ANNOUNCEMENT: RIPE NCC's New Projects Proudly Presents New RIS Features
by Matthew Williams 06 Sep '02

06 Sep '02

[Apologies for duplicate emails] Dear All, RIPE NCC are pleased to announce the following RIS features: ============================================= * New Plots added to the RISreport The RISreport creates plots on a daily basis by using data from the RIS database. The new plots are generated per RRC and for the RIS as a whole: 1. AS number distribution -Origin-only ASes: ASes only seen to the right of AS paths -Transit ASes: ASes not seen exclusively to right of AS paths -Private: ASes designated for private use (64512 - 65534) -Other: ASes in ranges held or reserved by IANA or designated for experimental use 2. Average AS path length -Mean -Standard Deviation -Ratio (Mean/Standard Deviation) 3. Distribution of AS path length URL: http://www.ris.ripe.net/risreport/ (Click on "Totals" for each RRC or "All RRC boxes" at the bottom of the page) -------------------------------- * "RIS Martians" We provide now daily lists of Martians seen by RIS. We use the prefixes listed in Bill Manning's Internet Draft: "Documenting Special Use IPv4 Address Blocks that have been registered with IANA" (http://www.isi.edu/~bmanning/dsua.html) for our definition of Martians. URL: http://www.ris.ripe.net/martians/ -------------------------------- * "BGP Traffic Hot Spots" by the RIS These are daily lists of prefixes for which high BGP announcement or withdrawal activity has been observed by our Remote Route Collectors (RRC). We provide the lists per RRC and for the entire RIS. This is a list you don't want to be on ;) URL: http://www.ris.ripe.net/topten/ -------------------------------- * RIS Prefix Statistics Monthly lists of the number of prefixes seen by each RRC and the entire RIS. URL: http://www.ris.ripe.net/prefix-stat/ -------------------------------- * Addition to the RIS Help Pages: "BGP Cheat Sheet" Current Sections: -The Community Attribute -Brief Overview of BGP Routing Instability -Route Flap Damping/Dampening Please send your comments and suggestions to ris(a)ripe.net. More topics will be added later. URL: http://www.ripe.net/ris/bgpcheat.html ================================ For more information about the RIS: http://www.ripe.net/ris/ Best regards, The RIS team: James Aldridge, Daniel Karrenberg, Henk Uijterwaal, Arife Vural and Matthew Williams --- > Matthew Williams-Bywater (MW243-RIPE) > Customer Liaison Engineer > RIPE NCC (www.ripe.net)

ANNOUNCEMENT: RIPE NCC New Projects' Activities during RIPE 43
by Matthew Williams 03 Sep '02

03 Sep '02

[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)

FYI: CIDR Report changes
by Philip Smith 26 Aug '02

26 Aug '02

Hi, As most of you know, the CIDR Report was conceived by Tony Bates in 1995 as a means to monitor and inform the community about the amount of CIDRisation activities being carried out by Internet Service Providers. The CIDR Report has been highly successful, much referred to and well respected snapshot of the growth in the Routing Table, as well as providing information on the level of aggregation being carried out in our community. In recent years it has become more of a challenge to maintain the software to keep up with the rapid growth in the Internet. Philip Smith, who has produced a widely published Routing Table Report since late 1998, has helped to keep the Report up to date with current allocation and assignment information. But with the large number of views of the routing table, and with the numerous requests many individuals and organisations have been making for enhancements to the CIDR Report, we have agreed that the future of the CIDR Report now rests alongside the very comprehensive BGP Table Analysis which Geoff Huston has been running for the last year. This Friday's CIDR Report (23rd August) was the last one posted from Tony's original system. As from the coming Friday (30th August), the CIDR Report will come from Geoff Huston's new implementation. The e-mail will go to the same operations mailing lists, will look very similar in layout, and will have greatly updated information compared with the original. Furthermore, the routing table view will be the summary from the RouteViews project. The supporting website for the CIDR Report has been vastly improved, with greater detail, the ability to search on aggregation effort per AS, and so on. A snapshot of Geoff's implementation can be found at http://bgp.potaroo.net/cidr/. Regular users of the information contained in the CIDR Report should check out the website and the new features in the report. As ever, comments and feedback are most welcome; these should be sent to <cidr-report(a)potaroo.net>. Tony Bates, Geoff Huston, Philip Smith

The Cidr Report
by CIDR Report 24 Aug '02

24 Aug '02

This is an auto-generated mail on Fri Aug 23 23:00:00 PDT 2002 It is not checked before it leaves my workstation. However, hopefully you will find this report interesting and will take the time to look through this to see if you can improve the amount of aggregation you perform. Check http://www.employees.org/~tbates/cidr-report.html for a daily update of this report. NEW: Check http://www.employees.org/~tbates/cidr-report-region.html for the regional version of this report. NEW: Check http://www.employees.org/~tbates/autnums.html for a complete list of autonomous system number to name mappings as used by the CIDR-Report. The report is split into sections: 0) General Status List the route table history for the last week, list any possibly bogus routes seen and give some status on ASes. 1) Gains by aggregating at the origin AS level This lists the "Top 30" players who if they decided to aggregate their announced classful prefixes at the origin AS level could make a significant difference in the reduction of the current size of the Internet routing table. This calculation does not take into account the inclusion of holes when forming an aggregate so it is possible even larger reduction should be possible. 2) Weekly Delta A summary of the last weeks changes in terms of withdrawn and added routes. Please note that this is only a snapshot but does give some indication of ASes participating in CIDR. Clearly, it is generally a good thing to see a large amount of withdrawls. 3) Interesting aggregates Interesting here means not an aggregate made as a set of classful routes. Thanks to GX Networks for giving me access to their routing tables once a day.
