<p class="MsoNormal"><span class="EmailStyle21"><o:p> </o:p></span></p>
<p class="MsoNormal"><span class="EmailStyle21">The reason for including the CESG in this email discussion was not to "SPAM" them, that would waste their time. Rather it was to make sure that they are a part of the discussion because they should be. You must
be aware that whatever fiddling you decide to do with the GFP at the SDLP to coding and synchronization interface also affects directly the CSS Area, for their SLE & CSTS service specs, Functional Resource (FR) model, Service Management, and architecture documents.
This is not just some SLS internal issue. And, because these effects cross Area boundaries it is a concern for SEA as well. It is in our charter to attend to such matters. This is the same sort of consideration that has brought attention on some of the
less than well thought out proposals from the Optical Com WG, like using Ethernet frames as space data link protocols. I would expect you to welcome such support and not to castigate it.<o:p></o:p></span></p>
<p class="MsoNormal"><span class="EmailStyle21"><o:p> </o:p></span></p>
<p class="MsoNormal"><span class="EmailStyle21">Perhaps the issue with the wording of that sentence is just a matter of your use of English. Perhaps what you meant to say was this:<o:p></o:p></span></p>
<p class="MsoNormal"><span class="EmailStyle21"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="font-size:14.0pt;font-family:"Times New Roman",serif;color:blue">However,
</span><span style="font-size:14.0pt;font-family:"Times New Roman",serif;color:red">introducing
</span><span style="font-size:14.0pt;font-family:"Times New Roman",serif;color:blue">the Generic Framing Procedure entails matters affecting
</span><span style="font-size:14.0pt;font-family:"Times New Roman",serif;color:red">the communications
</span><span style="font-size:14.0pt;font-family:"Times New Roman",serif;color:blue">architecture stack,

</span><br>
<br>
Lastly, I do want to remind you that even though this issue is technically within the SLS Area that it has ramifications well outside the area. I think that you should expect continued interest and attention to this and to the Optical WG. Unlike your continued
attention to matters occurring <u>inside</u> the CFDP WG, this is actually within the scope of SEA and is a direct concern of CSS.<o:p></o:p></p>

<span style="font-size:10.0pt;font-family:"Arial",sans-serif"> first of all I fail understanding how spamming the rest of CESG can help our discussion, but never mind.</span>
<br>
<span style="font-size:10.0pt;font-family:"Arial",sans-serif">Second, Margherita's sentence you comment does not state that SLP protocols need to be changed bur it rather puts accent on the impact on the "architecture stack".</span>
<br>
<span style="font-size:10.0pt;font-family:"Arial",sans-serif">Nobody in SLS Area Plenary meeting as well as (two) CESG Meetings mentioned adding data types or anything else to Space Data Link Protocols.</span>

<span style="font-size:10.0pt;font-family:"Arial",sans-serif">Gilles and I simply reported the result of the discussion in the SLS Plenary.</span>

What is stated in inaccurate by any measure since GFP does not have anything to say about space data link protocols. The only relationship that could possibly exist in the future would be to add another data type (or four) to the link layer protocols that
GFP would formally recognize. This requires no changes to those protocols, which is, in fact, a feature of GFP.<o:p></o:p></p>
