Re: AW: new I-D on HA filtering

Hi Koojana and all,

This is exatly our attend.

I would like to propose to the mobileip WG that we create a design team 
in order to work on multiple interfaces and multiple CoAs issues in MIPv6.

I think about writing a WG draft that regroups all ideas listed in each 
individual drafts:
    - draft-soliman-mobileip-flow-move-03.txt
    - draft-montavont-mobileip-ha-filtering-v6-00.txt
    - draft-nomadv6-mobileip-filters-00.txt
    - draft-wakikawa-mobileip-multiplecoa-01.txt
    - draft-montavont-mobileip-mmi-00.txt, obsoleted, but always 
available at 
http://www-r2.u-strasbg.fr/~montavont/draft-montavont-mobileip-mmi-00.txt

The common I-D should define:
    - How a multiple interfaces MN should use MIPv6: discuss how a MN 
may use MIPv6 when it has several interfaces/CoAs, several home 
addresses... without any change to MIPv6
    - Then describe extensions to MIPv6, in order to
        - perform multiple CoAs registration for the same home address
        - perform per-flow movement with any CNs based on the quintuplet 
identification of IPv6 flow label
        - perform packets filtering on HA (and CN ?)

Who agree with this idea ?
