WG,

There were no objections, so the chairs will prepare the write-up for this draft to send to the IESG in order to request publication.

Following the discussion in the working group session at IETF 97 in Seoul, this moves the text on how to use coupled congestion control with the Google congestion control (GCC) algorithm from the main text to an appendix, and makes the reference to GCC informative. The rest of the document is updated to use NADA as the example, rather than NADA and GCC. These changes are intended to prevent the coupled congestion control draft from blocking on a normative reference to GCC, since the GCC draft is not yet finished. They are not intended to change the scope of the work.

However, since there was some discussion around these changes in the meeting, the chairs would like to re-open the working group last call for an additional week to ensure there are no objections. If you object to the changes in this version of the draft, please comment to the list by 16 December 2016. If there are no objections, the chairs will prepare the write-up to send this to the IESG in early 2017.
