Harald, WG,

We apologize for the failure to inform and keep the WG aware of the
discussion and TSV ADs request to move draft-ietf-rtcweb-qos with it's
then content to TSVWG. A request chairs and authors accepted in the end
more than a year ago. This is clearly a failure by us chairs to ensure
sufficient transparency and a venue to timely protest that decision.

After reviewing this with TSVWG chairs, the non-recused RTCWEB chairs
(Magnus and Ted) do believe that the DSCP aspects require TSVWG action,
and that draft-dhesikan belongs there as a result. If there are aspects
of the QoS approach that are outside draft-dsheikan's current remit,
those might still belong in RTCWEB. We might also be able to pull some
pieces out of draft-dhesikan for local progress, but we can't take the
full document as it stands. Thus nothing prevents the WG from creating a
new QoS related WG document assuming a different scope than the previous
document. If any WG participants see a need for such a document they are
welcome to submit an individual document as a proposal for such a WG
document.

We note you protesting the lack of progress of draft-dhesikan in TSVWG,
and state that as one reason why this document should be in RTCWEB WG.
After reviewing mailing list discussion, meeting minutes and talking to
the TSVWG chairs, it appears that the main reason it hasn't been making
more progress have been the lack of an draft update to resolve the issue
raised in the Berlin TSVWG meeting. We have good hopes that the document
can make fair progress in TSVWG assuming author and RTCWEB participants
make timely contributions to the document.

Harald, does this provide a clear enough way forward or, do you wish to
continue your appeal?

Best Regards

Magnus Westerlund
Ted Hardie
