First, I still contend that you, as *transport AD* **AND** who injected herself inside the ports review process (unprecedented for a transport AD, FWIW) should know better, ESPECIALLY given the feedback that was provided *two months ago*.

That said...

As transport AD *and* deeply following the ports review process, that should have been much more obvious to *YOU*, of all people.

Please note that this is a much smaller document that RFC6335 and it does not specify any change to the procedures in RFC6335 (but only working within the defined procedures), as Brian also indicated in his reply.

Please review his reply. It short-circuits the process in 6335 and attempt to claim that the IESG alone makes the final decision. Given the IESG would be filing the request, the appeals process clearly should be handled by the IAB, per Sec 7 of RFC 5226 (again, why an AD who the Nomcom deemed qualified also for the IAB doesn’t know this is disconcerting). And - to be VERY clear - YOU should recuse yourself of involvement in that process whenever it happens, as it relates to this doc.

That’s not how RFC 6335, despite being led by members of the IESG at the time as well.

Yes, it does:

In Sec 1 it *incorrectly* claims that nothing can be done if the original assignee can’t be contacted. In specifying a procedure for that case, it de-facto updates RFC 6335 at least for the one-pass scrub of the system ports suggested by your doc.

In Sec 2, it *incorrectly* claims that the IESG would be requested to make a decision about its own requests (“if these actions…”) and fails to mention any oversight by the IAB. Per RFC 6335 and 5226, the appeal should fall to the IAB because the IESG is the requester of the action. The IESG should not rule on its own request (that is a conflict of interest).

In the following paragraph, it attempts to subvert the appeals in RFC 5226 that are cited in 6335 for changes, claims that if there is a disagreement the IESG is empowered to make a decision - which is at least implied as final. Again, this is not what RFC 6335 specifies - 6335 allows appeal to the IAB.

> It operates within the process as defined by RFC6335. The IESG discussed that it would be good to do this mass clean-up step instead of keep handling it on a case-by-case basis. The decision to write and publish this in an RFC has been taken in order to make this as much as possible transparent to the community and get broader input - which is what we are doing right now in last call.

Again, you keep saying “instead of keep handling it on a case-by-case basis”, but haven’t provided any evidence that this has become an onus to the IESG.

As I mentioned off-list (and you keep ignoring), then this doc should focus on the transfer of standards-track assignments, not system ports.

> Of course being in this situation doesn't break the Internet giving it's working right now but it can easily cause problems (and potential delays) in future. 

There are NO urgent problems of this nature. The port assignments are permanent; any claim to urgency is ridiculous and again *unsubstantiated* by this doc.

> [MK] All in all a lot of information in that registry is just outdated which does make the registry less valuable. So why not give it a try to clean that up (now)!?

As I have noted, no reason - except to note that WHY RIGHT NOW is also *no reason*.

That is *again* incorrect; RFC 6335 allows system port assignment by both IETF review and IESG approval, per RFC 5226.

IESG approval is just that.

However, only ports assigned through the IETF doc stream are required to have the IESG as assignee, per RFC 6335 Sec 8.1.1. That stream is defined in RFC 4884 Sec 5.2.2 as IETF WG doc or AD sponsored.

That leaves IESG approved docs, which include IRTF docs and independent stream submissions, as well as (frankly) IAB submissions.

Again, it’s useful to note that the port assignment process in 6335 DOES NOT REQUIRE an RFC at all. Other options include experimental RFCs, informational RFCs, or even an ID that never progresses to RFC.

Again - and again - it is disconcerting that I need to point this out to someone who is charged with overseeing the ports assignment process itself.

How can I look that up? Where is that list?

You yourself admit the ports database has outdated information - that includes the fact that many ports do not indicate the RFC that triggered three assignment.

So again you can give exactly ONE example of the urgent need to relieve the IESG of the burden of doing this case-by-case.

IMO you have failed to make the case of urgent need.

Yes, but not the way you claim above.

But again, if the issue is IESG burden of managing standards whose ports are not IESG assigned, then FOCUS ON THAT.

Ports assigned to standards-track RFCs.

You do, as described in detail above.

Given your INDIVIDUAL injection into the ports review process - adding yourself to the port review email list (again, unprecedented for AD oversight of the ports review process) - it remains highly disconcerting to see this explanation.

And in case there was any doubt, what exactly is RFC 6335 if not a process doc?
