I haven't made much headway on the document but have had some discussions about our course and options (interoperability on the ground vs. full-up protocol profile for space missions). I've gotten some buy-in for our current approach of specifying mechanisms for terrestrial interoperability (essentially 'via SLE' and 'pulling IP packets out at the ground station').</FONT></SPAN></DIV> <DIV><SPAN class="765003216-04012007"><FONT face="Arial"></FONT></SPAN> </DIV> <DIV><SPAN class="765003216-04012007"><FONT face="Arial">We're also on the hook for a lunchtime presentation during the meetings. I think using this time to talk about how IP could function (including review of how IP works and the terrestrial interoperability options, emphasizing that we can get terrestrial interoperability with little or no change to existing mechanisms) is the way to go.</FONT></SPAN></DIV> <DIV><SPAN class="765003216-04012007"><FONT face="Arial"></FONT></SPAN> </DIV> <DIV><SPAN class="765003216-04012007"><FONT face="Arial"></FONT></SPAN> </DIV> <DIV><SPAN class="765003216-04012007"> <FONT face="Arial">--keith</FONT></SPAN></DIV> <DIV><SPAN class="765003216-04012007"><FONT face="Arial"></FONT></SPAN> </DIV> <DIV><SPAN class="765003216-04012007"><FONT face="Arial"></FONT></SPAN> </DIV><DIV style="margin-top: 0px; margin-right: 0px; margin-bottom: 0px; margin-left: 0px; ">_______________________________________________</DIV><DIV style="margin-top: 0px; margin-right: 0px; margin-bottom: 0px; margin-left: 0px; ">Sis-CSI mailing list</DIV><DIV style="margin-top: 0px; margin-right: 0px; margin-bottom: 0px; margin-left: 0px; "><A href="mailto:Sis-CSI@mailman.ccsds.org">Sis-CSI@mailman.ccsds.org</A></DIV><DIV style="margin-top: 0px; margin-right: 0px; margin-bottom: 0px; margin-left: 0px; "><A href="http://mailman.ccsds.org/cgi-bin/mailman/listinfo/sis-csi">http://mailman.ccsds.org/cgi-bin/mailman/listinfo/sis-csi</A></DIV> </BLOCKQUOTE></DIV><BR><DIV> <SPAN class="Apple-style-span" style="border-collapse: separate; border-spacing: 0px 0px; color: rgb(0, 0, 0); font-family: Helvetica; font-size: 12px; font-style: normal; font-variant: normal; font-weight: normal; letter-spacing: normal; line-height: normal; text-align: auto; -khtml-text-decorations-in-effect: none; text-indent: 0px; -apple-text-size-adjust: auto; text-transform: none; orphans: 2; white-space: normal; widows: 2; word-spacing: 0px; "><DIV>James L.
