LAST REMINDER: Two More Days Until the Deadline for Inter-Domain Routing Workshop (IDRWS) Contributions
by Matthew Williams 26 Mar '04

26 Mar '04

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 [Apologies for duplicate mails] Dear All, The Inter-Domain Routing Workshop will take place at the RIPE NCC in Amsterdam during the weekend before RIPE 48 (May 1-2, 2004). This RIPE meeting will also be held in Amsterdam. The goal of the workshop is to bring together a focused group of operators, vendors, and researchers to discuss important mid- and long-term operational problems, as well as new academic ideas, in an OPEN forum. The wide scope for topics was intended on our part. Please remember to submit the abstract of your contribution for the workshop by March 28, 2004. See URL for more information: http://www.tm.uka.de/idrws/ Please feel free to drop us a line at idrws(a)ripe.net.

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."

Check Your Routing Table! Production Use of 84/8 Imminent.
by Daniel Karrenberg 11 Mar '04

11 Mar '04

The first allocation out of 84/8 has happened. It is *now* high time to check whether you see the pilot prefixes 84.192/16 and 84.255.248/21. If you do not see both of these prefixes it is extremely likely that you will have a connectivity problem very shortly. We also suggest that you check any packet filters you may be responsible for. Regards Daniel Karrenberg RIPE NCC ------ Notes: 84/8 has been allocated by the IANA on November 17th 2003, almost 4 months ago. The fact has been announced on this list a couple of times since. Routing decisions are fully within the responsibility of the network operators. The IANA and the RIRs will only announce which parts of the address space are currently in use. They have no authority whatsoever over routing decisions taken by you and other network operators. More details about the pilot prefixes can be found at http://www.ripe.net/ripe/draft-documents/deboganising-draft.html A visibility comparison of the pilot prefixes with some production prefixes can be found at http://www.ris.ripe.net/debogon/debogon.html Those interested in history, see http://www.ris.ripe.net/debogon/ More information on how to do Bogon filtering efficiently and reliably can be found at Team CYMRU: http://www.cymru.com/Bogons/index.html Unfortunately we are not currently able to provide a host within the pilot prefixes that can reliably answer pings, nor are we able to do connectivity checks from there. The allocation had to happen before we were ready with this part of the pilot prefix pilot.
