I think they’ve improved the book’s overall quality.<o:p></o:p></span></p><p class=MsoNormal><span style='font-size:14.0pt'><o:p> </o:p></span></p><p class=MsoNormal><span style='font-size:14.0pt'><o:p> </o:p></span></p><p class=MsoNormal><span style='font-size:14.0pt'>Regarding your RID against the Delay-Tolerant Payload Conditioning Specification:<o:p></o:p></span></p><p class=MsoNormal style='margin-left:.5in'><span style='font-size:14.0pt'>I am wondering if "Annex E Delay-Tolerant Payload Conditioning Specification" should not be a separate document. For me it is a specific way (an “application service”) of how to apply BP and does not need to be part of the CCSDS BP Standard. Also, I am not sure about the maturity of that protocol (Has it been tested with two independent implementations?). So, it might be better to separate it (maybe as a Magenta Book) and have "independent lifecycles".<o:p></o:p></span></p><p class=MsoNormal style='margin-left:.5in'><span style='font-size:14.0pt'><o:p> </o:p></span></p><p class=MsoNormal><span style='font-size:14.0pt'><o:p> </o:p></span></p><p class=MsoNormal><span style='font-size:14.0pt'>I think the WG’s current leaning is to reject the RID and keep the DTPC annex in the book. I would concur that in a perfect world it would be split off as a separate book, but as I recall the capability was strongly desired and there was some concern about ‘# of books explosion’ and the agency review resources that would be needed if it were done separately. Also, removing the annex now would require another agency review.<o:p></o:p></span></p><p class=MsoNormal><span style='font-size:14.0pt'><o:p> </o:p></span></p><p class=MsoNormal><span style='font-size:14.0pt'>There are two implementations of DTPC (ION and DTN2), and since it’s a normative part of the book it WILL be interoperability tested before the book goes Blue.<o:p></o:p></span></p><p class=MsoNormal><span style='font-size:14.0pt'><o:p> </o:p></span></p><p class=MsoNormal><span style='font-size:14.0pt'><o:p> </o:p></span></p><p class=MsoNormal><span style='font-size:14.0pt'>Given the above, I think the WG would like to reject the RID and keep DTPC in the current book.
