From matthew at ripe.net Tue Sep 3 19:33:30 2002 From: matthew at ripe.net (Matthew Williams) Date: Tue, 3 Sep 2002 19:33:30 +0200 Subject: ANNOUNCEMENT: RIPE NCC New Projects' Activities during RIPE 43 Message-ID: <008001c25370$0547a860$b50100c1@ripe.net> [Apologies for duplicate emails] Dear All, RIPE NCC New Projects are pleased to announce the following activities during RIPE 43: ----------------------------------------------------------------- * Demonstrations of Test Traffic Measurements (TTM) and Routing Information Service (RIS): RIS Demo Expert help available Thu: 10:30-11:00 Fri: 10:30-11:00 TTM Demo Expert help available Thu: 15:30-16:00 Fri: 10:30-11:00 Location: Please ask at the Information Desk. ---------------------------- * TALK: "A RIS-based System for the Visualization of the Routing Flaps" to be held on Tuesday, the 10th of September, 2002, during the Routing Working Group session. FlapViewer is a service that allows one to visually detect and analyze BGP routing instabilities, usually referred to as "flaps". The system will retrieve BGP routing announcements from the RIS and then produce graphics of involved autonomous systems and their peering relationships with the routing changes being shown as animations. Speaker: Maurizio Patrignani (University of Roma III) URL: http://www.dia.uniroma3.it/~lombardo/flapviewer/ ---------------------------- * TALK: "Observations on Redundant BGP Traffic and Flaps from the RIPE RIS Collectors" to be held on Tuesday, the 10th of September, 2002, during the Routing Working Group session. The objective of Agilent Labs' RIPE NCC data analysis project is to visualize and characterize Border Gateway Protocol (BGP4) behavior. The work is based on protocol traffic collected at exchange points around the world by RIPE NCC's RIS. The project has two tracks: daily analysis and long-term pattern discovery. Speaker: Alexander Tudor (Agilent Labs) URL: http://www.ris.ripe.net/agilent-labs/ ---------------------------- For more information about New Projects and our services: http://www.ripe.net/ripencc/pub-services/np/ Best regards, RIPE NCC New Projects --- > Matthew Williams-Bywater (MW243-RIPE) > Customer Liaison Engineer > RIPE NCC (www.ripe.net) From wilhelm at ripe.net Fri Sep 6 13:24:41 2002 From: wilhelm at ripe.net (Rene Wilhelm) Date: Fri, 06 Sep 2002 13:24:41 +0200 Subject: New TTM features Message-ID: <200209061124.g86BOfEs018938@birch.ripe.net> Dear Test-box Hosts, We are pleased to inform about some changes and new features which recently have been implemented on the TTM website: - traceroute database stores originating AS numbers The daily processing of collected traceroutes between the TTM boxes has been expanded to look up and store originating AS number for each IP hop. In the initial implementation we consult the Internet Routing Registry at whois.ripe.net, using the -a flag to search route objects in both the RIPE database and the databases mirrored by this server such as RADB. A next version will get the information from the data collected by the RIS project. The traceroute query at http://www.ripe.net/cgi-bin/ttm/routing shows the AS information in an additional column. Note that for some prefixes more than one originating AS is registered in the IRR (i.e. two or more matching route objects are returned); in those cases we list the various AS numbers separated by a / Not quite ready, but expected to be released shortly is the extension of the routing CGI with an option that condenses the observed IP traceroutes to traces in AS space. This will allow you to more easily spot big changes in routing, when BGP policies cause different AS paths to be followed. - more interaction with summary tables The Delay summaries which used to be presented as static HTML pages, are now handled by more dynamic CGI scripts, taking input from XML data files. As a result, there is much more user control over ordering the rows in the table and the criterium for marking cells 'worse' (red) or 'better' (green). The default behaviour, when accessing the summaries for a box via http://www.ripe.net/ttm/Plots/ , is to sort the table on 'marked cells' i.e. the boxes for which the measured percentiles and losses have changed significantly are listed at the top of the table. This allows you to quickly spot problematic network connections. Through the form at the top of the page, it is possible to change the ordering and coloring criteria; for example, ordering on Median value in descending order, will immediately show which boxes are furthest away from yours (in terms of network latencies). To ease importing the summary data in other applications, the table can also be retrieved in ASCII (CSV, comma seperated values) and XML format. - ASCII option in Plots-on-Demand Similarly to summary tables, the raw data and long term trends can also be retrieved in CSV format. To this end we have added an 'ASCII' option to the plots-on-demand CGI ( http://www.ripe.net/cgi-bin/ttm/plots-on-demand ) Note that this is primarily intended to get small subsets of the data from one box to another for a short period of time. Users interested in *all* data send/received by their box on specific dates, should contact tt-ops at ripe.net; we'll then prepare corresponding files in ROOT format. - detailed testbox location Through the http://www.ripe.net/ttm/Plots/gpsinfo.html page we have always reported exact coordinates of the various boxes, and offered maps on a world/region scale with markers at the testbox locations. For those interested in geography, we now take it one step further: clicking on a testbox location in http://www.ripe.net/ttm/Plots/locations.cgi will take you to a (external to RIPE NCC) page on the Mapquest server showing a small map at city scale, centered around the testbox location. Depending on the information available at Mapquest, one can subsequently zoom in upto a street level scale. Finally we'd like to remind you of a feature added and announced late June: - User-configurable measurements between TTM test-boxes (C & D Series testboxes only) This feature allows the users to have more control over measurement settings and generated traffic between their own and target test-boxes. A newly devised configuration page makes it easy to modify transmission rates of packets, packet sizes and targets for measurements. Afterwards, these settings will be propagated automatically to remote TTM test-boxes. We expect to add more parameters in the near future. Please see the following URLs: Configuration page on our demo box http://tt01.ripe.net:10259/ (click on "Configuration") Configuration Help http://tt01.ripe.net:10259/html/configurationhelp.html We hope you find these additions useful. Feedback is, as always, welcome either by e-mail to ttm at ripe.net or by contacting us in person during the RIPE 43 meeting next week.

From henk at ripe.net Thu Sep 12 13:02:48 2002 From: henk at ripe.net (Henk Uijterwaal (RIPE-NCC)) Date: Thu, 12 Sep 2002 13:02:48 +0200 (CEST) Subject: RIPE NCC Membership survey Message-ID: Dear TTM and RIS users, This message was sent to the RIPE NCC LIR members list 2 weeks ago and we just realized that not all TTM and RIS users are on this list, while your input is important too. Kind regards, Henk --- Forwarded message --- Dear members and stakeholders, You may be aware that the RIPE NCC recently announced that we have commissioned KPMG to independently carry out a member and stakeholder survey on our behalf to take place from 1 September to 1 November 2002. The aim of this survey is to gather information from RIPE NCC members and stakeholders to help the RIPE NCC plan and improve its services to the membership. We would therefore like to invite you to participate in this survey by filling out and returning the survey forms to KPMG by 31st October. All responses go directly to KPMG and the source or identity of any input to the survey will remain confidential. The full details regarding this project can be found on our web site at: http://www.ripe.net/survey2002 Here you will find the Members Survey form, the Stakeholder Survey form and information for respondents. John Earls from KPMG will be coordinating this project. He will attend the RIPE 43 Meeting in Rhodes and will be available to discuss the survey with you in further detail. During September and October, John will be visiting a number of cities in the RIPE NCC service region to talk face to face with randomly selected members and stakeholders. In each city he has also scheduled a late afternoon opportunity for an informal discussion open to all members of the RIPE NCC. These open forums will allow those who attend to raise issues that they believe should be considered in the RIPE NCC future planning process. The schedule of locations and dates for these meetings can also be found on our web site at: http://www.ripe.net/survey2002/locations.html We will be sending out additional information over the next few weeks. If you do not feel that you are the correct person from your organisation to respond to the survey, please forward this information to the appropriate colleague. The RIPE NCC is dedicated to serving the needs of all its members and the Internet Community. Your participation in this survey is therefore greatly valued.Thank you in advance for your support.
