(Apologies for any duplicate mails). ________________________________________________________________________ Passive & Active Measurement: PAM-2000 Call for papers A workshop on passive and active measurement techniques for high speed computer networks and the Internet University of Waikato, Hamilton, New Zealand April 3 and 4, 2000 Abstracts due: 15 November 1999 Full papers due: 15 February 2000 Conference Chair: Professor Ian Graham, University of Waikato Program Committee: Nevil Brownlee (chair) The University of Auckland, New Zealand Scott Bradner Harvard University, U.S.A. Hans-Werner Braun NLANR, U.S.A. Randy Bush Verio, U.S.A. John Cleary University of Waikato, New Zealand Geoff Huston Telstra, Australia Kitamura Yasuichi CRL/APAN, Japan Tracie Monk CAIDA, U.S.A. Alastair Reynolds Hewlett Packard, Scotland Matthew Robinson RIPE Test Traffic WG, U.K. Henk Uijterwaal RIPE NCC, Netherlands Matt Zekauskas Advanced Network & Services, U.S.A. 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 behaviour - Traffic Statistics, i.e. attempting to understand and develop models of 'real' Internet traffic - Visualisation, i.e. finding effective ways to display what's happening in a network One such group is the Waikato Applied Network Dynamics (WAND) group, based at Waikato University in New Zealand. The WAND group will be local host to a workshop to be held in New Zealand early in April 2000, following the IETF meeting in Adelaide. 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. Papers reporting practical experience of measurement and/or analysis are especially welcome, in particular: 1) 'Experience' papers, which talk about practical uses of measurement, especially in large networks are strongly encouraged. 2) Papers on modelling would also be very welcome, especially if they're backed by measurements of real traffic. 3) More 'academic' papers are fine too, but please emphasise the 'practical' side of the measurements. Extended abstracts (about 500 words) must be submitted by e-mail to pam2000(a)cs.waikato.ac.nz by 15 November 1999. Abstracts will be reviewed and acceptance notified by 15 December 1999 or earlier. Papers, maximum 15 printed pages, must be submitted electronically by 15 February 2000. Details of acceptable paper formats will be published on the conference web site, pam2000.cs.waikato.ac.nz. Equipment and software demonstrations are also welcomed. Proposals for demonstrations should be sent by email to the conference chair at pam2000(a)cs.waikato.ac.nz by 15 December 1999. Hamilton is a city of some 100,000 inhabitants, situated 100 kilometres (80 miles) south of New Zealand's largest city, Auckland. The weather in April (our fall in New Zealand) is usually still warm and not too wet. This workshop follows immediately after the 47th IETF meeting in Adelaide, Australia (March 27-31, 2000). Travel from Adelaide through Auckland to the US is possible with United, Air New Zealand and Quantas (and possibly other airlines). Local travel and tourism can be arranged through the workshop's travel agents in Hamilton; Calder and Lawson, http://www.cnl.co.nz. The workshop will be held at the Novotel Tainui in Hamilton. Special room rates are available for the conference, and the conference fee will be about $US 150 ($NZ 250). A paper copy of the workshop proceedings is included in the conference fee. For further information see http://www2.wave.co.nz/~novotel/hnindex.html The workshop's web page is http://pam2000.cs.waikato.ac.nz ________________________________________________________________________

The Cidr Report

This is an auto-generated mail on Fri Aug 20 12:00:00 PDT 1999 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.

The Cidr Report

This is an auto-generated mail on Fri Jul 16 12:00:00 PDT 1999 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.
