<p class="MsoNormal"><span style="font-size:11.0pt;color:#1F497D">During the telecon, as I remember, I presented the stuff, and we had some discussions, but in principle nothing has been agreed or decided, except I should put my comments into the Green Book
master copy, for future work. And that it needs to be done, but now definitely not a priority.<o:p></o:p></span></p>

<p class="MsoNormal"><span style="font-size:11.0pt;color:#1F497D">To the merit, I understand and I agree. Especially under the premise, that one day we want (because we want it, don’t we?) to implement the whole Configuration Profile landscape. What we try
now is to develop Simple Configuration Profiles, with hope later on, some nice day (when Marcin is retired and works as a freelancer for DLR/CCSDS) we will be able to plug it into the Complex Configuration Profile world and it will still work. This is tricky,
but let’s cross fingers. I also think we should watch out not to lose the focus, otherwise we risk not releasing the Simple Config Profiles book any time soon.<o:p></o:p></span></p>

<p class="MsoNormal"><span style="font-size:11.0pt;color:#1F497D">Anyway, this was just my comment to your mail. What I propose is, I will take your mail (I think it is very valuable) and put it into the master copy of the Green Book in the respective place,
for whomever in future to edit it.<o:p></o:p></span></p>

<p class="MsoNormal"><span style="font-size:11.0pt;color:#1F497D">Dear Marcin,<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt;color:#1F497D">I am sorry that I was not able to participate in this discussion last month. I have comments on two items in particular in your briefing. Depending on the discussion that took place at the meeting,
these comments may now be overcome by events, but I’ll make them anyway and you can inform me as to whether they are still relevant.<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt;color:#1F497D"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt;color:#1F497D">My comments concern items 11 and 12, in which you state that we might not need the notions of Abstract Service Components and Service Component anymore, and use only the concept of Functional
Resource. While – as you have noted in previous items in your briefing – the terms “Abstract Service Component” and “Service Component” will/should be replaced in the Functional Resource Reference Model with the terms “Functional Resource Stratum” and “Functional
Resource Set”, respectively, the <b>concepts </b>of Functional Resource Stratum and Functional Resource Set are important to the concept of even the simplified Configuration Profiles and should not be ignored in the ESCCS-SM Concept book.<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt;color:#1F497D"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt;color:#1F497D">To review those concepts:
<o:p></o:p></span></p>
<p class="MsoListParagraph" style="text-indent:-18.0pt;mso-list:l0 level1 lfo2"><![if !supportLists]><span style="font-size:11.0pt;color:#1F497D"><span style="mso-list:Ignore">-<span style="font:7.0pt "Times New Roman"">
</span></span></span><![endif]><span style="font-size:11.0pt;color:#1F497D">A <i>
Functional Resource Stratum</i> is an abstract layer of functionality in the Functional Resources Reference Model. In general, each FR Stratum is defined in terms of the abstractly-defined functions that are performed by that stratum and the
<i>essential</i> Service Access Point (SAP) that it provides and the essential SAP type that it accesses. The FR Strata are equivalent to the Internet Protocol Suite (a.k.a. TCP/IP) and ISO/OSI notions of layers, where (for example) in the Internet Protocol
Suite the abstract Transport Layer can be filled by either TCP or UDP.<o:p></o:p></span></p>
<p class="MsoListParagraph" style="text-indent:-18.0pt;mso-list:l0 level1 lfo2"><![if !supportLists]><span style="font-size:11.0pt;color:#1F497D"><span style="mso-list:Ignore">-<span style="font:7.0pt "Times New Roman"">
</span></span></span><![endif]><span style="font-size:11.0pt;color:#1F497D">Even though the SAPs/Accessors of the individual FR strata are fixed by the model, the specific functionality is not. It is this abstraction of functionality that allows multiple concrete
<i>Functional Resource Sets</i> to plug into a specific stratum. So, for example, in our projected current set of simplified Configuration Profiles, we include Functional Resource Sets for Forward CCSDS 401 Space Link Carrier Transmission (in the Forward Physical
Channel Transmission FR Stratum), Return CCSDS 401 Space Link Carriers (in the Return Physical Channel Reception FR Stratum), Forward TC Space Link Protocol and Forward AOS Space Link Protocol (both in the Forward Space Link Protocol Transmission FR Stratum),
and Return Space Link Protocol (in the Return Space Link Protocol FR Stratum). <o:p>
</o:p></span></p>
<p class="MsoListParagraph"><span style="font-size:11.0pt;color:#1F497D"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt;color:#1F497D">We <b>know</b> that in the (near) future we will also need to add FR Sets corresponding to CCSDS 405 (CDMA RF modulation used by NASA Space Network) to the respective Physical Channel FR strata
and the Unified Space Data Link Protocol FR Sets corresponding to the respective Space Link Protocol strata. Even though our concrete efforts in the near term will be to create the simplified Configuration Profiles in terms of the identified “cookie cutters”,
those cookie cutters must still conform to the larger FR Strata model or we will paint ourselves into a corner from which we will not be able to escape. It is my opinion that the ESCCS-SM Concept Green Book should recognize that larger FR Strata/FR Set model
since it is a fundamentally crucial concept for extending the sets of resources that Service Management can encompass. Of course, as you point out, the amount of work required to make the necessary terminology and notional changes in the Concept Green Book
will be nontrivial, but I do think that the (revised) concepts should still be included.<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt;color:#1F497D"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt;color:#1F497D">I haven’t seen that there are any summary minutes of the discussion at the Spring meeting on this topic, so I don’t know what the WG discussed or concluded. If it would be appropriate, we can
discuss this topic at the 27 June telecon.<o:p></o:p></span></p>
