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

Last call for presentations and Draft programme for RIPE 75
by Benno Overeinder 25 Aug '17

25 Aug '17

Colleagues, A list of currently accepted RIPE 75 presentations is now published at: https://ripe75.ripe.net/programme/meeting-plan/draft-programme/ There are still plenary, BoF, tutorial and workshop slots remaining for the final RIPE 75 programme and RIPE Programme Committee will accept new proposals until *6 September 2017*. This is our last call for you to submit your proposals. You can find the CFP for RIPE 75 below or at https://ripe75.ripe.net/submit-topic/cfp/, for your proposals for plenary session presentations, tutorials, workshops, BoFs (Birds of a Feather sessions) and lightning talks. Please also note that speakers do not receive any extra reduction or funding towards the meeting fee at the RIPE Meetings. Update to UAE DTCM requirements: It is now confirmed that a photocopy of speakers' passports is *not* required. Non-UAE/international speakers need only to provide: * Passport number * Date of birth * A short biography (at least 60 words) Residents of the UAE are required to upload a copy of their Emirates ID (in jpeg format). More details are available here: https://ripe75.ripe.net/attend/dctm-requirements Kind regards, Benno Overeinder RIPE PC Chair https://ripe75.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 75 will take place from 22-26 October in Dubai, UAE. 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 75. See the full descriptions of the different presentation formats, https://ripe75.ripe.net/submit-topic/presentation-formats/.

by Vesna Manojlovic 04 Aug '17

04 Aug '17

Dear colleagues, Today begins the newest edition of four-yearly Dutch summer camping conferences for and by hackers: SHA2017. http://sha2017.org/ Since there is an overlap between topics and participants within the RIPE community, this is an invitation to the talks and workshops - a small selection was recommended, from more then 200 lectures. There is a special sub-selection of workshops relevant to MAT-WG. Read more about it in this RIPE Labs article: https://labs.ripe.net/Members/becha/sha2017-hackers-camping-ripe-topics ... or if you are there too, get in touch :) Regards, Vesna Manojlovic Community Builder RIPE NCC

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
