RIPE Atlas User-Defined Measurements BoF
by Vesna Manojlovic 12 Apr '12

12 Apr '12

Dear colleagues, We will be holding a session at the RIPE meeting for people interested in discussing user-defined measurements (UDM) with RIPE Atlas. Both beta testers and people who have not yet used UDM are welcome to attend. It is scheduled for Thursday, 19 April at 17:45 in the Grand Union Hall (main room). We will begin after the end of the Measurements, Analysis and Tools (MAT) working group session (which takes place in the same room). And, if you’re lucky, you might get to taste one of the limited edition Atlas beers we’ve got on offer! More details in the Labs article: https://labs.ripe.net/Members/becha/ripe-atlas-udm-bof Regards, Vesna

RIPE Atlas User-Defined Measurements Are Here!
by Vesna Manojlovic 11 Apr '12

11 Apr '12

Dear Atlas Hosts and Sponsors, We are pleased to announce the roll-out of user-defined measurements (UDM) for RIPE Atlas. As of today, all hosts and sponsors are invited to run custom measurements. To access UDM, either click on the link at the top right when you are logged in to the RIPE Atlas website, or go directly to: https://atlas.ripe.net/atlas/udm.html Currently, you can schedule two simultaneous measurements to the targets of your choice, from up to 10 probes. You can specify parameters like the area of the probes, IPv4 or IPv6, timing of the measurement, and type (currently ping or traceroute). And you need to have sufficient amount of credits! For the time being, we have created a fairly low rate limit, which we expect to increase over time. More information about limits, credits and other aspects of the UDM system can be found in the documentation: https://atlas.ripe.net/doc/udm Discussion and questions about UDM can be directed to the Atlas mailing list (ripe-atlas(a)ripe.net) You may also be interested in joining us at the UDM "Birds of a Feather" (BoF) session at RIPE 64 in Ljubljana, on Thursday, 19 April after the Measurements, Analysis and Tools (MAT) Working Group session. https://ripe64.ripe.net/programme/meeting-plan/bof/ Happy measuring! - The RIPE Atlas team ps We have also published a RIPE Labs article about UDM launch: https://labs.ripe.net/Members/becha/ripe-atlas-user-defined-measurements-ar…

Announcement of next RIPEstat demo now on RIPE Labs
by Mirjam Kuehne 10 Apr '12

10 Apr '12

Dear colleagues, The next RIPEstat demo will be presented live at RIPE 64 in Ljubljana on Monday, 16 April at 18:15 in White Hall (side room). After the demonstration there will be time to discuss RIPEstat development with other interested people. Please find more details on RIPE Labs: https://labs.ripe.net/Members/cteusche/ripestat-demo-s2e04 Topics for the demo include ranges, widgetisation, the RIPE Database Object Browser widget, and the Hierarchy Browser widget. If you're not able to attend the demo, there are other opportunities to meet the people behind RIPEstat and to watch a recording of the demo (see details in the article on RIPE Labs). Kind regards, Mirjam Kuehne RIPE NCC

New on RIPE Labs: Latest RIPEstat Demo report
by Mirjam Kuehne 20 Mar '12

20 Mar '12

Dear colleagues, Please find the report of the latest RIPEstat demo session on RIPE Labs: https://labs.ripe.net/Members/cteusche/ripestat-demo-s2e03 The third RIPEstat demo for 2012 covered all the new and modified widgets that were added in the last month: ASN Neighbours, Geolocation History, Prefix Count, Prefix Size Distribution, Routing History, and Announced Prefixes. Other new features included enabling the RIPE NCC Access login system, and links to RIPEstat from the RIPE database. It's also time for us to evaluate our demo format, so please take a moment to give us your feedback about what you like about our demos, and what you want changed. Kind Regards, Mirjam Kuehne RIPE NCC

virtual map of Internet on the basis of RIPE ATLAS data
by Andrei Sukhov 09 Mar '12

09 Mar '12

Dear Sirs, I am Andrei Sukhov from Samara. I would like to discuss the construction of virtual map of Internet on the basis of RIPE ATLAS data. Virtual map of the Internet Introduction Recently, numerous measuring systems like RIPE ATLAS are established to monitor the global network, organization of inter-domain routing principles and concepts of connectedness. As a rule, measurement mechanisms are based on modifications of the time-tested tools: ping and traceroute. That is, measure the round-trip time of package and the way as a sequence of routers that handle packets. In order to visualize the resulting pattern geographic maps are used with the coordinates of boxes. This picture doesn’t reflect the structure of the network. More recently, a new approach for the representation of network infrastructure is appeared in sensor networks in [1-3]. Virtual coordinate systems are designed to find the shortest route based solely on intranet information. The network selected a few points, called anchors, the number of network hops is found from these anchors to each box. This number is taken as the location of this point relative to the anchor base. Vectors defining the position of a point relative to this basis are non-negative coordinates, which makes it difficult to build the map. Special virtual conversion allows us to set the direction and pick axes. After that, each point receives a normal position on the map. Depending on the number of selected anchors we can build two-and three-dimensional maps. The building procedure Virtual maps can be constructed to render the most important Internet services, primarily for access to DNS servers and point of traffic exchange (Amsterdam-IX, for example). To do this, we need to select the four key DNS servers as anchors, with the help of a RIPE ATLAS system to measure the number of hops from different boxes to the selected points. Thus, we obtain the original data on the structure of the network. After converting the virtual coordinate system, we calculate the conventional two-dimensional coordinate and construct the corresponding 2D maps. For locations of points can be seen on the availability of new servers, remote seals show the desired location for the mirror. It seems to me important to start a discussion about what the servers selected as anchors and how to make measurements to the traceroute command issued a number of transitions to the anchors. Can you set up a RIPE ATLAS system now that it had the necessary measurements? 1. J.N. Al-Karaki, and A.E.
