New work in the IETF that may be of interest to IEEE 802 groups.
Chairs forward to your groups if appropriate.

Subject: [New-work] WG Review: RADIUS Extensions (radext)
A new IETF working group has been proposed in the Operations and
Management Area.
The IESG has not made any determination as yet. The following
description was
submitted, and is provided for informational purposes only. Please send
your
comments to the IESG mailing list (iesg@ietf.org) by May 26th.
RADIUS Extensions (radext)
----------------------------------------
Current Staus: Proposed Working Group
Description of Working Group:
The RADIUS Extensions Working Group will focus on extensions to the
RADIUS protocol required to enable its use in applications such as IP
telephony and Local Area Network authentication, authorization and
accounting.
In order to ensure backward compatibility with existing RADIUS
implementations, as well as compatibility between RADIUS and Diameter,
the following restrictions are imposed on extensions considered by the
RADEXT
WG:
- All RADIUS work MUST be backward compatible with existing RADIUS RFCs,
including RFCs 2618-2621, 2865-2869, 3162, 3575, 3576, 3579, and
3580.
- All RADIUS work MUST be compatible with equivalent facilities in
Diameter. Where possible, new attributes should be defined so that
the same attribute can be used in both RADIUS and Diameter without
translation. In other cases a translation considerations
section should be included in the specification.
- No new RADIUS transports (e.g. TCP, SCTP) will be defined.
Work Items
The immediate goals of the RADEXT working group are to address the
following issues:
- RADIUS design guidelines. This document will provide guidelines
for design of RADIUS attributes, including discussion of the
appropriate use of RADIUS SDO-Specific Attributes (SSAs). This
document will also review RADIUS data types and associated
backwards compatibility issues.
- RADIUS implementation issues and fixes. This document will
address common RADIUS implementation issues and describe
proposed solutions.
- Revised NAI specification. This document, known as "RFC 2486bis"
will revise the NAI specification to correct known errors,
add support for privacy and internationalization, and provide
more details on routing.
- Pre-paid support. Prepaid services are contemplated in a number
of potential applications, including wireless LAN access and IP
telephony. In order to enable support of pre-paid services in an
interoperable way, the WG will provide definitions of the
attributes required to support operator service models for
pre-paid, as documented in liaison communications. This document
will
include within it a specification for interoperation with
Diameter Credit Control.
- SIP support. RADIUS is currently used for SIP authentication,
authorization and accounting. Standardization of these attributes
will enable improved interoperability.
This document will be upwards compatible with the Diameter SIP
application, and conform to existing IETF RFCs on HTTP Digest,
including RFC 2617, 3261, and 3310.
- LAN attributes. New attributes have been proposed to enable use of
authentication, authorization and accounting in wired and
wireless LANs. Standardization of these attributes will enable
improved interoperability.
- RADIUS MIB update. RFC 2618-2621 lack IPv6 compatibility, and modest
changes are required to address this issue. MIBs for RFC 3576 are
also needed.
