Hi all:

I have performed an Operations Directorate review of
   draft-ietf-mif-happy-eyeballs-extension-10

  "This memo proposes extensions to the Happy Eyeball's algorithm
   requirements defined in RFC6555 for use with the multiple
   provisioning domain architecture.  The Happy Eyeballs in MIF would
   make the selection process smoother by using connectivity tests over
   pre-filtered interfaces according to defined policy.  This would
   choose the best interface with an automatic fallback mechanism."

This draft is well-written and easy to follow.  I have one suggested
improvement: in section 4.1, I think that
  "Only download applications larger than 20Mb over WiFi"
would be better as
  "Download applications larger than 20Mb only over WiFi"

Interworking (with Happy Eyeball) is only covered briefly in section 6
(Implementation Framework), which suggests that "the simplest way to
implement the processes described in this document is within the
application itself."  For an Operator - who can't really specify what
Apps users may install, this seems unduly hopeful.  Operators
might, perhaps, publish a list of Apps that are known to implement
these extensions properly.

The Security Considerations section is minimal, simply referring
to two earlier RFCs.

Section 5 contains many typos, it would benefit from some copy
editing (rather than leaving that to the RFC Editors).

Overall, technically this draft seems sound, but it would benefit
from some improvements as mentioned above.

Cheers, Nevil
