Re: AD comments on draft-ietf-rmt-pi-alc-revised-06

Magnus,

What I was suggesting as a standard RFC section a bit like "Security Considerations" in which the "Other domains" requirements should be collected, with guidelines as to what kind of thing should go in there. Then the rest of the document is unambiguously applicable to the Internet domain. Obviously the content of this section would be very dependent on the protocol being defined.

In a sense, this section would be the IETF doing the necessarily profiling for other standards groups itself (hopefully avoiding the risks you cite below). This happens anyway, but I'm suggesting we make it more explicit so that we do not keep repeating the argument about whether Internet domain requirements are MUST or SHOULD for protocols which have other domains of applications.

No, I don't think so. Because the variations are different for different
protocols. Sure, congestion control comes up pretty often. However, it
is generaly need also for none Internet usage. It is only when you both
reserve resources and ensure that the traffic provided over that
resource matches the reservation that you can be pretty certain that you
don't need congestion control. Even in these cases you commonly need to
deal with failure modes.

So, no even if reoccurring what goes into this often has variations and
special considerations.

Yes, for an SDO like DVB can clearly specify that you don't need to
implement congestion control because the traffic will always be ingress
filtered and shaped before being broadcasted. Thus congestion isn't a
real issue. However, I know that some IETFers do not like when other
SDOs profile our standards. There is a risk in profiling both from
interoperability and correct function.

Cheers
