<p class="MsoNormal"><span lang="EN-US">Question: Shall the Packet service provide only PUBSUB style of streaming or shall it also support Req/resp style of retrieval (from t1 to t2)?<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US">If the latter is the case, do we need to add a similar pattern to other M&C services, i.e. Parameter Service, Aggregation Service, Alert Service?<o:p></o:p></span></p>

<p class="MsoNormal"><span lang="EN-US">CNES, DLR and ESA delivered use cases and presented them. Nasa input is missing.
<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US">In general two scenarios are observed + one added by Roger.<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US">Scenario 1: Predefined set of products are available for retrieval. The consumer can browse and retrieve them.<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">Scenario 2: Consumer can request a product and then retrieve it. If the product is generically produced or already available is transparent to the consumer. Which products the consumer can request and with which parameters
are fixed in an ICD. <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">Scenario 3: Consumer can register interest in a product without knowing if and when it will become available. The service will deliver it to the consumer if and when it becomes available.
<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">It was observed that both push and pull modes are used. Security is a consideration for the choice.
<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US">It was also observed that generic file transfer mechanism is a means of data distribution.
<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US">Serge highlighted that CCSDS has already a standard for generic terrestrial file transfer and we should check it out first.<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US">Next step is to get NASA input. Peter Collins will update ESA slides to align them with the CNES and DLR style of input. Mehran Sarkarati will distribute the presentation.
