FW: Last Call:<draft-betts-itu-oam-ach-code-point-03.txt>(Allocationof an Associated Channel Code Point for Use byITU-T Ethernetbased OAM) to Informational RFC

[Rui Costa <[e-mail]>]

I fail to understand the issue under discussion.	

Can't imagine IEEE denying to grant Ethertype 0x86DD. If, however, from absurd that had happened, would the world stop or would we take the same information from the IP header version field?	

Regards,	
Rui

Considering that the need for this code point is a result of the ITU
not fully complying with the IETF agreement, I cannot agree that we
should simply allocate a code point for whatever the ITU wants to do
in the future.

It seems the best of the options to allocate a code point (much better
than squatting) - but tie it to a stable reference.  If the ITU can't
provide a stable reference, then perhaps an RFC is the best way.
There are lots of folks with opinions on the best procedure, but I
certainly don't support the idea of not restricting the usage to what
is clearly defined.

Hello,
I still expect the author of draft-betts to answer my question...
	"Maybe you could clarify how the text in your draft can be improved to protect the use of the code point from future extensions beyond the purpose of the code point allocation?"
I am a bit disappointed to see that the author simply does not respond to the questions and proposed modifications he got on the list. 
If we want to productively move forward, it would be good to have the author responding to the questions and proposals. 
Best regards,
Nurit

Ross,
i am afraid that you missed the point. There will not be a final version since as written in draft-betts, all  ITU recommendations are subject to revisions, and the code point will also be used for future revisions of the document. New messages/protocols can be defined in future revisions of the recommendation and they will use the same code point that is allocated for the first version.
This is a real issue.
Regards,
Nurit

נושא: RE: Last Call:<draft-betts-itu-oam-ach-code-point-03.txt>(Allocationof an Associated Channel Code Point for Use byITU-T Ethernetbased OAM) to Informational RFC I agree that the allocation of a code point should be to a specific version of 8113.1,

<tp>
Why?

I can understand a new code point being required if there is a new and backwards incompatible format for the messages, but if the messages are extended in a forwards compatible manner, adding new TLV for example, or a new format of IF_ID, then why should we burn a new code point?

Would you say that we should have a dozen different port numbers for HTTP to reflect its evolution over time?  If not, why not?

Demanding that the ITU-T come back to us for a new round of negotiation when it is technically unnecessary seems to be placing an unnecessary barrier between the two SDOs.

and specifically should be to the final version that is approved by the ITU-T (assuming that a final version of 8113.1 will be approved by the ITU-T). This would imply that draft-betts-itu-oam-ach-code-point should contain a normative reference to the final approved version of 8113.1.

Given normal IETF processes, this implies that the final RFC resulting from draft-betts-itu-oam-ach-code-point could be published as soon as the final version of 8113.1 is approved (with the understanding that there will be a small normal delay between "approved" and "published" which gives time for coordination). Given that the final version of 8113.1 might need to reference the RFC resulting from draft-betts-itu-oam-ach-code-point, a bit of cooperation might be needed between editorial staff at the ITU and RFC editorial staff, but I don't see why this should be a problem (I am sure that they all have access to email).

I would like to support Nurit's comments below. In particular, in the past the ITU-T has expanded upon or changed the usage of IETF codepoint allocations, in some cases incompatibly with its original usage or definition. In the future, all codepoint allocations to the ITU-T should be tied to one specific, dated revision of their specification only. This is similar to the ITU-T's own processes, such as section 2.2.1 of Rec. A.5, which requires a version number and/or date for referenced outside documents in ITU-T recommendations.

Cheers,
Andy
