Hi Mike,
To avoid misunderstanding, the precondition of controlled domain may be kept as MUST. We can further specify that authentication MUST be used if, for specific scenarios, it is applied outside a controlled domain.

Regards,

Giuseppe

Why not just keep it at MUST so that you don’t pollute the internets.

We will end up having to filter for it anyway as always but it seems foolhardy and unpleasant to intentionally weaken the language.

Your new hotness belongs in your controlled domain. If you are going to try and force it onto networks you don’t control then it’s not going to work and you will end up having to tunnel it anyways.

Why is this so hard to understand?

Hi Erik,
Thanks for the input.
I tend to agree that the condition “MUST” can be changed to “SHOULD”. I can address your comments in the -08 version.

Regards,

Giuseppe

Giuseppe,

I think in S2.1 "MUST NOT" be used outside a "controlled domain" is perhaps a bit too strong.  Similarly in S6, "MUST be applied in...controlled domains" might be moderated down to "SHOULD only be applied...".

I'll note that it is possible for an AH option to be used to ensure the DstOpt variant is unmodified en route, and these two in conjunction can be used wherever desired to send such packets outside the given domain (subject, of course, to all the middlebox interference any such packet would inevitably receive -- but that's a separate issue).

A New Internet-Draft is available from the on-line Internet-Drafts directories.
This draft is a work item of the IPv6 Maintenance WG of the IETF.

        Title           : IPv6 Application of the Alternate Marking Method
        Authors         : Giuseppe Fioccola
                          Tianran Zhou
                          Mauro Cociglio

        Date            : 2021-06-22

Abstract:
   This document describes how the Alternate Marking Method can be used
   as a passive performance measurement tool in an IPv6 domain.  It
   defines a new Extension Header Option to encode Alternate Marking
   information in both the Hop-by-Hop Options Header and Destination
   Options Header.
