystem comprises a diversity of stakeholders and service providers, it is difficult for any single stakeholder to access all of Internet topology data without the cooperation of the rest of the Internet community. For this reason, appropriate acquisition of Internet data requires a variety of cooperative research methods, including wide distribution of Internet probes for technical measurements, located in diverse locations and networks, as well as region-specific techniques and demand-side surveys on Internet access and usage. The aim of the workshop is to facilitate discussions around mechanisms and challenges of measuring Africa’s Internet; to evaluate the breadth of Internet measurements research and to formulate strategic directions for such research in Africa; and to initiate and accelerate collaboration among Africa’s Internet measurements researchers. The workshop is calling for high-quality papers that are focused on Internet measurements research in Africa. Papers are invited on topics related to: ● End-to-end Internet performance metrics ● Internet topology characteristics, including peering and routing ● Application-level performance, including DNS, Web, CDNs, Cloud Computing ● Physical layer performance measurements, including for TVWS, WiFi, and 3G/4G ● Detection of middleboxes, censorship, and content filtering ● Data analytics for network monitoring, traffic analysis and network ● Network topology and performance visualization ● Internet access, use, and Quality of Experience (QoE) Submissions should be made electronically as PDF in the Confy system: IMRA track <http://confy.eai.eu/#conftrack-overview/conf/52446/cid/52366> . Papers will be selected through a single-blind peer-review process. Accepted papers will be included in the conference proceedings and will be published in Springer digital library. Important deadlines Submission 15 AUGUST 2017 Notification 30 AUGUST 2017 Camera-ready submission 30 OCTOBER 2017 Conference takes place 11-12 DECEMBER 2017 *Submission Guidelines and Paper Submission:* Please check the submission guidelines here: *http://africommconference.org/2017/show/initial-submission* <http://http//africommconference.org/2017/show/initial-submission> All the papers should be in English and formatted according to the Author's Kit IMRA papers should be submitted into 'IMRA track <http://confy.eai.eu/#conftrack-overview/track/1779/cid/52366>" in confy *Publications:* Accepted papers will be published in Springer's LNICST series and will appear in the SpringerLink, one of the largest digital libraries online that covers a variety of scientific disciplines, as well as in the EAI's own EU Digital Library (EUDL).

Dear colleagues, Last Thursday, 1 June, RIPEstat suffered from the longest service outage in years. Although the root cause was, in hindsight, trivial, it took more than three hours to fully recover. As unfortunate as this outage was, the situation yielded vital take-aways that will hopefully help prevent future outages.

color blindness and color meaning association
by Job Snijders 28 May '17

28 May '17

Hi all, TL;DR - red/green color palettes should be avoided in data visualiations, please pick something else! Yesterday I saw Christian Teuschel present on the "Jedi" tool at SINOG, and two things stood out: A) the data visualisations do not attempt to accomodate for people who are color blind, in fact, the worst colors possible were picked B) by using using common traffic light colors (green, orange, red) an implicit judgement is made on the meaning of the data (traffic crossing an internet exchange was seemingly favored over private peering) To point (A) - red–green color blindness which affect a substantial portion of the human population. In the US, about 7 percent of the male population (or about 10.5 million men) and 0.4 percent of the female population either cannot distinguish red from green, or see red and green differently from how others do (Howard Hughes Medical Institute, 2006). There are quite some pointers as to how to design color palettes which accomodate everyone. http://www.somersault1824.com/tips-for-designing-scientific-figures-for-col… http://blog.usabilla.com/how-to-design-for-color-blindness/ B) As I understand the "Jedi" tool, it shows matrixes of what traffic between atlas probes leaves the country, and what traffic remains within the country - offering insight into a reflection on a country's internal routing arrangements. I'm a big fan of keeping local traffic local, so the tool certainly has value. However, the tool displays traffic which passes over an IXP within the country as green, and traffic that says within the country but didn't cross an IXP as "orange". Since the majority of internet traffic flows over direct, private interconnections between ASNs, signifying that traffic as "orange", has the potential to be taken as a "wrong", rather then as an arbitrary datapoint. I suggest that the Jedi tool either uses the same color for ixp and non-ixp "within country" traffic (and perhaps a small icon is used to signify the additional data attribute that an IXP was observed in the traceroute), or that the jedi tool uses entirely arbitrary colors that have no inherent meaning like the traffic light colors do. Kind regards, Job
