Hi Hemant,

Yes, let's find some time for sure.  We have a draft proposal to discuss
with Stuart Cheshire on extending m-DNS for site local multicasts
(http://datatracker.ietf.org/doc/draft-lynn-dnsext-site-mdns/) plus we are
working on a white paper covering the following topics (note the white paper
is for discussion and portions may make sense for incorporation into the
advanced CPE requirements draft):

1)    White paper to address allocation of ULA prefixes, ULA address
autoconfiguration and DAD, rules on limiting propagation of ULA prefixes
beyond residence boundaries
      a. Define location where the ULA prefix is generated (default values
if we can agree to them also)
      b. Define mechanism to distribute ULA prefixes
      c. Define mechanism to create unique ULA addresses from prefix (or
more likely point to other drafts which do this like Autoconf)
      d. Define mechanism to stop propagation of ULA prefixes (which is
probably the start of a much more complex problem)
      e. Propose either delegation (and realignment/DAD of updated ULA
addresses) or a proxy and proxy agent to interconnect different ULA domains
in a residence

3)      White paper to define how an LBR (6LoWPAN border router) gets it
global prefix to use (from the prefix space of the subscriber network).    
      a.   Probably use DHCP on the LBR to allocate the prefix from the
subscriber network.

As soon as our schedule is known, I will drop you a note and see if we can
get together for 1-2 hours to discuss.

Don

Don,

Good to hear from you.  I am also attending the IETF in Prague. I'd be
happy to sit down with you guys again (like we did in Beijing) and work
out the issues.

Hi Hermant,

Both Tom Herbst and myself (Don Sturek, representing Pacific Gas and
Electric) will be in Prague and would like to discuss further the CPE
Enhancements draft and the requirements around internetworked CPE within
a
home.

As outlined in the
http://tools.ietf.org/html/draft-herbst-v6ops-cpeenhancements-00 draft,
activities are underway to deploy IPv6 enabled smart meters as well as
support in WiFi and HomePlug to internetwork these smart meters with
existing home networks connected to existing ISPs.

The scenarios described in the draft are a little more than a year from
large scale deployment (11 million smart meters installed to date)

Don

>Huh?  Where is the draft that documents this?

http://tools.ietf.org/html/draft-herbst-v6ops-cpeenhancements-00

Snipped from the Abstract of the document above, is this text between
squared brackets.

[WiFi access points, cable boxes and other home devices with internet
access could all be internetworked with smart metering devices by
customers with no data networking expertise resulting in a complex
multi-segment network with differing prefixes, routing support and
service discovery needs.]

I am sure there is other text in the document that points out two
different routers in the home connected to two different SPs (one SP is
the home's DSL or broadband SP and the other SP is the Power Grid
company with their IPv6 CE router for the home) and thus one has a
multihomed home.  Anyway, you should look at Tom Herbst's prezo given to
the v6ops at the IETF79 in Beijing that clearly shows a multihomed
network.  Note also that multihomed involves both a multihomed WAN and
LAN for CE Router.

Hemant
