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 summary of the review is READY. I am unqualified to weigh in on the heavy networking aspects of this draft, but I nevertheless found it approachable and understandable. My one minor editorial comment is that the section with parameters describes the effects, but never describes what the parameters are. Sincerely, Watson
