Hi Sri, I thumbed through the document, but will do a more careful read and get back to you. One aspect that the two proposals have in common is the use of an internal instance of BGP to keep track of mobile network prefixes while advertising only one or a few aggregated network prefixes to the outside world. AERO (and its predecessor IRON) have been doing that for a long time, having learned the lessons from the Connexion-By-Boeing experience.
