Minutes from the MAT-WG session at RIPE62

19 May '11

Hi, Please find below the minutes from the working group session at RIPE62. Any comments or clarifications should be sent to the list. Thanks, Ian, Christian and Richard Measurement, Analysis and Tools Working Group RIPE 62, Amsterdam 5 May 2011, 16:00-17:30 Co-chairs: Richard Barnes, Christian Kaufmann, Ian Meikle Scribe: Devin Bayer, RIPE NCC Chat: Vasco Asturiano, RIPE NCC A. Co-Chairs' Intro Christian Kaufmann, WG co-chair, said they were seeking speakers for the upcoming ENOG conference. Christian’s presentation is available at: http://ripe62.ripe.net/presentations/129-MAT-Administrative.pdf B. RIPE Atlas update - Robert Kisteleki, RIPE NCC Robert’s presentation is available for download at: http://ripe62.ripe.net/presentations/174-20110505-kisteleki-atlas.pdf Florian Obser, Wyneken & Schaefer, commented that the probes couldn’t work with only IPv6 connectivity. Robert replied that they are working around the issues. Mohsen Souissi, AFNIC, asked about the criteria for the planned custom DNS measurements, especially in regards to hardware resources. Robert suggested discussing the possibilities and the Chair said it would be a good topic for the Measurements BoF. C. The Arbor ATLAS Initiative - Darren Anstee Darren’s presentation is available at: http://ripe62.ripe.net/presentations/127-Darren-Anstee-MAT-ATLAS-Under-the-… Richard Barnes (WG Chair) asked about IPv6 support. Darren said most features of the product are v6 capable now, but there isn't much data, either because providers are not using the product for v6 or there are related bugs. Honeypot sensors are v4 only. D. Home Network Monitoring - Renata Teixeira Renata’s presentation is available at: http://ripe62.ripe.net/presentations/182-teixeira-ripe-may2011.pdf Robert Kisteleki, RIPE NCC, said he was going to run it at home and compare the results to RIPE Atlas Lorenz Colitti, Google, asked if the tool could detect broken IPv6 connectivity at the home, to help prepare people for IPv6 day. Renata said the required measurements are taken, but no analysis is yet done. Ingvar Mattsson, Google, asked if the slowness seen by Genouille might be related to the buffer bloat problem. Renata replied that the netalyzer tool included in the profiler collects the relevant performance data and they also model the gateways with UPnP, so hopefully the analysis can be run later. Daniel Karrenberg, RIPE NCC, gave some encouragement and asked for periodic status reports on the MAT-WG mailing list. He also mentioned how the results are relevant to Atlas measurements and a possible future Atlas-like switch could sit between the router and the modem to get less biased results. E. NLNOG RING - Job Snijders, InTouch NV Job’s presentation is available at: http://ripe62.ripe.net/presentations/176-JobSnijders_NLNOG_RING_RIPE62.pdf Robert Kisteleki, RIPE NCC, commented that he would not want researchers to have shell access on his network. Job clarified that only operators get access to your machine, which should be placed in the same LAN as other hosted machines. Robert mentioned that it looks like Planet Lab and NL Lab. Richard Barnes, WG co-chair, commented that RING may be more diverse then those networks. Mohsen Souissi, AFNIC, asked if members are required to supply one machine per POP. Job said one machine is sufficient, but more are welcome. Richard Barnes said a list of current members would be appreciated. Daniel Karrenberg, speaking as a “netizen”, said he would be interested in joining RING, but can’t allow portmap scans on his boxes. >From chat, Christiaan Ottow, Pine Digital Security, also asked about limiting the allowed commands. Job answered that all the participants are from the land of the free, and restricting commands makes debugging harder. Randy Bush, Internet Initiative Japan, asked for a clarification about the requirement for a server to be in the DFZ with its own ASN. Job replied that the important thing is that the network and routing is controlled by the member, not another hosting provider. F. Emile Aben, RIPE IPv6 Measurements Emile’s presentation is available at: http://ripe62.ripe.net/presentations/162-2011-05-02-wv6day-ncc.pdf Mohsen Souissi, AFNIC, asked if the NCC is interested in providers with permanent IPv6-capable networks or just those switching it on for D-Day? Emile said they are interested in both. Lorenzo Colitti, Google, asked about getting fav icons for the status page. Emile said they will, but they are too small to notice MTU issues. Lorenzo said they expect to see packet loss for the 6to4 return path instead of latency changes. Lorenzo suggested trying to emulate the behavior of desktop OSes in addition to measuring them separately. For example, if you attempt first v6, then v4, you may experience a latency spike. Geoff Huston, APNIC, commented that the tools are concentrated on the end client, but content providers would like to know if their stuff would work before they turn it on. So at APNIC they twisted the tool around to allow content providers to do it. G. Christian Teuschel, RIPEstat - The Information Toolbox Christian’s presentation is available at: http://ripe62.ripe.net/presentations/178-ripestat_ripe62.key Richard Barnes asked that questions for RIPEstat be saved for the RIPE NCC Measurements BoF, thanks attendees, and closed the session.

suggestions for atlas service
by Piotr Strzyzewski 18 May '11

18 May '11

Hi Two suggestions: 1. Some looking-glass from the probe. Simpe ping/traceroute from the probe triggered from the web interface could be nice. 2. Better probe location display. Currently I host two probes, both 10cm one from each other, put into two different ASes. When I have put exactly the same geo data, the "display" mechanism put one of it onto the other one.

Hi, What I would be interested in is not only the rtd and tracroutes, but also the path-mtu from the atlas-device to the given or free-to-configure destinations. especially on my dsl connection the mtu is not always 1500.... regards, Harald -- Harald Michl <harald.michl(a)univie.ac.at> Vienna University - ACOnet www.ACO.net - VIX www.VIX.at Universitaetsstrasse 7, A-1010 Vienna, Austria, Europe Tel: +43 1 4277 - 14078 (Fax: - 9140) HM3550-RIPE

Some suggestions for stat.ripe.net
by Mauricio Vergara Ereche 12 May '11

12 May '11

Hi! I think that this is a great project! It has a nice interface and is very useful to get an "one page" info for everything. Excelent work! I have a few sugestions for the new system that I think can improve the value of this project: * Add an input field for each box, so the owner of the resource (or maybe anyone, I haven't think this too hard) can add more info about that particular item (ie: on geolocation, add the "true" location, on assignments within allocation - well, it's obvious :-P) * On the visibility test, when you get a "!" and a porcentage (let's say, 80%) it would be great to know if there was 80% of the probes over there that wasn't able to "see" the resource, or if 80% of the time was not visible, or if 80% of the times failed to check. Anyhow, I think it would be great to know more about this topic. If something failed, the hour of the fail, or the route to get to that resource. * Can you add a new box for do some kind of lookinglass over the resource from different locations/peers? that would be awesome! When i have to test some anycast cloud, i have to fly all over the looking glass that i can find, and then do my own analysis.

FW: IP Address utilization of The LIRs
by Ilyas . Celik 12 May '11

12 May '11

Dear all, There was a question probably from Daniel that he asked what LIR want to see on stats web page. As a LIR, I want to see IP address utilization for my AS when I query my AS from stat web site. It would be very nice if we get this information per prefix level. I think we can achieve this using netflow (without using confidential information) information. We can tell each LIR to send netflow data (only source,destination address and AS information. No protocol,port & traffic information to avoid confidential data) to distributed RIPE netflow servers. In the MAT-GW presentation, Arbor Atlas presented that they are getting hourly data from 129 different provider. I think we can use this information as well to find exact utilization of the IP Address space of each AS. I'm looking forward to go for IPv6 in my network as well but there is fact that most of the network, access devices doesn't support IPv6 yet. So there is still big demand for IPv4 and I'm sure we have some LIR that they are less than %50 utilization of IP Address. We can take this IPs from these LIRs if they don't have a plan to use this addresses recently and give it to LIRs which they are really need this. This will more give a time to world to move IPv6. Regards, Ilyas Celik
