This incarnation of the AAA Working Group will focus on development of an IETF Standards track protocol, based on the DIAMETER submission.
In this process, it is to be understood that the IETF does not function as a rubber stamp. It is likely that the protocol will be changed significantly during the process of development.
The immediate goals of the AAA working group are to address the following issues:
- Clarity. The protocol documents should clearly describe the contents of typical messages and the requirements for interoperability.
- Error messages. The protocol should define categories of error messages, enabling implementations to respond correctly based on the category. The set of error messages should cover the full range of operational problems.
- Accounting. The accounting operational model should be described for each type of network access.
- IPv6. The protocol must include attributes in support for IPv6 network access and must be transportable over IPv6.
- Transport. The protocol should be transport independent and must define at least one mandatory-to-implement transport mapping. Other transport mappings may also be defined. All transport mappings must effectively support congestion control.
- Explicit proxy support. The protocol should offer explicit support for proxies, including support for automated message routing, route recording, and (where necessary) path hiding.
- RADIUS compatibility. The protocol should provide improved RADIUS backward compatibility in the case where only RADIUS attributes are used or where RADIUS proxies or servers exist in the path.
- Security. The protocol should define a lightweight data object security model that is implementable on NASes.
- Data model. The proposal should offer logical separation between the protocol and the data model and should support rich data types.
- MIBs. A MIB must be defined, supporting both IPv4 and IPv6 operation.

noneAAA WG Minutes: AAA WG met once at IETF 59. The status of the following WG drafts were presented: Diameter Network Access Server Application Diameter Extensible Authentication Protocol Application Diameter Mobile IP Application Diameter Credit Control Application Diameter SIP application The current status of the working group is that the Diameter NASREQ, Diameter EAP and Diameter Credit Control are in WG Last Call, and should be ready to be sent to the AD upon revision. John Loughney presented the current status of the Diameter NAS application. There are a few remaining issues open. If the author does not get suggested text how to clear the issues, the issues will be rejected. Pasi Eronen presented the current status of the Diameter EAP application. There are a few open issues. The chairs request that everyone review the document and send issues during WG last call. MIPv6 Application has 2 discusses from IESG review. The main open issue is the use of symetric keys. The authors discussed the issues with Russ Housley after the meeting & will write-up an explaination about why symetric keys are OK with this application. This should clear the DISCUSS. John Loughney presetned the Diameter Credit Control. Open issues can be found here: http://danforsberg.info:8080/draft -ietf-aaa-diameter-cc/index. After the WGLC is complete, the authors will update the doucment. Miquel Garcia presented the Diameter SIP application, and the open issues. The authors will update the document and it should be ready for WGLC afterwards. Miquel Garcia presented a short draft on the AAA URI. It was agreed that there is a bug in the Diameter Base Spec wrt to the AAA URI. This draft will update RFC3588. It was agreed to make this a WG draft. Jari Arkko presented RFC2486-bis (Network Access Identifier). The chairs & ADs should discuss what to do with this draft. In the meantime, it will be discussed on the AAA WG. With any luck, the WG may be able to wrap up before IETF 60.
