Re: I-D Action: draft-ietf-6man-6lobac-01.txt

[Kerry Lynn <[e-mail]>]

Greetings,

The main changes to the WG version of this draft are: a) tweaks that
resulted from the initial public review of the BACnet MS/TP change
proposal, the most significant being the COBS encoding of data and
data crc fields to remove preamble sequences; and b) addition of
two informative appendices to provide code examples for the data
crc and COBS encoder/decoder.  These appendices are insufficient
to implement the data link, but are provided e.g. for those writing
Wireshark dissectors or otherwise wanting more detail about over-
the-wire format.

I'd like to solicit specific comments on what is needed to move this
draft forward - IOW, what would you like to see added in order for
this draft to be ready for WGLC?

For anyone who'd like to view the details of data link state machines,
etc., I can provide the relevant clause (9) of the ASHRAE 135-2010
(BACnet) spec, as well as the MS/TP change proposal (Addendum
an).

Thanks, -K-
