<br><font size=2 face="sans-serif">Sounds to me like we are nearly in violent
agreement. I thought it was you who coined the phrase "MIB replacement"
in the thread.. so I was just trying to speak your language. I agree we
should probably articulate the charter such that reasonable alternatives
may be considered or discovered... but I think we should also acknowledge
all 3 or 4 most vocal and interested parties (so far) seem to "anticipate"
the application of HTTP and XML to get the job done. When we built the
(very successful) Printer MIB standard... we did not embark in a vague
or general direction... I feel being as specific as we can about our goal
will help us achieve better results sooner. </font>

At least we both agree with Cathy.<br>
<br>
To answer your questions:<br>
<br>
a. Replacing MIBs as an object itself would inherently self justify the
effort. However, as a part of a solution, the need for such an effort
must be justified. <br>
<br>
b. You can define a PWG activity which, for the various reasons you
have cited, determines that developing a replacement for MIBs is a justifiable
object in itself. Quite frankly, I am not sure that I even understand
what you mean by a replacement for MIBs, and I suggest that some
examples may help. <br>
<br>
Regardless, at this point, your own position is that we have not adequately
scoped out the WBMM. Therefore, to preserve some order, I suggest that
we should not be considering solutions to a problem we have not defined,
but continue in an orderly way to scope out the objective.<br>
<br>
Indeed, even though I would agree that I see little alternative to HTTP,
probably XML, and quite possible SOAP as being components of the solution,
I would not define these in the objectives or even the requirements. Nor
would I refuse to entertain alternate ideas if reasonable ones were offered.
Again, I think that short-circuits the development process.<br>

Whether we define a "replacement for MIBs" as the result of "establishing
a transport, protocol and format as part of the solution" ... or we
do it because it is justifiable in itself... what's the difference? <br>
<br>
I wold argue it IS justifiable for reasons I cited in an earlier post..
not the least of which is resolving some of the force fitting we did with
the MIB (ex. MIB-II, hrMIB)... (ex. "magic decode ring"). <br>
<br>
Also, there are multiple models today (CIM, SNMP, NPAP etc.) which it would
be good to consolidate <br>
<br>
Also, this is an opportunity for the PWG to address MFP function which
we've shied from for, probably, too long. <br>

Differences

<br>
<br>
<br>
Identifying and resolving differences, and coming to consensus is one of
the main functions of a working group. So let see where the differences
really lie. <br>
<br>
I believe that scenarios add some specific to the general statements of
scope. Harry has outlined one, or maybe two here. I solicit from
whomever has an opinion on this whatever other scenarios they would like
addressed by this working group. <br>
<br>
I certainly agree that "management across the firewall"
is the basis for multiple scenarios. To me, the basic problem to
be solved. <br>
<br>
But is " standard protocol and NEW data model" to be taken
as an objective in itself , or is it part of the solution to the first?
<br>
<br>
Certainly, establishing a transport, a protocol, a format all need
to be defined as part of the solution. If there is a difference between
me and my fellow officers, it is that I do not agree that establishing
a replacement for MIBs (as has been cited earlier) is justifiable as an
objective in itself. Further, I am not convinced that it will be a necessary
part of the solution.... it may be, but that needs to be demonstrated.
<br>
<br>
It may be that the "differences" are just a matter of semantics.
I certainly do not suggest that ASN.1 be used to convey management data...but
it isn't used now either. What is communicated over SNMP is the OID and
the value. <br>
<br>
So I suggest that we start talking examples and scenarios to better define
the scope and objectives. Then we can sort through them and see how to
proceed. <br>
<br>
Unfortunately, we are now in the middle of a snow storm and I must fight
my way home, so my contribution will have to wait a while. But please,
take advantage of the New England weather and beat me to the punch! <br>

I'd like to try and resolve some of the (unfortunate) differences we are
having regarding Charter, Scope, Requirements. <br>
<br>
>From what I can decipher, there is a well established interest in solving
the problem "I've been getting at my (device) management data
remotely, within my enterprise just fine... but, now, how can I access
it across the firewall" (maybe to provide services to multiple enterprises
etc.). <br>
<br>
Others also want to solve... "... and what is the standard protocol
and data model that lends itself to the web services environment that may
be employed by proxy servers and/or directly in the embedded device".
<br>
<br>
Of course, we will have legacy SNMP devices to manage for quite some time
but I don't think the current existence of SNMP is the answer to the 2nd
question. <br>
