<p class="MsoNormal"><span lang="EN-US" style="font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D">Thank you for the reply. The interest sending rate is 100/sec although I checked it with 10/sec. In both the cases I found similar results. 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.<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US" style="font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D">I could not get this behavior if it is because of link issues, NFD issue or NDN Traffic generator issue. I tried asking the solution on the other
nfd-dev mailing list but could not get any response.<o:p></o:p></span></p>

as I am unable to get the data packets in response after a certain period of time. In my configuration I am making cs store size to be zero so that all interests can reach the producer. While investigating the issue of interest drops I found few errors in
the nfd logs. Below are the few errors which I am getting in the log file:</span><span style="font-size:11.0pt;font-family:"Calibri","sans-serif";color:black"><o:p></o:p></span></p>
