[routing-wg]Routing WG meeting at RIPE 55.
by Rob Evans 30 Aug '07

30 Aug '07

Good people, As autumn approaches, so the next RIPE meeting bears down on us like a barrel of beer rolling over a small matchstick model. We will be holding a meeting of the routing working group, in its usual slot after lunch on Thursday, and Joao, Joachim and myself are now soliciting presentations. If you've got a routing topic that you think others might be interested in, whether it relates to global routing issues or how things are done within your ISP, please let us know -- along with an idea of how much time you want. All the best, Rob, Joao, Joachim
