we have now, then maybe an overview of SM&C from your folks, then discussion? I think Erik has CSS issues as well, so time might be tight but if we can at least do the intros maybe we can follow up offline.<o:p></o:p></span></p>

book would be the (forthcoming) Mission Operations Monitor & Control Services book? From our perspective when doing the Network Management piece of the work, we’ve been thinking of NM as an application, so the higher in the stack the interface to the services
NM uses, the better. Said differently, if we DTN NM can leverage the Monitor and Control services and the Monitor and Control services run over something that could be MAL, or not, or MAL with multiple protocol-bindings underneath, I don’t think that matters
to us so much (it does matter to us and, I would argue, to CCSDS overall, that the ‘scope’ of the messages be as large as possible per the previous paragraph, but that’s a different matter).<o:p></o:p></span></p>

<p class="MsoNormal" style="margin-left:.5in"><span style="font-size:10.0pt;font-family:"Arial","sans-serif"">Hi Keith,</span>
<br>
<br>
<span style="font-size:10.0pt;font-family:"Arial","sans-serif"">I have earmarked a 2h joint meeting with SIS-DTN in the agenda of SM&C WG starting at 13:30 of Thu 13Nov. Is that OK?</span>
<br>
<br>
<span style="font-size:10.0pt;font-family:"Arial","sans-serif"">Without pre-emptying the discussion, the MO SM&C Services provide a coherent set of services to monitor and control *any* remote (controllable) object, not necessarily only as spacecraft. The operations
of these services are defined in an abstract manner (via the MAL). For a specific deployment, and here I am touching on your question on "how those parameters are encoded and transported, the abstract services need to be mapped to a concrete encoding/transport.
This is achieved by a dedicated blue book at the level of MAL.</span> <br>
<br>
<span style="font-size:10.0pt;font-family:"Arial","sans-serif"">The bottom line is that</span>
<br>
<span style="font-size:10.0pt;font-family:"Arial","sans-serif"">- one can use the MO M&C services to monitor and control any remote object</span>
<br>
<span style="font-size:10.0pt;font-family:"Arial","sans-serif"">- one can select the most appropriate encoding/transport for its deployment of these services.</span>
<br>
<br>
<span style="font-size:10.0pt;font-family:"Arial","sans-serif"">I hope the above helps. How do you want to play the joint meeting? For instance, would you like to send us in advance a set of questions that you would like to be addressed?</span>
<br>
<br>
<span style="font-size:10.0pt;font-family:"Arial","sans-serif"">Thanks</span> <br>

<br>
<br>
<span style="font-size:13.5pt;font-family:"Calibri","sans-serif"">The SIS-DTN working group is about to start doing some work in the network management for the BP layers of the stack. Would it be possible for us to get a few hours together with SM&C to talk
about the interaction between the monitor and control services and what we (think we) need for DTN network management? I’m thinking just an hour or two for the two WGs to exchange their views of what’s going on would be really helpful to us.</span>
<br>
<span style="font-size:13.5pt;font-family:"Calibri","sans-serif""> </span> <br>
<span style="font-size:13.5pt;font-family:"Calibri","sans-serif"">From my interpretation of the 522.1-R-3 book, the MO SM&C Services provides a framework for (general-purpose) monitor and control, which is tailored towards spacecraft. *<b>IF</b>* I understand
correctly, a way for e.g. Bundle Protocol network management could ‘plug in’ to SM&C with a set of ‘drivers’ for the spacecraft to monitor / control the various BP parameters of interest according to the various SM&C services. [Is that a completely broken
characterization?] There’s then a question of how those parameters are encoded and transported.</span>
<br>
<span style="font-size:13.5pt;font-family:"Calibri","sans-serif""> </span> <br>
<span style="font-size:13.5pt;font-family:"Calibri","sans-serif"">Sometime Thursday (PM?) of the CCSDS meetings would be best for the SIS-DTN WG, but we’re meeting Thursday and Friday and if that wouldn’t work, I’ll find some other time.</span>
<br>
<span style="font-size:13.5pt;font-family:"Calibri","sans-serif""> </span> <br>
<span style="font-size:13.5pt;font-family:"Calibri","sans-serif"">I know that Erik and the CSS groups are interested in talking with you as well, and that would be a good time for them.</span>
