Hi,

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 comment.



This memo describes a mobile communications use case for congestion exposure
(ConEx) with a particular
 focus on those mobile communication networks that are architecturally similar
 to the 3GPP Evolved Packet System (EPS).



I have the following comments:

l



1. It should be helpful to consider the communication security between the
ConEx senders and receivers such as the Confidentiality, data integrity
 and peer entity authentication in the security considerations part. Because in
 general, the corresponding risks are still possible to exist.

l



2. The authentication mechanism among all the elements of ConEx solution should
also be considered to handle the condition of faked messages or invalid
 peer elements.



Recommendation:  Ready With Issues



B.R.
