<p>Some observations:</p>
<p><br>
</p>
<p>1) I think the "interface went down" error appears when you quit Mini-NDN and NFD is killed.</p>
<p><br>
</p>
<p>2) When I tried interval as 1ms (count: 1000) - no loss for the first 4 tries, on the 5th time I see the same problem.</p>
<p><br>
</p>
<p>3) I turned on ndndump and found that sa suddenly stops responding with data - not sure why. For some time, it seems, interest do reach sa without it responding.</p>
<p><br>
</p>
<p>Can you modify your experiment as below and trace interest/data and see if you can find where it fails:</p>
<p><br>

<div> for intf in host.intfNames():</div>
<div> ndnDumpOutputFile = "dump.%s_%s" % (intf, str(host.intf(intf).IP()))</div>
<div> host.cmd("sudo ndndump -f '.*nle.*' -i %s > %s &" % (intf, ndnDumpOutputFile))</div>
<div> if host.name == 'ca':</div>

Interesting is the data generation and arrival time. The data transfer behaves perfectly fine for initial few interests while after a certain time it just stops and the requested data then is arrives just after the interfaces goes down(I guess mostly when
I am stopping the Mininet topology) and are marked as unsolicited data.</span><span style="color:black"><o:p></o:p></span></p>
