I completely agree with you David. This is an IP networking problem easily solved by a mixture of DNS and IP routing. We do not even need to worry about IP mobility, at the mobility rates we are talking here regular convergence would work. I would partition the network into a mixture of IGP and BGP just like the Internet. That allows you full scaling and the ability to apply policy between the ASs. Callsign migration time would be limited by the b/w of the links used, but I would be disappointed if it were over a second within an IGP. I originally thought that this would need routing protocol enhancements, but on thinking about it, from a network perspective it would work right out of the box. Stewart/G3YSX
