Hi Jari

I accept Vidya's suggestion to request your involvement.

As for "Automatic LMA discovery" WG item, Netlmm charter says " This will
define the ability for MAGs to automatically discover and use an LMA within
a
PMIPv6 domain. The scope of this effort may include specifying the use of
DNS or DHCP based LMA discovery or LMA discovery using policy information
retrieved via AAA protocols"

DHCP solution is valuable for the scenario that LMA and HA are collocated
(e.g. in 3GPP/WiMAX), and LMA/HA availability information is  stored in a
DHCP server( 3GPP 24.303  "Home agent address discovery based on DHCPv6").

IMHO, the chairs try to exclude DHCP solution from the chartered WG item
without soliciting enough technical comments.

BR
Frank

Jonne,
I can certainly take this draft from here on - however, I'd like people to
note that the WG document has been operating in conformance to WG consensus.
I have expressed earlier already that it is time to move on from this issue.


Frank, please take this offline to our AD if you are convinced that anything
needs to be done here.  At this point, this discussion does not belong on
the mailing list. 

Thanks,
Vidya

Hi Frank,

I really hope that other people would talk to this point. It seems that we
have one person pushing for a technology and complaining me having a bias on
this topic.

For the record, yes, the author of this document does work for the same
company as I do. Yes, this is a possible conflict of interest. However, we
are not talking about pushing a document that would be "my employer's
draft". We have a working group document, which we - as the WG - would like
to get finished.

Frank and Behcet, you have proposed additions to the WG document. However,
as far as I can see, it is just you. There are no other people active in
this discussion. Nobody is voicing their support for your proposal.

If other people are, I hope they feel free to comment. Only way to measure
support in the IETF is by seeing who speaks up. I know that both of you
state that there would be support that people have indicated to you
privately. Maybe you can encourage them to become public on the list.

I think we should stop discussing the administrative issue here. Frank, and
Behcet, if you have an objection or concerns to the process of this WG,
or/and my impartiality as a chair, I hope you know you can always complain
to Jari and bring this issues up with him.

However, as my impartiality has been put under question, I think the
cleanest thing is to have Vidya to take care of this draft now that she is
back at work. Just for the record, I only started this WGLC because Vidya
wasn't back from her leave at that time.

Vidya, is this ok with you?

Cheers,

Jonne.
