Sending a pointer to what I mentioned at the mike on today's meeting: The group that works on the routing scalability problem at the IRTF is called Routing Research Group, or RRG. Their web page is here: http://www.irtf.org/charter?gtype=rg&group=rrg The mailing list is at rrg(a)psg.com. To subscribe, send mail to rrg-request(a)psg.com with the word "subscribe" in the body of your email. This is a quite active group already, but additional participation from the operator community would be very much appreciated. Jari
