In the paper, we specifically mentioned that we used RRC00's data and all the BGP sessions at RRC00 used multi-hop peering. So what we concluded is that data from multi-hop peerings should be carefully sanitized to remove those BGP updates associated with the instability of the monitoring session (in this case, it was the session instability caused by the worm attack).

About the BGP peering sessions.
by Shivani Joshi 16 Feb '05

16 Feb '05

Hi, I am a new member on this list. I had a question regarding the nature of the BGP peering sessions of the RRCs. Is there any place I can find accurate information about the way the different RRCs maintain their peering sessions; as in how many of the sessions are multi-hop BGP sessions and how many are direct link sessions etc? I was wondering about this since, there has been a paper (see below) published in 2002 that said that most of the RRCs peering sessions were multi-hop eBGP sessions and as a result the BGP data collected here cannnot be an accurate refelction of what goes on the actual Internet/backbone routers. "Observation and Analysis of BGP Behavior under Stress", Proceedings of the Second ACM SIGCOMM Internet Measurement Workshop (IMW '02), pp. 183-195, Nov. 2002 Any inputs that I can get regarding this will be very helpful. Shivani.

ANNOUNCEMENT: The RIS Project's Remote Route Collector is online at PAIX.
by rispeering＠ripe.net 11 Feb '05

11 Feb '05

[Apologies for duplicate mails] Dear Colleagues, We are pleased to announce that we have relocated the RIS Project's second North American Remote Route Collector at PAIX, Palo Alto. We are now ready to peer with PAIX members. We would like to thank Paul Vixie and ISC for their help. RRC14, has been operating since December 2004. It has an interface on the shared PAIX network and runs both IPv4 and IPv6. It collects routing information from all exchange members who peer with us. - Our peering addresses are: IPv4: 198.32.176.6 IPv6: 3ffe:80a::9 - Our AS number is: 12654 - Our policy: http://www.ripe.net/projects/ris/docs/rrc14.html The Routing Information Service (RIS) started as a RIPE NCC project in 1999. It has grown to over 300 IPv4 and IPv6 peers at twelve data collection points in Europe, Japan and North America. We collect and make available BGP routing information by devising tools that can help ISPs debug problems without being limited to a BGP view. We provide RIS raw data regarding the historical development of the Internet. If you want to peer with the RIS, please send an e-mail to <rispeering(a)ripe.net> or use the web form that you can find at: http://www.ris.ripe.net/peerreg.cgi You can find more information about RIS at: http://www.ripe.net/ris/ You can find RIS tools at: http://www.ripe.net/projects/ris/tools/index.html If you have any questions or comments, please send an e-mail to <ris(a)ripe.net>.
