The Cidr Report
by CIDR Report 19 Jan '02

19 Jan '02

This is an auto-generated mail on Fri Jan 18 23:00:00 PST 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is possible even larger reduction should be possible. 2) Weekly Delta A summary of the last weeks changes in terms of withdrawn and added routes.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 amont 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.

---------- Forwarded message ---------- Date: Wed, 9 Jan 2002 17:07:46 -0800 From: rick_whitner(a)agilent.com To: pam2002(a)labs.agilent.com Subject: PAM2002 Registration Opens [Our apologies if you receive multiple copies of this announcement.] Passive & Active Measurement: PAM 2002 REGISTRATION OPENS A workshop on passive and active measurement and analysis techniques for high speed computer networks and the Internet Fort Collins, Colorado, USA March 25-26, 2002 As the Internet has grown over the last decade the need for precise measurement of the network and its traffic load have become steadily more apparent; most of today's Internet Service Providers and many of their large network customers are collecting and analyzing measurement 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 characterize traffic behavior, - Traffic Statistics, i.e. attempting to understand and develop models of 'real' Internet traffic, and - Visualization, i.e. finding effective ways to display what's happening in a network. PAM 2002 is a two-day event focusing on research and practical applications of passive and active measurement and analysis techniques for high speed computer networks and the Internet. This third PAM workshop follows successful PAM workshops in Hamilton, New Zealand, in 2000 and Amsterdam, in 2001. Registration for this workshop has now been opened. The cost of the workshop is $275 (US) prior to March 1, and $300 (US) thereafter. Attendance will be limited. Last year's event sold out. To register, go to: http://www.labs.agilent.com/hosted/conferences/pam2002/registration/ Also available on the web-site are the preliminary program: http://www.labs.agilent.com/hosted/conferences/pam2002/program/index.htm general information on the workshop: http://www.labs.agilent.com/pam2002 hotel information: http://www.labs.agilent.com/hosted/conferences/pam2002/accommodations/index. htm and information about the Fort Collins area: http://www.labs.agilent.com/hosted/conferences/pam2002/area_info/ Rooms are available at the conference hotel. A limited number of rooms are available at a special rate, on a first-come basis. These rooms begin at $81 (US) for a single, $91 (US) for a double. Mention "PAM 2002" to receive the conference room rate. To reserve a room, call, fax or email the hotel. Contact details can be found on the web page. There are still opportunities 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 pam2002(a)labs.agilent.com by 4 February 2002.

The Cidr Report

05 Jan '02

This is an auto-generated mail on Fri Jan 4 23:00:01 PST 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 amont 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.
