Hi,

Thanks a lot for all your comments (plus the nits we authors of the other 
-usage draft received offline).

I’ll try to address them all - but there are a two technical questions in this 
email that made me stop, so I’ll cut all the editorial stuff away and discuss 
them here - in line below:

Somehow the question seems irrelevant in the context of this draft, which is a 
list of transport features of protocols. These features are defined in the RFCs 
spec’ing the protocols - for SCTP, this is defined, and that’s why it’s here.

We can discuss this for the proposed services that a system should offer, which 
we try to write up in the minset draft:
I do think that an application should be allowed to assign a label to a TAPS 
flow (as we call them), which could then map to this function. I mean, isn’t a 
flow label supposed to identify a transport flow? Then a system-wide 
configuration wouldn't seem right to me.

But this doesn’t exist!  It’s strictly an IP function and I couldn’t find it 
described for UDP anywhere. I think we agreed on how a TAPS system should 
handle this, and this is reflected in
https://tools.ietf.org/html/draft-gjessing-taps-minset-04#section-6.4.1
… which may require a system to implement new local functionality, maybe based 
on this MTU function - but to my understanding it’s just not something that UDP 
offers.


Cheers,
Michael
