Thomas,
As one of the "loud" ones, I wish you would stop persisting in
your claim
that the discovery mechanisms that already exist are
"proprietary" and
"almost certainly not available to all implementers under RAND
(reasonable
and non-discriminatory) terms". I have noted a number of times in
your
presence, with your acknowledgement, there are a number of IETF
discovery
systems in place (free, and following IETF rules) including SLP (rfc2608
and
its derivatives), DDDS (rfc3958) and multicast-DNS/DNS-SD
(www.dns-sd.org,
based on rfc2782). There are *many* others (too many, really).
The industry is moving towards a UPnP-based system which, while based
on
various RFCs, is somewhat unique, and is a bit encumbered with IP
issues.
This issues, however, have NOTHING to do with RAND (all parties are
committed to RAND ... and indeed to *free* licensing).
There are NO, repeat NO "proprietary" protocols involved in all
this. If you
know of one, please be specific. I'm involved with at least three
industry
efforts, and I find myself at a loss to understand your insistence that
there is a problem.
Finally, why do we need a layer 2 service discovery protocol to be
"competitive"? With whom? The only kind of discovery a layer 2
protocol
needs is one that is required by the protocol itself ... such as a
common
synchronization source or "grand master" as it's called in IEEE
1588. Beyond
that, we are getting into some rather major layering issues ...

Actually your posting dose bring to mind a concern about the Re Par
Many if not most of the members of the RE Study Group, or at least
a few loud ones, are against the development of a layer 2 Service
Discovery protocol for Re. Favoring instead to use previously developed
proprietary protocols. My concern lies in the concept that such proprietary
protocols will almost certainly not be available to all implementors under
reasonable non discriminatory terms. Leaving the future Re Industry in
something of a patent licensing quagmire. Many have suggested the
existence of layer 3 standard protocols is sufficient, but I disagree.
I believe that we need a clean Layer 2 only architecture to be competitive.
So I advocate the inclusion of an objective probably in the 802.1 Re Par
to specify a Layer 2 Service Discovery Protocol. Further more I would
suggest that both the 802.3 and 802.1 PARs be held, without consideration,
until the issue is resolved.
