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.



This is a Standard Track document that defines an RTP media streams

grouping mechanism in SDP.

The Security Consideration section clearly describes the potential attacks 

introduced by this new mechanism, and points out the general issue of SDP 

modification by untrusted entities, and potential issue with the buffering 

required by mechanism suggested by the draft.
