<li class="MsoListParagraph" style="margin-left:0in;mso-list:l0 level1 lfo1"><span style="font-size:11.0pt;font-family:"Calibri",sans-serif">Do you mean that each area presentation should start the Kerney graphic, highlighting the specific area of interest
as you did with the red dashed box for the SEA part? I certainly see the value and the message to the audience (“look I’m here and deal with these assets”), but I’m afraid it is a bit difficult for the other areas, since they are more or less all going from
one end to the other end, except probably SOIS. I think this could make sense if we take the animated version, remove the “lines and arrows” for the other areas and we keep those for our specific area.
</span><b><span style="font-size:11.0pt;color:#3B7D23;mso-style-textfill-fill-color:#3B7D23;mso-style-textfill-fill-alpha:100.0%"><<With SIS a lot of what you do is end-to-end, but you could show that by tracing one (or more) of the appropriate paths. For
CSS it is all on the ground between MOC and GS. For SOIS it is all on-board. For SLS it is all over the space link, one link at a time. For MOIMS it is really all in the MOC, but they do have ambitions for space.>>.</span></b><span lang="DE" style="font-size:11.0pt"><o:p></o:p></span></li><li class="MsoListParagraph" style="margin-left:0in;mso-list:l0 level1 lfo1"><span style="font-size:11.0pt;font-family:"Calibri",sans-serif">Slide 4 and following: I see on the space node BP running directly on top of USLP, but this is currently not supported
since BP has to go at least over EPP or SPP. </span><b><span style="font-size:11.0pt;color:#3B7D23;mso-style-textfill-fill-color:#3B7D23;mso-style-textfill-fill-alpha:100.0%"><<I can/will modify the diagram for accuracy to show EPP over USLP. It’s a “shim”,
but a required one.>>.</span></b><span lang="DE" style="font-size:11.0pt"><o:p></o:p></span></li><li class="MsoListParagraph" style="margin-left:0in;mso-list:l0 level1 lfo1"><span style="font-size:11.0pt;font-family:"Calibri",sans-serif">Slides 5 and 6 show essentially the same protocol stack but the space-to-ground link is either RF (X-band in slide 5)
or FSO (in slide 6). I’m wondering whether we really need two separated slides, while we could simply have a single side with a layer “C&S (RF or FSO”) and below “PHY (RF or FSO)”. I’m distinguishing here C&S RF from FSO counterpart, since the recommended
channel coding solutions are different. </span><b><span style="font-size:11.0pt;color:#3B7D23;mso-style-textfill-fill-color:#3B7D23;mso-style-textfill-fill-alpha:100.0%"><<I wanted to demonstrate that the bulk of our standards, which we designed in the RF
world, will also work over optical (FSO) with little change except for the FSO PHY and C&S layers. Slide 6 was intended to show the possibility of using “bespoke” comm services, but only if clearly defined “interoperability points” were carefully specified.
It’s a discussion point>></span></b><span style="font-size:11.0pt">.</span><span lang="DE" style="font-size:11.0pt"><o:p></o:p></span></li></ol>

<p class="MsoNormal"><span lang="DE" style="font-size:11.0pt"> <o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt">Dear Sami, Klaus-Juergen, et al,</span><span lang="DE" style="font-size:11.0pt"><o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt"> </span><span lang="DE" style="font-size:11.0pt"><o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt">I took a cut at a “abbreviated” set of slides for the SEA intro at the LIF. I know we just have 10 minutes apiece.</span><span lang="DE" style="font-size:11.0pt"><o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt"> </span><span lang="DE" style="font-size:11.0pt"><o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt">I took the approach of using the “Kearney animated CCSDS graphic” as a starting point because I think it will provide a useful “map” of how this area fits into CCSDS. I’d suggest that we all do the same and
that if we do we can just throw it up on the screen, say “here is what my area provides” and then get to the next slide with WG details. I turned off animation to make this quicker.</span><span lang="DE" style="font-size:11.0pt"><o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt"> </span><span lang="DE" style="font-size:11.0pt"><o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt">The second slide has “one-liner” sorts of details about the WGs in the area. I think that most of the areas will fit on one slide like this, SLS is (always) the notable exception. Ignacio probably needs
two such slides.</span><span lang="DE" style="font-size:11.0pt"><o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt"> </span><span lang="DE" style="font-size:11.0pt"><o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt">I added another slide which is the end-to-end DTN based architecture from the SCCS-ARD document. I think this is important because as an architecture slide it covers space, ground stations, user MOC, and
relay assets. It also covers SLS, SIS, CSS, and SEA, and provides some hints as to where MOIMS and SOIS attach to the comms layers. I did one quick overlay animation showing the two major interoperability points.</span><span lang="DE" style="font-size:11.0pt"><o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt"> </span><span lang="DE" style="font-size:11.0pt"><o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt">And I added two more copies of that same slide, one with an optical comm link shown, the second showing a “bespoke” commercial deployment and those same two interoperability points. </span><span lang="DE" style="font-size:11.0pt"><o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt"> </span><span lang="DE" style="font-size:11.0pt"><o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt">I think I can get through these in 10 minutes. And I think they will provide a map that all the rest of the areas can be located upon.</span><span lang="DE" style="font-size:11.0pt"><o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt"> </span><span lang="DE" style="font-size:11.0pt"><o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt">I assume that each of the other areas will have some sort of graphical content as well, or maybe we will all just use that same “Kearney” slide to show the crew where each area fits in. This will be a little
repetitive, but I think we can go over it quickly and get to the details. Maybe each area will also have some graphical view of some of its specific standards</span><span lang="DE" style="font-size:11.0pt"><o:p></o:p></span></p>
