One more thing regarding 2): draft-4583bis also references RFC 8445 for ICE.

Hi,

>1) maintain the reference to RFC5389/STUN rather than replace it with a reference to RFC 8489

I support maintaining the reference to RFC5389, in order to align with other C238 cluster documents that reference STUN.

RFC5389 is also implicitly referenced via the ICE reference.

>2) make the reference to RFC 5389/STUN an informative reference as is already done for RFC 5245/ICE

My suggestion would actually be to update the ICE reference to RFC 8445. Again, that would align with other C238 cluster documents that reference ICE.

And, in RFC 8445 STUN is a *normative* reference.

Regards,

Christer

    I do note that the normative requirement is at SHOULD strength.

    However there are no statements that support an implementor to decide 
    under what conditions the requirement can be ignored, or the 
    consequences of ignoring, one or other of which should really be there.

    The lack of that information does not help in trying to evaluate the 
    consequences of updating the reference, versus leaving the reference as 
    it is - note that there is a risk both ways.

    The quick review I did, resulted in my feeling that the upgrade would be 
    OK, but I am not an expert in that area. Certainly I think either way it 
    should go to the WG for a quick review.
