The Cidr Report

03 Nov '00

This is an auto-generated mail on Fri Nov 3 12:00:00 PST 2000 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. 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is possible even larger reduction should be possible. 2) Weekly Delta A summary of the last weeks changes in terms of withdrawn and added routes.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 amont of withdrawls. 3) Interesting aggregates Interesting here means not an aggregate made as a set of classful routes. Thanks to xara.net for giving me access to their routing tables once a day. Please send any comments about this report directly to me.

Dear Kurt, you answered to Shane: > > I've been looking over the 'advisory' attribute, mostly in preparation > > for the upcoming RIPE-181 to RPSL conversion (RPSL does not have this > > attribute). > > I'm not sure if this field is anyway obsolete right now. You are right - the advisory attribute *is* obsolete - so no need to further look into it, Shane. I definitely do not want to see it replicated into RPSL ;-) Thanks Joachim --- JS395-RIPE -- standard disclaimer ---

As promised. http://uk.geocities.com/maff2k/multi.doc Apologies for the microsoft format! I'm putting the html bit together at the moment. Please note this is 'work in progress' there is a better than slim chance that I've missed something fundamental which would mean that this won't work. Constructive critisism only please! Kind regards Matthew

The Cidr Report

This is an auto-generated mail on Fri Oct 20 12:00:00 PDT 2000 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. 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 amont of withdrawls. 3) Interesting aggregates Interesting here means not an aggregate made as a set of classful routes.

PAM2001 Call For Papers (fwd)
by Henk Uijterwaal (RIPE-NCC) 17 Oct '00

17 Oct '00

Passive & Active Measurement: PAM-2001 Second call for papers A workshop on passive and active measurement techniques for high speed computer networks and the Internet Amsterdam, the Netherlands, April 23-24, 2001 Program Committee: Henk Uijterwaal RIPE-NCC, NL, Conference Chair Nevil Brownlee U.Auckland, NZ Randy Bush Verio, USA kc Claffy CAIDA, USA Les Cottrell SLAC, USA Geoff Huston Telstra, AU Daniel Karrenberg RIPE-NCC, NL Ian Graham U.Waikato, NZ Yasuichi Kitamura APAN, Japan Will Leland Telcordia, USA Tony McGregor U.Waikato, NZ Ronn Ritke NLANR, USA Rick Whitner Agilent, USA As the Internet has grown over the last decade the need for precise measurement of network traffic has become steadily more apparent; most of today's Internet Service Providers and many of their large network customers are collecting and analysing traffic data for the purposes of performance monitoring, network engineering and cost recovery, but the engineering quality of these measurements vary. A steadily growing number of research groups have been working in the areas of: - Active Measurements, i.e. sending test packets and observing their progress through the Internet, - Passive Measurements, i.e. observing actual traffic on 'live' networks, - Performance Metrics, i.e. developing measures or indicators which can be used to characterise traffic behavior, - Traffic Statistics, i.e. attempting to understand and develop models of 'real' Internet traffic, and - Visualisation, i.e. finding effective ways to display what's happening in a network. After the successful workshop PAM2000 in Hamilton, New Zealand, in April 2000, the RIPE NCC will be organising another workshop on this topic in Amsterdam in April 2001. Papers are invited from the research, provider and any other communities on topics in the areas above, or any other area of network traffic measurement. Areas of interest include, but are not limited to: 1. 'Experience' papers, which describe practical uses of measurements, especially in large networks. 2. Papers on modelling network traffic, in particular if they are backed up by measurements of real traffic. 3. Papers describing network research that can be applied to existing networks. Extended abstracts (about 500 words, plain ASCII preferred) must be submitted by e-mail to pam2001(a)ripe.net by 12 November 2000. Paper submissions must contain the following: paper title, full name(s) of the author(s), organisational affiliation(s) and 1 email address where the author(s) can be contacted. Abstracts will be reviewed and acceptance notified no later than 18 December 2001. Papers, maximum 15 printed pages, must be submitted electronically by 5 March 2001. Details of acceptable paper formats will be published on the conference web site, http://www.ripe.net/pam2001 There will be an opportunity for participants to present measurement equipment and software. Proposals for demonstrations (about 500 words, plain ASCII) should be sent by email to the conference chair at pam2001(a)ripe.net by 5 March 2001. The program committee is investigating the possibility of organising one or more tutorial sessions in conjunction with the conference. Proposals for tutorials (about 500 words, plain ASCII) should be sent by email to the conference chair by 12 November 2000. The workshop will be held at the Barbizon Golden Tulip hotel in Amsterdam. Special room rates will be available for the conference. The conference fee will be (approximately) 175 Euro (US$165). The exact conference fee and details on registration will be published on the workshop's web page late November. The conference fee will include a printed copy of the papers selected for presentation at the workshop. Papers selected for publication will also be published on the web. Important dates: * 12 November 2000: Deadline for abstracts * 18 December 2000: Notification of acceptance * 5 March 2001: Final papers due * 23-24 April 2001: Conference Contact information: * PAM 2001 c/o RIPE-NCC Singel 258 1016 AB Amsterdam The Netherlands * Phone: +31.20.5354444 * Fax: +31.20.5354445 * Email: pam2001(a)ripe.net * Webpage: http://www.ripe.net/pam2001 ------------------------------------------------------------------------------ Henk Uijterwaal Email: henk.uijterwaal(a)ripe.net RIPE Network Coordination Centre WWW: http://www.ripe.net/home/henk Singel 258 Phone: +31.20.535-4414, Fax -4445 1016 AB Amsterdam Home: +31.20.4195305 The Netherlands Mobile: +31.6.55861746 ------------------------------------------------------------------------------ A man can take a train and never reach his destination.
