<li class="MsoListParagraph" style="margin-left:0cm;mso-list:l0 level1 lfo1"><span lang="EN-US" style="font-family:"Calibri",sans-serif">I see no mention of optical communications, while the lunar WG within IOAG was pointing to them too. Any reason for excluding
them now from the picture?<o:p></o:p></span></li><li class="MsoListParagraph" style="margin-left:0cm;mso-list:l0 level1 lfo1"><span lang="EN-US" style="font-family:"Calibri",sans-serif">The SOIS-WIR WG has been working on green and blue books about the communication solutions for in-situ planetary network,
possibly resulting in the coexistence of 3GPP/WiFi solutions with DTN-based ones. Is this also captured in the pictures you have put in your slides?<o:p></o:p></span></li><li class="MsoListParagraph" style="margin-left:0cm;mso-list:l0 level1 lfo1"><span lang="EN-US" style="font-family:"Calibri",sans-serif">As to where push information about all (and possibly other) DTN reference scenarios, let’s not forget that we have the CCSDS
734.0-G-1 “Rationale, Scenarios, and Requirements for DTN in Space” which is since long (the document was published already in 2010) in our ToDo list for the 5-year review. Probably the material you provided in the slides could be further elaborated and expanded
for a new version of that green book. In any case it is probably now time to think how and when to start the 5-year review of that book (I know all our resources are on the blue and orange books, but that green book is really old and must be refreshed)<o:p></o:p></span></li></ol>

<p class="MsoNormal"><span lang="EN-US" style="font-family:"Calibri",sans-serif">Just another point somehow correlated to scenarios: during the monthly telco between SIS and IETF DTN WG, it emerged that IETF would like to come up with a concept/white paper
about the challenges of space internetworking. Moreover, a first step would be to review and update RFC4838 which now contains some outdated content that should be revised. I add here Ed who can say a few words more on this point.<o:p></o:p></span></p>
