Hi,

 

What aspect of FCFS is “First Come First Served With Expert Review” meant to 
capture?

 
If it’s just the idea that IANA will address requests as they come in (which 
may mean requesting clarification from the submitter rather than sending the 
request directly to the expert), that doesn’t need to be specified by the 
document.
 
If the idea is that the review should be extremely minimal, this should be 
described to the designated expert. 8126 recommends including guidance for the 
designated expert, and we often see this placed in its own (sometimes brief) 
subsection.
 
If the idea is that values will be assigned sequentially, this actually isn’t 
an FCFS requirement. RFC 8126 says, “IANA generally assigns the next 
in-sequence unallocated value, but other values may be requested and assigned 
if an extenuating circumstance exists.” 
 
If sequential assignment is mandatory, this should be stated in the document. 
If sequential assignment is expected but not mandatory, it could be mentioned 
to the designated expert. IANA will generally assign values sequentially unless 
asked to do otherwise.
 
We do object to “First Come First Served With Expert Review,” though, because 
“First Come First Served” as defined in RFC 8126 specifically means that there 
will be no expert review.
 
Thanks,
Amanda

Hello Michael,

 

Thanks for your quick reply and the proposed changes.

 

I will let the responsible AD sort out the publication status.

 

About IANA, I am unsure whether I have seen a FCFS registry with expert review, 
but happy to stand corrected.

 

Regards

Informational Seems wrong.

I see that the document declares that, and I think that's a copy'n'paste 
mistake.

It should be std.  At one point, we were told that only IETF-stream STD could

create certain categories of registry, and that's why we couldn't go ISE.

Fixed in my copy.

I'm not sure PCAP still has an expansion, but I've expanded it to "Packet

CAPture".  How about:

 

  This document describes a set of Packet CAPture (PCAP)-related LinkType 
values and

  creates an IANA registry for those values.

  These values are used by the PCAP and PCAP-Now-Generic specifications.

fixed.

So, we want FCFS with Expert Review.
