<div>Hi folks,</div>
<div><br>
</div>
<div>We are facing this scenario in a few applications:</div>
<div><br>
</div>
<div>1) Interest received by NFD, passed to an application</div>
<div>2) Application not able to respond to interest, so interest stays in NFD PIT</div>
<div>3) Some time passes, but not enough for the Interest to expire</div>
<div>4) Application generates data (e.g., from a sensor reading) that would answer the Interest in the NFD PIT</div>
<div><br>
</div>
<div>Question: How does app know to inform NFD it has the data after step 4, and how should it do that? </div>
<div><br>
</div>
<div>- In this type of app, should it push the data unsolicited to the NFD and let it decide if there is something to do? </div>
</div>
</blockquote>
<div><br>
</div>
<div>In my opinion, as long as the application is certain that the Interest has arrived and is stored in NFD's PIT, it can just push the data out to NFD.</div>
</div>
</div>

<div>How certain does it have to be? There is a chance it could have expired...</div>

<div>- Is it recommended to implement an application-level PIT so the app is sure this data is solicited? (Why add <i>another</i> PIT?) </div>
