[MEXT] Multiple interfaces problems in MEXT and mif

Hi, all in MEXT and mif.

In IETF mif (Multiple Interface) mailing list (https://www.ietf.org/mailman/listinfo/mif),

we now discuss the host which would like to use multiple interfaces.

I understand that MEXT WG is also related to the use of multiple interfaces of a host
using Mobile IPv6 or a mobile router using NEMO Basic Support and their variants

MEXT WG is focuing on monami6 related topic (multiple CoA, Multiple HoA, and Multple HA, etc.,)
and extedning Mobile IPv6 and NEMO for these, but mif is not related to this direction.
In mif, source address selection, routing and DNS control protocol are consideration items
due to multiple interfaces of a host.

For mif’s scope, Jari Arkko made some comments and classification of problems.

http://www.ietf.org/mail-archive/web/mif/current/msg00050.html

Among these classification which includes access selection, split DNS, configuration reconciliation,
routing, address selection, tunnel multihoming, and the communication way between the host and
the network about their policies regarding all of the above, Jari said that access selection is already
coverd in RFC 5113 and tunnel multihoming is already covered in MEXT WG work items.

At monami6 WG in 64th IETF meetinng, I submitted and presented two Internet Drafts.

- Analysis of multiple interfaces in a Mobile Node

http://tools.ietf.org/id/draft-hong-multipleif-mn-pb-statement-00.txt

- Virtual network interface for multiple interfaces in a Mobile node using Mobile IPv6

http://tools.ietf.org/id/draft-hong-virtualif-mn-mipv6-00.txt

Because these two drafts were not in the monami6 WG’s scope and virtual network interface draft was

implementation specific, there were not adoped in monami6 WG’s work items. The intentions of two drafts
are supporting multiple interfaces of a host without extending Mobile IPv6/NEMO.

I think that multiple interfaces problems of a host are related to both Mobile IP/NEMO specific issues and
general network issues. Mobile IP/NEMO specific issues are related to extending of Mobile IP/NEMO and
these are already studied in MEXT WG and general network issues which were not related to
Mobile IP/NEMO could be studied in mif. As same manner, I think that my drafts could be discussed and
developed in mif. In the first draft (Analysis document), I classified multiple interface problems into
Mobile IPv6-sepcific issues, General network issues, and heterogeneous environment issues.

Including Hui Deng in mif, with regarding to these drafts, they want to hear comments from MEXT WG’s point of view,
because it seems that these drafts are quite related to monami6/MEXT WG. So, I ask MEXT to review whether there are

some overlap between MEXT works and my drafts or not.

It is appreciate to give comments.

Best regards.
