<p class="MsoNormal"><span lang="EN-US">Dear SDLS WG member,<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US"><o:p> </o:p></span></p>
<p class="MsoNormal"><span lang="EN-US">Please find attached the updated SDLS Green Book – Issue 2, taking into account the response to the comments formulated by SEA AD (see attached mail) and the action items from our last meeting (01/04)(see attached MoM).
The only comment not taken into account (general comment #5) is the one related to the application of SDLS to Inter-Satellite Links or space-to-space links, scenarios which we do not tackle in the present edition of the SDLS GB. How should we document, in
the SDLS GB, the space-to-space scenarios ? I propose we discuss and come up with a text during the meeting. In the SDLS EP GB, we simply mention that SDLS can be used for space-to-space links but in a master-slave configuration (Initiator-Recipient). The
text is the following :<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US"><o:p> </o:p></span></p>
<p class="MsoNormal"><span lang="EN-US">“ SDLS Extended Procedures are designed to operate in a master-slave configuration. For nominal ground-to-space and space-to-ground links, the master is the mission operations center. It is also possible to use the
Extended Procedures for managing space-to-space links. In all cases, there is no negotiation between endpoints: all directives are issued from a predetermined master (referred to as Initiator in [</span><span lang="EN-US">2</span><span lang="EN-US">]) toward
a predetermined slave (referred to as Recipient in [</span><span lang="EN-US">2</span><span lang="EN-US">]).”
<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US">Shall we stay as brief or elaborate more on the limitations of SDLS when used for ISL ?<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US"><o:p> </o:p></span></p>
<p class="MsoNormal"><span lang="EN-US">Looking forward to a fruitful meeting (in real this time !)<o:p></o:p></span></p>
