I have reviewed this document as part of the security directorate's ongoing effort to review all IETF documents being processed by the IESG. These comments were written primarily for the benefit of the security area directors. Document editors and WG chairs should treat these comments just like any other last call comments. The draft defines three RTCP XR block types for reporting loss, duplication and discard summary statistics independent from the RTP application that is used, augmenting the ones in RFC3611. The draft is well written and clear, and I have only minor comments/questions: * 1.1 Summary Statistics Metrics Since these are summary (as opposed to raw) statistics metrics, does that mean that the concerns wrt to confidentiality are somewhat alleviated? And if so, shouldn't that go in the security considerations? * 2.1 Standards language Picture Type It is not clear from the text what Picture Type means. Are you saying that the 2 choices for Picture Type are respectively Key Frame and Derived Frame? If so, please make that more clear. Picture Type also seems a bit of a misnomer, but I guess Frame Type has unwanted connotations as well * 7 Security Considerations See my remark on 1.1 Cheers, Klaas
