Hi Wes,

The issue raised isn't that there is an RTCWEB document gated on it, but
that shipping code does require this to be resolved.  The message you point
to above notes a core issue, which I assume is this:

That said, I think the interesting facet of this document is that
packets within the same flow (defined by 5-tuple of address-port
pairs and protocol number) are receiving different codepoints, and
the implications of that for a CC that may be on top of them need
to be delved into.


I think the authors may not have seen "interesting facet"
as a clear enough signal that they were blocked on this.
Can you restate this problem to them, so that they understand either
where in the document they should raise the issue or where there is
work they can reference
for incorporation?

You may want to include pointers on why having this situation,

versus multiple flows going between the same end points in

other contexts, is a problem.  I'm kind of concerned as well
that they will take the simple solution (use the most stringent

QoS), which is clear enough from a congestion control perspective

but bad from other perspectives.

regards,


Ted
