2.  Architecture Topic - Evolution of the IP Model

Dave Thaler led a discussion on the Evolution of the IP Model.  
There is a current internet draft on this topic which lays out 
assumptions about the nature of the service model provided by IP to 
layers above it in the stack.  Dave had previously presented on 
this topic at IETF 72, and during this call the group walked 
through an updated version of that slide set.  The primary IAB 
effort on this topic over the last few weeks has been the 
consideration of these historical assumptions, with the goal of 
determining:

(1) the extent to which each assumption actually holds in practice 

(2) if guidance can be provided to the community as to the 
importance of upholding/strengthening a particular assumption, or 
(alternatively) if the assumption should be relaxed.  

The IAB intends to publish a guidance document on this topic in the 
coming months, and is also considering the subject for the IETF 73 
technical plenary.


3.  IETF Technical Plenary Planning

The IAB briefly discussed a plan for deciding on technical topics 
for future IETF plenaries.  Andy Malis volunteered to kick off a 
small planning committee to develop potential topics; Gregory, Loa, 
Lixia, and Barry agreed to assist in this 
effort.
