Hi,

During the call today, there was interest expressed in having a discussion on 
the
differences between AERO and Mobile IP. In the interest of getting the 
discussion
going, I will just say the following for now:

- the mobility archetype for Mobile IP is that of a mobile host that wanders 
away from
  its home link and tells a home agent on its home link where it has moved to

- the mobility archetype for AERO is that of a mobile router that stays 
connected to its
  home link even if it changes between access link technologies

The latter model is supported through the abstraction of an NBMA tunnel virtual
link that spans the mobile node's home network. IMHO, it is a cleaner and more
natural architecture that makes everything else easier.

Comments? Questions?

Thanks - Fred
