Hi, All:

I have read it and have the following comments.
1)  The document also specifies a method by which the SAP may send the
   identities of neighboring attachment points to the peer in the EAP-
   Initiate/Re-auth-Start message. 
[Richard] 
The are two kinds of CAP discovery model：The CAPs could be found by SAP or
by MH.
Why not specify both cases?

2) The peer sends an early-authentication request message (EAP-Initiate/
   Re-auth with the 'E' flag set) containing the keyName-NAI, the NAS-
   Identifier, rIK and sequence number.  
[Richard] 
The question is similar to the first one. It seemed that the text suggests
the CAP list must be offered by the SAP. 
In the real application , It is possible that: The CAP list offered by the
SAP is a reference or Mandatory.
Also, MH could have a CAP list by itself and may refer or use the CAP list
provided by the SAP. 
I suggest the draft would consider such cases and give some descriptions.

3)  This document only discusses the case of distributing the key to a
single CAP.
[Richard] it would let the draft only supports very limited scenarios. In
some cases like unstable Wireless signal, the MH have to rapidly 
Shift among several CAPs. In order to ensure the user experience, it is
possible that AAK is installed on the several 
CAPs before the MH's hand over.  

4) The realm in the keyName-NAI field is used to locate the peer's ERP/AAK
server
[Richard] what would happen if the SAP does not know the ERP/AAK server
indicated by the keyName-NAI

Regards
Richard

At the hokey WG session during IETF 81 last week, the beginning of a three
week Working Group Last Call for this document was announced.
However, it appears that no-one mentioned this fact on the mailing list :-(,
so the Last Call will be extended to 25 August.

A URL for this document is
http://www.ietf.org/id/draft-ietf-hokey-erp-aak-04.txt.  Please note that
the draft is only 15 pages long, including boilerplate, so reading it should
not be a major task.  Reply to this message with any comments (including
statements such as "I read it and it's fine").  Thank you.
