[Mip6] RE: A New BoF [16ng BoF: IPv6 over IEEE 802.16(e) Networks]

[장희진]

The first goal might be to run IPv6 basic operation over 802.16/(e).
Additionally, based on that, the interaction betwwen 802.16e and IPv6 for the seamless IPv6 mobility could fall in the scope as written in the charter. :)

-from a part of the charter -
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.


----- Original Message ----- 

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?
