General question - I know that the WiMax forum is working on more things
than just IP over 802-16e (etc.). You mention, for example, AAA, in the
description. Are you looking at more than just running IP over 802.16e
or something more?

Subject: A New BoF [16ng BoF: IPv6 over IEEE 802.16(e) Networks]
Folks,
We would like to announce a BoF at the upcoming IETF, leading
to identify what limitations and considerations apply to IPv6
adoption over IEEE 802.16(e), and to propose available
solutions. A mailing list is set up at
16ng(_at_)eeca16(_dot_)sogang(_dot_)ac(_dot_)kr and a proposed description is
below.
==========================================
IPv6 over IEEE 802.16(e) Networks BoF (16ng)

DESCRIPTION:
Broadband Wireless Access Network addresses the inadequacies
of low bandwidth wireless communication for user requirements
such as high quality data/voice service, fast mobility, wide
coverage, etc. The IEEE 802.16 Working Group on Broadband
Wireless Access Standards develops standards and recommended
practices to support the development and deployment of
broadband Wireless Metropolitan Area Networks. In addition,
IEEE 802.16e supports mobility over IEEE 802.16 as an
amendment to the IEEE 802.16 specification.
Recently, much work is in progress by the WiMAX Forum. In
particular, its NWG (Network Working Group) is responsible for
the IEEE 802.16(e) network architecture (e.g., IPv4, IPv6,
Mobility, Interworking with different networks, AAA, etc). The
NWG is thus taking on work at layers above those defined by
the IEEE 802 standards (typically limited to the physical and
link layers only). Similarly, WiBro (Wireless Broadband) is a
Korean effort based on the IEEE 802.16e specification which
focuses on the 2.3 GHz spectrum band.
IEEE 802.16(e) is different from existing wireless access
technologies such as IEEE 802.11 or 3G. Accordingly, the use
of IP over an IEEE 802.16(e) link is currently undefined, and
will benefit from IETF input and specification. For example,
even though Neighbor Discovery has been specified to work over
point-to-point type links (e.g., as available in 3G), it
applies most naturally to link technologies capable of native
multicasing. Thus, it is not yet clear how it would work over
IEEE 802.16(e) networks. Even though these supports a PMP
(Point-to-Multipoint) mode, there is no provision for
multicasting IP packets, hindering the basic standard IPv6
operation. An IEEE 802.16(e) connection for IP packet transfer
is a point-to-point unidirectional mapping between medium
access control layers at the ubscriber station and the base
station. This eventually requires convergence protocols to
emulate the desired service on network entities such as base
stations, which may limit IPv6 features. As for fast mobility,
the characteristics of IEEE 802.16e link-layer operation may
require an amendment to the Fast Handover Mobile IPv6 scheme
(RFC 4068), something which may be pursued in the MIPSHOP WG.
The principal objective of the 16ng BoF is to identify what
limitations and considerations apply to IPv6 adoption over
IEEE 802.16(e), and to propose available solutions. The
working group may issue recommendations to IEEE 802.16(e)
suggesting protocol modifications for better IP support.
In 2006, WiBro deployment will begin, and the WiMAX Forum is
slated to specify IPv6 operation over IEEE 802.16(e) in 2006.
Accordingly, the working group will work and coordinate with
the WiMAX Forum and with the WiBro efforts.
