RE: Reflecting new-MAM/SAM definition in diff-te drafts

Jim,
  I think we still need some more discussion.  Please see
http://ops.ietf.org/lists/te-wg/te-wg.2003/msg00290.html
as a result of the complexity of the overbooking options.
Thanks, Wai Sum

So is there agreement now?

If so, what's the fallout?

I don't want to pull the reqt's out of IESG, and as stated in the list,
it 
isnt the place MAM is defined (sorry SAM, I think we have enough
bandwidth 
models).

Francois, can you re-propose changes for proto, RDM and MAM?

thanks,

Jim

btw... I also think LOMs are lots of complexity for little gain :)
