DISCUSS:
----------------------------------------------------------------------

Hi,

Thanks for this document.  I've balloted "discuss" on this document because I
would like to have a discussion with the responsible AD and other ADs as to
whether Standards Track is the right classification for this document based on
the text below, where it seems like a key part of the solution is only
experimental.  I appreciate that this document is also defining new TLVs, but
the pertinent IANA registry policy is only specification required, and there is
also reserved IANA values for experimental TLVs that could also be used, if
appropriate.

(1) p 7, sec 4.  RTT-based route selection

   In this section, we describe an algorithm that integrates smoothing
   and hysteresis and has been shown to behave well both in simulation
   and experimentally over the Internet [DELAY-BASED].  While
   implementations MAY use this algorithm, it is considered
   experimental, since we do not currently have a theoretical
   understanding of its behaviour, and in particular we do not know by
   how much it could be simplified without impairing its functionality.

Regards,
Rob
