RIPE Atlas Probes - Lottery Drawing
by Mirjam Kuehne 14 Jan '11

14 Jan '11

Dear colleagues, As announced during RIPE 61, we did a lottery drawing among the users that had an RIPE Atlas probe up in December 2010. If you want to know how we did it and (more importantly) if you won, you can find out on RIPE Labs: http://labs.ripe.net/Members/emileaben/ripe-atlas-ipad-lottery Kind Regards, Mirjam Kuehne RIPE NCC

RIPE NCC Demo Dates
by Daniel Karrenberg 04 Jan '11

04 Jan '11

Good morning, and a happy, healthy and prosperous 2011 to all of you! In 2011 we plan to develop RIPE NCC information services a little more interactively than before. We will solicit feedback from you actively and we want you to try our new services early, so we can develop what you like and discard what noone uses. To this end we will be holding public demo sessions once a month at 1130-1200 Amsterdam and on these dates: Tuesday 25th January Tuesday 22nd February Tuesday 22nd March Tuesday 19th April Tuesday 18th May Tuesday 14th June Tuesday 12th July Tuesday 9th August Tuesday 6th September Tuesday 4th October Tuesday 1st November (NB: During RIPE63) Tuesday 29th November Tuesday 27th December (tentative...) Save those in your calendar. We will be using Webex for these demos (ripencc.webex.com) and publish short summaries on RIPE Labs for those who cannot attend. We will also publish recordings of the demos with these notes. During the first demo I will give a short overview of our plans for this year. See you then Daniel

RIPE Atlas probes now on Five Continents
by Mirjam Kuehne 30 Nov '10

30 Nov '10

Dear colleagues, RIPE Atlas probes are now active on five continents. After the big run on the measurement probes during the RIPE Meeting in Rome, the deployment is a little slower than expected; but there is a steady stream of probes coming online. Probe hosts can win an iPad by keeping their probes up during December!

Thoughts on the Internet Measurement Ecosystem
by Richard L. Barnes 02 Nov '10

02 Nov '10

Dear MAT WG list, I'm writing to share with you some thoughts that Ian, Christian, and I have been discussing, about how to expand the RIPE TTM network, better integrate it with other measurement systems around the world, and generally knit the Internet measurement ecosystem into a more cohesive whole. We're planning to have some discussion on these topics at the upcoming RIPE meeting in Rome, but we wanted to throw this out to the list to give people an introduction and hopefully spark some early discussions. The network measurement landscape right now is a series of stove- pipes. RIPE has a measurement network; CAIDA, PlanetLab, and their academic peers have a few different networks; and commercial entities like Akamai, Google, and Skype all collect measurements of the network infrastructure as part of measuring their own products. Each of these entities collects its own measurements, does its own analysis, and publishes its own results, independent of other measurements going on in the network. The result of this situation is that Internet measurement systems don't measure the Internet all that well. The Internet is a huge, diverse place, and each stove-pipe covers only a slice of it. Measurements on PlanetLab cover academic networks pretty well, but not home broadband networks. Web measurements from Akamai tells us a lot about the web, but little about VoIP or other real-time applications. Analytics aren't comparable because they're compared on the basis of completely separate data. So the question arises: How can we as a community work together to create a global network measurement ecosystem that facilitates near- real-time network analytics based on observations from points distributed over a large, diverse portion of the infrastructure? One could imagine a few possible realizations of this concept, for example: 1. A system for federating measurement systems, allowing them to share measurements in large volumes and in near-real-time. 2. Individual measurement systems and consumers of measurements could join together in something like the DNS OARC, under a common sharing agreement. 3. A central clearing-house for measurements, where some entities throw measurements in, and other entities get notifications when measurements of interest arrive. (I think of these three examples as analogies to private interconnects, peering points, and route servers, respectively.) There are bound to be several other paths with different trade-offs, and we welcome suggestions. There are clearly several interesting problems to solve in the development of this framework. In addition to the raw technical questions of how much data can be collected and distributed, there are thorny issues around how to incentivize participation, and how to protect the privacy of end users and the anonymity of contributors. We have some hope that these issues are surmountable, and looks forward to discussions on the list and in Rome. One final note: This discussion is closely related to the work that the RIPE NCC has been doing to expand their measurement network, e.g., through the RIPE ATLAS project: <http://labs.ripe.net/Members/dfk/active-measurements-need-more-vantage-poin… > What we're going after here is more general, looking at how projects like RIPE ATLAS and the traditional RIPE TTM could integrate more globally. Thanks for taking the time to read this, and please provide feedback. Even a simple "Yes, this is great", or "No, go away" would help us gauge whether there's any interest in the community. Sincerely, MAT WG chairs Christian Kaufmann Ian Meikle Richard Barnes

Bandwidth measurements
by Andrei Sukhov 14 Jul '10

14 Jul '10

Hi Henk, It is again me, Andrei Sukhov. Earlier our team tries to add mechanism of bandwidth measurements to RIPE Test Box data. We found a method how to calculate an available bandwidth from delays of different sizes of packets. Our report has been submitted in Berlin and Lisbon RIPE meetings. After Lisbon we have made additional experiments and compare our results with well-known pathload utility. The area of applicability of our method will be also found. All our results are included in paper that is attached to this letter. I would like to ask how our method may be used in RIPE Test Box for calculation of available bandwidth. Probably we should to make a report on IETF session (in Beijing ?). Please, give us an advice. Sincerely, Andrei Sukhov
