Hi Loa,

I have read the document and believe that the solution it describes is mature
and useful. I note that there is an IPR disclosure relating to
draft-mirsky-mpls-residence-time at that
might be assumed to also apply to this draft.  

My personal view is that we have a long tradition in this working group of
offering RAND terms that include the option of mutual non-assert. I think that
it is unfortunate that this is not the case for this document and would ideally
like to see that change or for the solution to be modified to avoid the patented
technology, however, in this case I think the material is sufficiently important
that we should proceed to publication.
