<font size=2 face="sans-serif">Hi Nestor,</font>
<br>
<br><font size=2 face="sans-serif">How does this relate to the question
asked by Scott? If I understand correctly, he is asking if they can use
the SM&C application layer M&C services (Parameter and Aggregation
Service) for retrieving TM items, which are related to DTN-management (e.g.
the status of each node, the ping time to the next node, ...)</font>
<br>
<br><font size=2 face="sans-serif">I guess at communication layer, for
each scenario (deep space or not) an appropriate DTN protocol and convergence
layer will be selected but if you want to transfer DTN management telemetry
items, it means you are using DTN in the first place, right? As far as
the MO services are concerned, what you need to do is to define a communication
protocol binding for MAL to whatever DTN protocol you use (e.g. BP or another).</font>
<br>
<br><font size=2 face="sans-serif">The METERON case is the proof of concept
of how such binding works. For a different deployment a different binding
(or encoding) may be needed but the concept is the same.</font>
<br>
<br><font size=2 face="sans-serif">So, I think the answer is: Yes you can
use the MO Parameter or Aggregation service for doing what you want to
do and yes you can bind it to whatever DTN protocol suitable for your deployment,
similar to what we have done for METERON.</font>
<br>
<br><font size=2 face="sans-serif">But I may be missing something here.</font>

If I may add one more detail, which may be of interest to Scott:</font><font size=3>
<br>
</font><font size=2 face="sans-serif"><br>
In the context of the METERON project, ESA has already implemented, deployed
and operationally validated some of the MO M&C services to publish
a various set of TM parameters (which were not Spacecraft related but for
instance related to the health status of a laptop and even the status of
a button on particular software running on that laptop on the ISS) using
DTN BP at communication layer (we used ION 2.3 and are currently updating
to ION 3.2).</font><font size=3> <br>
</font><font size=2 face="sans-serif"><br>
We have also implemented a so called BPPing Agent, which was deployed on
each DTN node and periodically pinged other nodes. The results of the BPPings
were then published to all intersted listeners (our M&C system instances)
using again the related MO M&C Parameter service.</font><font size=3>
<br>
</font><font size=2 face="sans-serif"><br>
In practice, the mentioned M&C service were used to publish and receive
the TM parameters encoded in binary over BP over Channel Protocol (the
convergence layer below BP) from ISS to the ground. The exact same implementation
of these services (same code at run-time) had published a second endpoint
to provide the same functionality via a different protocol (XML encoding
over HTTP) on the ground.</font><font size=3> <br>
</font><font size=2 face="sans-serif"><br>
So basically two set of different consumers have used the same services
to retrieve the TM, using the communication protocol of their choice. If
you are interested, I can prepare a presentation for the discussion session.
I have added Sebastian in cc, who is our DTN expert, in case of DTN specific
questions.</font><font size=3> <br>

Hi Keith,</font><font size=3> </font><font size=2 face="Arial"><br>
<br>
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?</font><font size=3> </font><font size=2 face="Arial"><br>
<br>
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.</font><font size=3> </font><font size=2 face="Arial"><br>
<br>
The bottom line is that</font><font size=3> </font><font size=2 face="Arial"><br>
- one can use the MO M&C services to monitor and control any remote
object</font><font size=3> </font><font size=2 face="Arial"><br>
- one can select the most appropriate encoding/transport for its deployment
of these services.</font><font size=3> </font><font size=2 face="Arial"><br>
<br>
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?</font><font size=3> </font><font size=2 face="Arial"><br>

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.</font><font size=3> <br>
</font><font size=4 face="Calibri"><br>
>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.</font><font size=3>
<br>
</font><font size=4 face="Calibri"><br>
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.</font><font size=3> <br>
</font><font size=4 face="Calibri"><br>
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.</font><font size=3> <br>
