RE: UNISWG 2nd Draft Report

Lorenzo:

I like to take this opportunity to repeat what we discussed briefly on
Tuesday, February 24.  Basically, there are three new ID's proposals on
the table: one for the new expend Internet address (IP Version 6 or
IPv6), one for home plug & play (CIC Home PnP version 1.0), and one for
California UNIS.  All these three ID's can be applied to the same
device, a meter.  Therefore, it would be nice to have some common design
principle link all three ID proposals.

Martin Burns proposed UNIS uses a 128-bit ID (see his 2/22 web posting
under UNISWG) which I think is very interesting.  The Internet IPv6 also
has 128-bit ID address - with 64-bit for local intranet assignment.  I
would like to propose that we have some intelligent UNI that is 64-bit
long which can be dropped into Internet 128-bit IP address (dot format)
very nicely, either via MDMA, or ESP/MSP or whatever.  In this case,
MDMA or ESP/MSP will function as ISP (Internet Service Provider) by
adding the upper 64-bit Internet address to complete the 128-bit.  This
will provide a unique location ID (and the same Internet IP address) for
all meters as well as all other local devices.  Currently, NIC is the
registration authority for Internet IP Version 4 address (domain name
system).

Manufacturer ID, product model ID models, serial number etc. can be
handled within the 64-bit Intranet address portion.  I believe this
Internet UNIS approach will facilite greater communication
interoperability worldwide.  Any of your feedback comments are welcome.
