Summary:  This draft is ready for publication as a Informational RFC.


This document identifies scalability problems with modern flow-based
measurement, which are due to increasing traffic volume as well as
increasing measurement requirements complexity.  The document motivates
IPFIX mediation as a solution, and it gives a set of examples where this
solution applies.  The document also analyzes the disadvantages of IPFIX
mediation, which constitute the cost for better scalability.

I believe the document is ready for publication.  The document is easy
to read, concise, and well-structured.
