Hi,

We posted a new version of draft-ietf-6man-mtu-option to address issues raised during the w.g. last call, a review by Mark Smith, and feedback from IANA.  The changes are:

   *  Added Experiment Goals section.
   *  Added Implementation Status section.
   *  Updated the IANA Considerations section to point to this document
      and remove Temporary status.
   *  Clarifications and editorial changes based on review by Mark
      Smith.

Please review.  Links below.

> Abstract:
>   This document specifies a new Hop-by-Hop IPv6 option that is used to
>   record the minimum Path MTU along the forward path between a source
>   host to a destination host.  This collects a minimum Path MTU
>   recorded along the path to the destination.  The value can then be
>   communicated back to the source using the return Path MTU field in
>   the option.
> 
>   This Hop-by-Hop option is intended to be used in environments like
>   Data Centers and on paths between Data Centers, to allow them to
>   better take advantage of paths able to support a large Path MTU.  The
>   method could also be useful in other environments, including the
>   general Internet.
