This position paper on how to incorporate Quality of Service into NDN or 
CCNx may be of interest to the NDN community.

Please send comments through the ICNRG list (icnrg at irtf.org) or 
privately to the author for posting to the list so this gets discussed 
in one public forum.

>    This is a position paper.  It documents the author's personal views
