EOF, Amsterdam, May - Call for Presentations
by Daniel Karrenberg 25 Mar '04

25 Mar '04

[apologies for duplicates, hint: they have the same message-id] Hi Network Operations Folk, NOW is the time to consider making a presentation at the European Operators Forum (EOF) to be held during the 48th RIPE meeting in Amsterdam on Monday 3rd and Tuesday 4th of May 2004. We would like to have as many practical, hands-on presentations as possible this time. Remember: They do not have to be long. We prefer an stand-up interesting 10 minute presentation over a well prepared 90 minutes explanation of something not so interesting to operators. Find some information about presenting below and think about all those experiences this year that might be interesting to other operators. Should you have questions, please do not hesitate to contact me by e-mail at any time. Thanks Daniel -------------------------------------------------------------------------- Information about the EOF and presenting there: http://www.ripe.net/ripe/meetings/ripe-48/eof.html Information about the meeting in general: http://www.ripe.net/ripe/meetings/ripe-48/index.html -------------------------------------------------------------------------- Guidelines for submitting abstracts: We expect to finalise the program in shortly. We will get back to you then with scheduling details. In the meantime please provide the information below. We place special emphasis on the abstract which should contain references to related material already available if possible. Please send this to eof-coord at-sign ripe.net. - Author(s) - Speaker - (Working) Title - Abstract - Draft Presentation (if available) - Relation to other known work and/or presentations if known - Time Requested It would be helpful if the abstract was written such that potential attenders will learn what to expect from the presentation, i.e. "The presentation will describe our experiences with the Red Packet Washer (http://www.netdet.net/RPW/). We have been using the device for half a year now. It helps us deliver more hygienic datagrams to our customers and peers. We will discuss problems with packet discolouring as well as increased throughput to our upstreams due to decreased clogging by dirty micrograms. We will compare performance with the hand-scrubbing of packets which we used previously. Currently we are optimising device management and getting bugs resolved. We will strive to include the latest experiences in our report." is much better than "The presentation will describe the Red Packet Washer made by Network Detergents."
