Lets get started. Hopefully everyone is back from their biobreak or cookie hunting mission. This is a special routing and addressing plenary that the INT and RTG ADs asked the IESG to allocate. We felt that with the IAB workshop last year, the discussion in the San Diego plenary, and the significant interest on this topic implied that the community would like to discuss this topic. We will review where we are in terms of this problem and what activities have either been started or will be started in the IRTF and IETF on this. And at the end we'll open it up for comments and discussion. And we've asked Citizen Carpenter to hold a presentation that the ADs prepared together. Brian, welcome back on the stage.
