Does the AAA exchange run over IP? If so, what IP address is used? If not,
what packetization is used for the AAA exchange?

The AAA run over IP.

I understand that between the BS and the AAA server. But what about
the initial AAA exchange between the MS and the BS? At that time,
according to the draft, the MS has no IP address.

A PKM (Privacy Key Management) message is for initial AAA exchange at Figure 6 in the http://tools.ietf.org/wg/16ng/draft-sekim-16ng-ip-00.txt. More detailed procedures are on the section 6.3.2.3.9 in IEEE 802.16e-2005

OK - I think the draft should state that the MS-BS AAA exchange occurs
in 802.16 messages and not over IP.


I will appreciate to reply to [EMAIL PROTECTED]
This address ([EMAIL PROTECTED]) has some constraints to discuss.

No problem, but your KT address is used in the draft.

Thanks

Hi everyone,

   When initiating the connection, an MS is authenticated by the AAA
This is the first time that a connection mechanism is mentioned
in the draft. It seems to need more description or a reference.

An example of connection mechanism can be refer to
http://tools.ietf.org/wg/16ng/draft-sekim-16ng-ip-00.txt

If you (other author and reviewers) agree, I accept to merge above draft to draft-ietf-v6ops-802-16-deployment-scenarios-06.txt.

   server located at its service provider network.  All the parameters
   related to authentication (username, password and etc.) are forwarded
   by the BS to the AAA server.  The AAA server authenticates the MSs
   and when an MS is once authenticated and associated successfully with
   BS, IPv6 an address will be acquired by the MS through stateless
   autoconfiguration or DHCPv6.  Note the initiation and authentication
   process is the same as used in IPv4.

The AAA run over IP.
ASN gateway (or ACR that stands for Access Control Router) and AAA servers are network infrastructure.
ASN gateway is an WiMAX Forum's term.
Before an MS initiates to access, ACR and AAA maintain AAA connection by IP network. ACR serves for AAA client function and AAA servers provide AAA server function. It depends on AAA protocols such as RADIUS, TACACS and Diameter.
The WiMAX Forum prefer RADIUS protocol.
However the commercial service is used Diameter protocol in Korea due to its advanced capabilities.
