Dear Administrator, Please forgive us any crossposting of this message. If you are not the person responsible for WWW caching at your institution, please pass this on to whoever you think would be appropriate. Thank you. Enclosed you can find a survey form on operational caching systems in Europe. The survey is conducted by the Interdisciplinary Centre for Mathematical and Computational Modelling, Warsaw University which is hosting the Polish national caching project. By taking part in this survey, you will help to produce a more reliable and efficient caching infrastructure for Europe. This survey is regarded as a contribution to the European caching task force (for details about this initiative please refer to http://www.terena.nl/tech/projects/choc/) If this is feasible, we would ask you to fill out the online version of the survey, that is available at http://w3cache.icm.edu.pl/survey/ rather than responding by email, since this would greatly facilitate our gathering the results. Otherwise, send your answers to survey(a)icm.edu.pl. If you consider any questions to be sensitive or difficult to answer, feel free to skip them. Results of the survey will be published at http://w3cache.icm.edu.pl/survey/results/ Thank you very much for your time, John Martin Wojtek Sylwestrzak --SURVEY STARTS HERE-- ### Section 1 - General questions 1.1 Primary contact information First name : Last name : Title : Institution : E-mail : Street address : City : Code : Country : 1.2 Your hosting institution is a: [ ] College/high school [ ] University/research institute [ ] Governmental institution [ ] Internet service provider [ ] Other commercial [ ] Other, please specify: 1.3 What is the URL of your service ? 1.4 Would you like your service to be added to a public list of caches for your region ?

Hostcount for August 1996
by Mirjam Kuehne 05 Sep '96

05 Sep '96

Dear all, Here is the hostcount for August 1996. The table shows an increase since last month of more than 86,000 (or 2.9%) to a total of over 3,110,000 hosts in the DNS in Europe. DE shows the highest increase for August with more than 24,000 hosts more than in July. In some countries we see quite a significant decrease this month, also in countries were the hostcount is done remotely. We couldn't find any explanation for this besides general connectivity problems and servers not responding. The hostcount can also be found under ftp://ftp.ripe.net/ripe/hostcount. The graphical version of the hostcount can be found at ftp://ftp.ripe.net/ripe/hostcount/RIPE-Hostcount-{Mo,Qu}.eps The translation of the country codes can be found at ftp://ftp.ripe.net/iso3166-countrycodes I would like to thank all people who help me to create the hostcount every month by counting hosts locally: at Gerhard Winkler <winkler(a)cc.univie.ac.at> be Herman Moons <Herman.Moons(a)CS.kuleuven.ac.be> ch Marcel Schneider <hostmaster(a)nic.ch> cy Panagiotis Tzounakis <pj(a)ics.forth.gr> cz Jiri Orsag <Jiri.Orsag(a)eunet.cz> de Peter Koch <pk(a)TechFak.Uni-Bielefeld.DE> dk Robert Martin-Legene <robert(a)dknet.dk> es Jose Sanchez-Seco <jose.sanchez(a)rediris.es> fi Petri Ojala <ojala(a)eunet.fi> fr Annie Renard <Annie.Renard(a)inria.fr> gr Dimitris Zisiadis <zisiadis(a)forthnet.gr> hr Ivan Maric <Ivan.Maric(a)stribor.srce.hr> hu Gabor Kiss <kissg(a)sztaki.hu> ie Mike Norris <mnorris(a)dalkey.hea.ie> il Sason Levi <sason(a)NetVision.net.il> it Antonio_Blasco Bonito <bonito(a)nis.garr.it> no Havard Eidnes <Havard.Eidnes(a)runit.sintef.no> pl Irek Neska <irek(a)nask.pl> pt Armando Domingues <fccn(a)dns.pt> ru Andrey Dobrotsvetov <adbr(a)ripn.net> sk Ivan Lescak <Ivan.Lescak(a)Slovakia.EU.net> Lubos Elias <Lubos.Elias(a)uakom.sk> sm Antonio_Blasco Bonito <bonito(a)nis.garr.it> tr Yener Yigit <yener(a)knidos.cc.metu.edu.tr> uk Kevin Hoadley <K.Hoadley(a)nosc.ja.net> If you have any questions, please don't hesitate to contact me.

New Document available: ripe-143
by RIPE NCC Document Annoucement Service 03 Sep '96

03 Sep '96

New/Revised RIPE Document Announcement -------------------------------------- A revised/new document is available from the RIPE document store. Ref: ripe-143 Title: Alternative Models for RIPE NCC Revenue & Charging 1997 Author: C. Orange, P. Ridley Date: 3 Sept 1996 Format: PS=288268 TXT=56127 bytes Obsoletes: Obsoleted by: Updates: Updated by: See also: ripe-134 Short content description ------------------------- This report describes the revenues that must be generated for operating the RIPE NCC in 1997. A number of alternative charging models are considered which can be used to generate the required revenues. These models are described in detail and the benefits and drawbacks of each are considered carefully, resulting in a recommendation for a charging model for 1997. This document provides input for the deliberations of the RIPE NCC contributors committee. The revenue figures and a particular charging model are expected to be decided at the contributors committee meeting on September 11th, 1996. After that meeting the revenue and charging model chosen will be described in a separate document, to be submitted to TERENA for formal endorsement as the charging mechanism to be implemented in 1997. This document will remain unchanged, providing documentation and background of the models researched. Those interested in the mathematical basis for the recommended model may want to acquire the postscript version (because the equations are readable). FTP Access ---------- All RIPE documents and Internet RFC`s are available via anonymous FTP from host ftp.ripe.net. Type "ftp ftp.ripe.net". Login with username "anonymous" supplying your email address as the password. After logging in, type "cd ripe/docs/" followed by the command "get filename". The relevant filenames for this document are: ripe-143.txt for the ASCII version ripe-143.ps for the PostScript version Electronic Mail Retrieval of Documents -------------------------------------- Documents can also be retrieved from the RIPE document store using a mail server program. For more information on how to use the program, send email to: mail-server(a)ripe.net with "send HELP" in the body text. RIPE NCC Interactive Information Server --------------------------------------- Type "telnet info.ripe.net". This is a menu driven service allows the document store to be browsed. After reading documents you are prompted as to whether you would like to receive an email copy of the document you have just read. If you would, you simply enter your email address and the document will be mailed to you. Below are details of alternative methods of access. Gopher Access ------------- The same documents are available via a "gopher" server at "gopher gopher.ripe.net". WAIS Access ----------- There is also a "WAIS" server at wais.ripe.net, where there is a WAIS index for RIPE documents "ripe-docs.src" WWW Access ---------- For those who wish to add this home page at the RIPE NCC to their own customized home pages, it can be accessed as: http://www.ripe.net MIME Mail Reader ---------------- Below is the data which will enable a MIME compliant Mail Reader implementation to automatically retrieve the RIPE document by FTP or mail server.

DIP and Multimedia Environments - Call for Papers
by R.B.Johnson＠bristol.ac.uk 02 Sep '96

02 Sep '96

***** Apologies if you receive this messages several times ***** Image and Vision Computing Journal Call for Papers DOCUMENT IMAGE PROCESSING AND MULTIMEDIA ENVIRONMENTS The Image and Vision Computing Journal announces a forthcoming special issue on Document Image Processing (DIP) and Multimedia Environments. Papers published in IVC have addressed a wide variety of image processing applications. This special issue will focus on DIP and related multimedia research, and will present a collection of high-quality papers on the subject. Document image processing is now an established field within the electronic imaging world. It is becoming even more prevalent wherever paper documents need to be transformed into electronic format for long-term storage, backup, multiple access and retrieval. The process of extracting information from often poor quality images of documents is a topic of active research. Multimedia research is still in its infancy but is a fast expanding area. Whilst the emergence of the World Wide Web has given a boost to the awareness of this phenomenon, there are a number of problems to be solved, not least the integration of DIP into multimedia applications. With the increasingly widespread use of multimedia to convey information in electronic form, where sound, moving images and graphics could be part of a compound document, the role of DIP becomes even more prominent. Thus a special issue on DIP and related multimedia research is a timely activity. Original high-quality contributions are solicited on all aspects of DIP and related multimedia applications. Emphasis will be placed on novel techniques, analytical methods, and design and optimization approaches rather than on specific software packages. Prospective authors are encouraged to submit contributions in the following areas or related subjects: o document decomposition strategies o OCR o form-based processing o compound document modelling and representation o compound document processing and analysis o compound document navigation and retrieval o fax recognition o DIP related standards o interfaces to DIP and multimedia environments o image and multimedia databases o network issues relating to image transmission o distributed or networked DIP and multimedia applications o security and encryption issues o business process re-engineering for DIP DIP and multimedia environments, as it is evolving, entails cooperation across corporate, educational and international boundaries. Thus preference will be given to papers that promote sharing of theory, techniques and experiences. Also papers that reflect a spirit of cooperation among multiple sources are encouraged. Authors are requested to submit three copies of their manuscripts to one of the Guest Editors listed below. IMPORTANT DATES 15th January 1997 Completed manuscript due for peer review. 15th March 1997 Acceptance notification. 15th June 1997 Final paper due. 3rd Quarter 1997 Publication of issue.
