-----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 small, focused group of operators, vendors, and researchers to discuss important mid- and long-term operational problems, measurement techniques, router features and network management tools in an open forum. We hope that these discussions will become invigorating and lively affairs. The organisers are: * Intel Research * Universität Karlsruhe Institut für Telematik * Technische Universität München, Computer Science Department * RIPE NCC * Schlund+Partner AG, Karlsruhe See URL for more information: http://www.tm.uka.de/idrws/ Please feel free to contact us at idrws(a)ripe.net.
