Hi,



I have reviewed draft-ietf-straw-b2bua-dtls-srtp-08 as part of the Operational
directorate's ongoing effort to review all IETF documents being processed by
the IESG.  These comments were written with the intent of improving the
operational
 aspects of the IETF drafts. Comments that are not addressed in last call may
 be included in AD reviews during the IESG review.  Document editors and WG
 chairs should treat these comments just like any other last call comments.



I believe the document is 'Ready' for publication.



The document describes the behavior of media plane B2BUAs when using an SRTP
security context set up with the DTLS protocol. The target audience is mainly
the implementers of B2BUAs, and although the document may be an interesting
reading
 for operators deploying B2BUAs, its content has no direct operational impact.
 Although not mentioned in this document I assume that aspects of operation and
 manageability of B2BUAs are dealt with in other WG documents which apply here
 as well.



I have seen a few editorial nits, but I do not believe that it’s the role of an
OPS-DIR review to raise them. The RFC Editor will certainly catch these and
more. I will just mention one observation about the title. The document deals
 with a subset of the B2BUAs – those who act on the media plane. Why does not
 the title mention this (insert ‘media’) to ease search and make the scope more
 clear?



Regards,



Dan
