by Joao Damas 17 Aug '04

17 Aug '04

RIPE 49 is getting closer and in order to complete the agenda for the routing wg at the RIPE 49 meeting, taking place in Manchester, UK, 20-24 September, the chairs of the working group would like to request and invite presentation from members of the community on routing topics. Topics can range from operational experience at your networks that you would like to share, talks on routing protocol development and even specific vendor features that may be of interest to networks operators (particularly those not being marketing pitches). If you are interested in presenting or want to find out more about presenting at RIPE 49, contact either me or Joachim Schmitz, the 2 wg co-chairs. See you at RIPE 49 Joao Damas
