RE: LMP fraud

["Bernstein, Greg" <GregB@ciena.com>]

As you indicate SONET/SDH is but one technology that LMP purports to apply.
As a optical transport technology it tends to be quite fully featured with
regard to performance monitoring, fault management, protection, etc...  This
makes it quite different from ATM, Frame Relay (a higher layer service) or
Ethernet a LAN service (now moving to the WAN).  Hence we don't tend to see
nearly as much overlap.

BTW, strange tone comming from a WG chair. If the document has been approved
let folks know.  We thought that this was a period within which comments
were solicited.

Fault localization is just *one* of LMP's many functions, and SONET
is just *one* encoding that can be used.

The confusion is yours, as you insist that you are "burdened with
supporting LMP".  If you think you don't need to support LMP, then
don't.

CCAMP "ventured" into this area over two years ago.  Most of the folks
working on LMP do know a bit about transport networks.

As I see it, in your opinion, LMP is an unnecessary protocol in a forum
that knows little about transport.  Meantime, you've proposed various
fixes to what is in your opinion an unnecessary protocol for over two
months now, and there hasn't been much support for your fixes.  So, at
this point, what are you trying to achieve?
