This document has been reviewed as part of the transport area review team's ongoing effort to review key IETF documents. These comments were written primarily for the transport area directors, but are copied to the document's authors and WG to allow them to address any issues raised and also to the IETF discussion list for information. When done at the time of IETF Last Call, the authors should consider this review as part of the last-call comments they receive. Please always CC tsv-art@ietf.org if you reply to or forward this review. This document is well-written and provides a good discussion of the topic. There are no additional transport-related concerns, e.g. all concerns are covered and discussed. I recommend to also forward the RG last call to ICCRG and maybe even tsvwg, for potential additional reviews but, more important, awareness. draft-singh-rmcat-adaptive-fec might be another draft to refer to (e.g. in section 4.3). I know this draft is expired and I assume the authors might be aware of it, but I found find it very relevant. However, that just my personal view.
