No data was lost, but the program generating the daily plots obviously stopped running. I've rebooted the machine and I'm now generating the plots for the past couple of days.

According to the information that we got from Motorola, this should not cause any problem, see http://www.mot.com/ACCES/GPS/gpsfaq.html#899: --- Will Oncore GPS receivers fail at the August 1999 GPS rollover? No, all Motorola Oncore GPS receivers are able to properly handle the August 1999 GPS rollover. Tests have been performed using sophisticated GPS satellite simulators to test the August 1999 rollover. --- Henk ------------------------------------------------------------------------------ Henk Uijterwaal Email: henk.uijterwaal at 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 ------------------------------------------------------------------------------ The Committee (...) was unable to reach a consensus that substantial merit was lacking.

Is there anything that I can do to > help? Yes, this is about the RIPE-NCC Test-Traffic measurement box (or test-box). Paul Thornton started installation, then left and handed it over to Maurizio, Maurizio started to work on it but I didn't hear from him for a while, which is why I sent a reminder. Basically the problem is this (but before digging into this, you might want to check if Maurizio has dumped this on somebody @linx): The box (ripe-tt.linx.net) will be used to measure delays in the Internet. It has a GPS antenna in order to sync it's internal clock. The antenna has to see some fraction of the sky. Paul thought of a suitable spot for the antenna, but in practice, it wasn't. I then agreed with Maurizio: ---- (Cut and paste from email) ---- The box seems to be working as it should but the antenna location is really bad. It sees some satellites but the signals are noisy and weak, and definitely not strong enough for the receiver to realize that it has been moved from Amsterdam to London. If you think that you have a better spot for the antenna, please try to put it there. ---- That's the last I heard. To get the ball rolling again, who, if anybody, @linx is working on this?

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 at 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 at 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.
