ANNOUNCEMENT: New tool (RIB-stat) is available from RIS.
by Arife Vural 12 Mar '04

12 Mar '04

Dear All, In collaboration with the Technical University of Munich, we are pleased to make available a new experimental tool, RIB-stat v. 1.0, on the RIS web site. This tool allows you to reconstruct the RIB table at any arbitrary point in time. It does so by taking the RIB dump closest to the desired time, then apply all BGP updates collected by the RIS up to the desired time retroactively. A possible application for this tool is to understand routing problems, with this tool one can reconstruct the RIB shortly before and after a routing problem started. By comparing the RIB's, one can find out which BGP update(s) triggered the problem. This tool is a prototype written in Perl. Depending on the number of BGP feeds, BGP activity and RRC, it can take 30 minutes to apply 8 hours of BGP updates to a RIB. We expect that it can be speeded up considerably by rewriting it in a compiled language. Before doing so, we would like to have some feedback on whether you consider a tool like this useful and expect to use it in daily operations. The code can be downloaded from http://www.ris.ripe.net/source/RIB-stat-1.0.tar.gz The file RIB-stat.pl contains the actual code, the file README an example on how to use it. Please send your feedback and comments to ris(a)ripe.net. Kind regards, RIS Team

ANNOUNCEMENT: The RIS Project's Second Remote Route Collector in North America Deployed at the NYIIX (RRC11)
by Matthew Williams 09 Mar '04

09 Mar '04

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 [Apologies for duplicate mails] Dear All, The RIPE NCC is pleased to announce that the RIS Project's second Remote Route Collector in North America, RRC11, is now ready to peer with members at the New York International Internet Exchange (NYIIX). The collector is our first outside of the RIPE region to accept IPv6 peering sessions. RRC11, operational since February 2004, is located at TELEHOUSE's NYIIX 25 Broadway facility and is the twelfth collector to be deployed by the RIS. The RRC has an interface on the shared NYIIX fabric, running both IPv4 and IPv6, and collects routing information from all exchange members willing to peer with us. Many thanks to Alexander Koch and Tiscali for helping us out with transit. Our details: - ------------ - - Peering addresses: 198.32.160.99 (IPv4); 2001:504:1:0:0:A501:2654:1 (IPv6) - - Autonomous system: 12654 - - Policy: http://www.ripe.net/ris/rrc11.html - - Peering requests: * Email: rispeering(a)ripe.net * Web form at URL: http://www.ris.ripe.net/cgi-bin/peerreg.cgi The RIS is also present at MAE-West in San Jose and we are currently looking for more peers there. - - Peering information: http://www.ripe.net/ris/rrc08.html The Routing Information Service (RIS), which started as a modest RIPE NCC project in 1999, has gradually grown to over 300 IPv4 and IPv6 peers at now twelve data collection points in Europe, Japan and North America. Our mission is to collect BGP routing information over a function of time and make it available to the Internet community. In essence, this means devising tools that can help ISPs debug problems over time without being limited to a BGP view, and providing RIS raw data regarding the Internet's historical development. RIS Info: http://www.ripe.net/ris/ RIS Tools: http://www.ripe.net/ris/query.html Please send your comments to ris(a)ripe.net.

REMINDER: Inter-Domain Routing Workshop, RIPE NCC, Amsterdam (May 1-2, 2004)
by Matthew Williams 27 Feb '04

27 Feb '04

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 [Apologies for duplicate mails] Dear All, The Inter-Domain Routing Workshop will take place at the RIPE NCC in Amsterdam during the weekend before RIPE 48 (May 1-2, 2004). This RIPE meeting will also be held in Amsterdam. The goal of the workshop is to bring together a focused group of operators, vendors, and researchers to discuss important mid- and long-term operational problems, as well as new academic ideas, in an OPEN forum. The wide scope for topics was intended on our part. The organisers are: * Intel Research * Universität Karlsruhe Institut für Telematik * Technische Universität München, Computer Science Department * RIPE NCC * Schlund+Partner AG, Karlsruhe See URL for more information: http://www.tm.uka.de/idrws/ We are hoping that these discussions will become an invigorating and lively affair. Please feel free to drop us a line at idrws(a)ripe.net. Kind regards, Matthew Williams --- > Matthew Williams (MW243-RIPE) > Customer Liaison Engineer > RIPE NCC - http://www.ripe.net/np/ -----BEGIN PGP SIGNATURE----- Version: PGP 7.0.4 iQA/AwUBQD9V5sHkFbJe+GdoEQJM9ACfYr/r7uErUN7VG8As7AFszid7LS0AnRzB /ieShHagijt6tCx7Q4wvA/O2 =NAT1 -----END PGP SIGNATURE-----

ANNOUNCEMENT: libbgpdump v. 1.4b Released
by Matthew Williams 23 Feb '04

23 Feb '04

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 [Apologies for duplicate emails] Dear All, Libbgpdump 1.4 beta is now available on the RIS web site. The previous release was 1.3.1. Notable changes include: - - Route_btoa Replacement Libbgpdump now includes a replacement for route_btoa called bgpdump. Bgpdump's output syntax is the same as that of route_btoa. Bgpdump also supports IPv6 on more platforms than route_btoa and provides error reporting of corrupt data and unknown attribute types. It also supports machine-readable output and allows the user to select which timestamp to use for RIB dumps. Bgpdump was contributed by Agilent labs. - - Better Error Handling The library now provides access to corrupt data and unknown attributes in dump files. Every record which cannot be decoded now results in a message being logged to syslog, and the library keeps track of how many records were dumped and how many were successfully decoded. - - Autoconf Support Libbgpdump should now build on many more platforms, including cygwin. IPv6 support is automatically enabled if the system supports it (except on Windows), and no longer depends on user defines. - - Miscellaneous Fixes - Fixed possible endianness issues on SPARC. - Fixed a crash when processing NOTIFICATION messages. Libbgpdump 1.4 can be downloaded at http://www.ris.ripe.net/source/ . Please send your bug reports to ris(a)ripe.net. Best regards, On behalf of the RIS team, Lorenzo Colitti -----BEGIN PGP SIGNATURE----- Version: PGP 7.0.4 iQA/AwUBQDptz8HkFbJe+GdoEQJFhACeJd2sgxLNUAES5RWT76TGeF75oCMAoJyw f11RSDh0bBknJcy10wsVQwTT =LBsM -----END PGP SIGNATURE-----

by Matthew Williams 29 Jan '04

29 Jan '04

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 [Apologies for duplicate mails] Dear All, The Inter-Domain Routing Workshop will take place at the RIPE NCC in Amsterdam during the weekend before RIPE 48 (May 1-2, 2004). This RIPE meeting will also be held in Amsterdam. The goal of the workshop is to bring together a small, focused group of operators, vendors, and researchers to discuss important mid- and long-term operational problems, measurement techniques, router features and network management tools in an open forum. We hope that these discussions will become invigorating and lively affairs. The organisers are: * Intel Research * Universität Karlsruhe Institut für Telematik * Technische Universität München, Computer Science Department * RIPE NCC * Schlund+Partner AG, Karlsruhe See URL for more information: http://www.tm.uka.de/idrws/ Please feel free to contact us at idrws(a)ripe.net.
