I am the assigned Gen-ART reviewer for draft-ietf-avtext-rtp-duplication-04
For background on Gen-ART, please see the FAQ at

Please resolve these comments along with any other Last Call comments
you may receive.
Summary: This draft is almost ready for publication as a Proposed
Standard but I have one issue that probably needs further clarification
in the draft.
* Section 7
I am not sure how the following MUST NOT is testable.
"First of all, RTP duplication MUST NOT be used
in cases where the primary cause of packet loss is congestion since
duplication can make congestion only worse."
I my understanding (correct me if I am wrong) neither the source of the
duplication nor the destination will know whether the packet loss was
due to congestion or something else. Can you please clarify how this
"MUST NOT" would be followed?
Thanks
Suresh
