by Ian Meikle 26 Apr '11

26 Apr '11

Dear all, Please find the minutes from our last session below. Apologies for the delay in posting these. If you have any objections or comments please post them to the list. Regards, Ian, Christian and Richard ------------ Measurement, Analysis and Tools Working Group RIPE 61, Rome Thursday 18 November 2010, 16:00-17:30 Scribe: Rene Wilhelm, RIPE NCC Chat: Chris Buckridge, RIPE NCC A. Administrative Matters Co-chair Ian Meikle welcomed attendees and opened the first session of new MAT Working Group. B. Traffic Identification Engine - Alberto Dainotti, University of Naples The presentation is available at: http://ripe61.ripe.net/presentations/266-tie-ripe-v5.pdf Alberto presented the research done in the University of Naples on traffic classification. They would appreciate feedback from the operator community. What are the needs of and technical problems encountered by ISPs in the field of traffic classification? The group is also interested in collaborations with service providers. Steve Nash from ARBOR Networks stated he was interested to talk to Alberto about the plug in concept. C. Neustar Anycast Statistics- Edward Lewis, Neustar The presentation is available at: http://ripe61.ripe.net/presentations/351-RIPE61MATWG-Lewis.pdf Edward Lewis talked about the DNS statistics gathering system Neustar have in place for about a year now. Daniel Karrenberg from the RIPE NCC asked if the software was in a proprietary package; if there was a chance to get insight into the specifications of how Neustar return things so others could learn and build something themselves. Edward Lewis replied there is no deliverable software. It's not just a package; it's built into the core. Providing an overview of what the product does would be more of a sales presentation. D. Information Services Update - Sean McAvoy, RIPE NCC The presentation is available at: http://ripe61.ripe.net/presentations/352-Information_Services_Update_RIPE_6… Sean McAvoy gave an update on developments in RIPE NCC Information Services. An improved UI for the DNSMON service has been released as public beta. E. IPv6 Network Measurement - Owen DeLong, Hurricane Electric The presentation is available at: http://ripe61.ripe.net/presentations/353-RIPE61_Measurement.pdf Owen DeLong presented some statistics on IPv6. Countries on v6, growth in routing table, types of network traffic and signs of a first (useless) attack in IPv6. F. Visualizing geolocated Internet measurements - Claudio Squarcella, CAIDA The presentation is available at: http://ripe61.ripe.net/presentations/201-preso.pdf Claudio presented some new techniques to visualize Internet measurements based on geographical location. Klaus Darilion, from nic.at, enquired about the software used for these visualisations. Claudio explained he used Google web toolkit, the Raphael JavaScript library (for graphics) and Java code translated into Javascript. G. Atlas Technical Details - Robert Kisteleki, RIPE NCC The presentation is available at: http://ripe61.ripe.net/presentations/269-20101118-RIPE61-MAT-Robert.pdf Robert presented the technical aspects of the Atlas project. Design principles as well as implementation details. Wolfgang Tremmel, via the chat, suggested to provide the firmware sources for download in order to prevent hacking. Daniel Karrenberg replied RIPE NCC is not going to provide the source code any time soon. Making RIPE Atlas open source at this moment, while it is just starting would put its success at risk. Someone could take the idea, the design and commercialise it into a competing product. Once the project has established itself, has sponsors and there is more experience, RIPE NCC will be very open to input and requirements from sponsors and the membership regarding these issues. Jelte Jansen from ISC asked how probe re-boots, which could be needed to recover from memory exhaustion, are going to be handled. Will users receive reboot request via e-mail? Robert explained that a watchdog timer handles this. The probe re-boots automatically, is back in business within a minute or so. Ruben van Staveren asked, via the chat, how fast RIPE NCC could provide updates in case of misbehaviour or security issues. Robert replied that the RIPE NCC could disable probes; if a probe is found misbehaving it can be taken off the measurement net immediately. Deploying a new firmware can be done within days, once it is ready. The actual development time for new firmware depends on the amount of changes needed. Daniel Karrenberg added that RIPE NCC does thorough testing before distributing new firmware to the production network. Richard Barnes from BBN commended the RIPE NCC on the design of the system. He stresses the major value of the Atlas network is in the large volume of data it produces. Next to graphical user interfaces and visualisations, he would like to see a programmatic interface, an API to access the raw data. H. Measurement Framework Proposal and Discussion - Daniel Karrenberg, RIPE NCC and the WG Co-Chairs There was a lively discussion on the proposal by the WG chairs of having a single platform that not only shows results from RIPE NCC tools, but also from other organisations, institutions who would be happy to share their data. Daniel added to that his vision of building a measurement community by providing the means to annotate, share and discuss results. This would be the place to go whenever something comes up, an anomaly or strange behaviour of the Internet. The attendees did not oppose the proposal, it was suggested to try it out and see how it evolves. Co-chair Richard Barnes reminded the audience of the mat-wg(a)ripe.net mailing list. He added that it has seen little traffic since the last RIPE meeting, but this will change as things get started. The list will be the venue for collecting community feedback on these topics. Also, RIPE NCC will report more often to the list. People are encouraged to subscribe to the mailing list and participate in the discussion. Richard thanked the audience for attending and closed the session.

Homenet Profiler: understand your home network better
by Renata.Teixeira＠lip6.fr 19 Apr '11

19 Apr '11

Dear colleagues, We need your help to conduct our research on home networking. We are working on ways to help home users diagnose problems in their home networks. The first step is to better understand the configuration of these networks. We developed a tool called HomeNet Profiler that collects information about the home network such as the device configuration, the quality of the wireless, and Internet access performance. When you run HomeNet Profiler, you will immediately have access to a report. HomeNet Profiler runs on most operating systems and it doesn't install anything in your computer. When you are at home, could you please run HomeNet Profiler from http://cmon.lip6.fr/hnp/ ? We would really appreciate your help and your feedback. Please help us by forwarding this message to others who may be interested. --The HomeNet Profiler team Lucas DiCioccio, Renata Teixeira, Catherine Rosenberg

29 Mar '11

Dear WG colleagues, RIPE62 will be held in Amsterdam 2-6 May 2011 ( http://www.ripe.net/ripe/meetings/ripe-meetings/ripe-62). The MAT WG session will be at 16:00 on Thursday 5 May. My co-chairs and I invite you to submit presentations or suggestions for content you would like to see in this session. As a reminder, the working group charter states: The purpose of the working group is to provide a forum in which the RIPE NCC and the community can collaborate in the areas of data, tools and analysis relating to the Internet and its infrastructure, with a loose focus on monitoring, diagnosis, analysis and forecasting. It is not the purpose of the working group to compare the performance of networks for marketing purposes. If you would like to contribute anything to our session at the next RIPE meeting please email mat-wg-chairs(a)ripe.net. Best regards, Ian Meikle Co-chair MAT Working Group

Comments on RIPEstat
by Richard L. Barnes 24 Mar '11

24 Mar '11

Hey all, This is the standard post-demo thread for comments on RIPEstat. Here are mine to kick things off: -- As I said on the call, it's not really clear right now what the purpose is of the "Query" link. I guess it could help me understand, but it would be extra useful to be able to tweak and re-query. Maybe this could show a text box with a "Re-query" button? -- It seems like visibility graph could be a good way to use ATLAS data? Of course, the ATLAS probes would have to start pinging a little more broadly. -- I like the path length graph a lot. It's kind of useful to have the graph fill in when you mouse over, but it might be nicer if you could show the data value when you mouse over a point, and if the fill could be translucent so that you could still see the other lines. Thanks, --Richard
