Note:  This was a working meeting for two IAB architecture topics.  As
a result, not all IAB members participated in the discussion.


2.  IP Model Evolution

Dave Thaler led a discussion on the Evolution of the IP Model.  The
conversation focused on a set of assumptions about the service
provided by the IP layer to layers above it in the stack.  These
assumptions are stated or implied by various IETF documents, but
are not currently recorded in a single reference.  Furthermore,
some assumptions have evolved over time and may no longer hold in
the current Internet.  The IAB intends to document these
assumptions and assess their relevance to current and future IETF
work.


3.  IPv6 / Firewalls

Stuart Cheshire led a discussion on the value proposition of IPv6
and its relation to middle boxes like NATs and firewalls.  One of
the main benefits of IPv6 deployment is the opportunity to restore
end-to-end characteristics of the network that have been degraded
over time.  However, firewalls deployed according to the current
IPv4 paradigm are likely to endanger this benefit.  The group
discussed several overlapping issues in this space and will work
to clarify the scope of a possible IAB document on the topic.
