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.

Overview:

Loosely, this document describes a way of pre-congestion notification
marking of packets that builds on the Explicit Congestion Notification
(RFC 3168). The marking is only carrying meaning within a given PCN
domain.

Comments:

With the caveat of not being an expert in the field this draft is
about, I find the document relatively straightforward to understand
and the Security Considerations section reasonably complete (although
it perhaps would have been useful to describe what problems that
possibly could occur should a party inject PCN-marked packets inside a
network?).

Editorial:

Maybe useful to add a brief early section providing definitions of
abbreviations?
