Hi Jouni and all,
Thanks for updating the charter, which is much tidy now.
Sorry for my late response, but I have a couple of comments below:
o With regard to enhanced mobility anchoring (mid-session anchor
switching), there were a lot of discussions in the past as you know and
eventually that idea was not fully accepted by the community. It's ok to
handle it in DMM WG, but we also need convincing use cases and
effectiveness. Re-anchoring LMAs/HAs with preserving IP address may not
be so elegant and efficient.
Right. The charter does not enforce preserving the IP during the switch,
actually. It would be a desirable feature tough.
o I was not very sure why virtualization needs to be mentioned. There
might have been some discussion about it, but do we really need it in
the charter?
The DMM solutions should not distinguish between physical or
virtualised networking functions. However, whenever applicable,
clarifications for specific networking function deployment models
are in scope and encouraged.
I still keep it for the time being. Several folk seem to think it needs
to be mentioned..
o The fourth paragraph mentions
UP/CP separation, but the last sentence is about IP address change,
which is described in the fifth paragraph. That sentence may be fit there.
In contrast to existing IETF standard IP mobility protocols,
mobility management signalling paths and end user traffic
forwarding paths may differ; those mobility related functions may
be located in separate network nodes. "Solutions may also specify
the selection between the care-of addresses and home
address(es)/prefix(es) for different application use cases".
Ack. Done.

Folks,
New update (v9) available. I added most of the editorials from Charlie
(thanks) and the red texts from Alper.
The lot debated anchoring term (and milestone) is still there. The
milestone does not mention anymore about preserving the mobility
sessions and stuff. That would be up to the solution to define.

Folks,
Minor changes..

IMHO..the charter as it is today, would allow pretty much any solution
from legacy anchoring to herd of pigeons carrying IP.. ;-)
I have put in editorial changes of my own and clear text proposals
received from others.
