I "temporarily" broke the functionality to configure Selectors (which AnswerOriginKind is part of), but it can be relatively easy added back. The main reason for this regression is that I wanted to have a packet format that incurs lesser overhead (you can check out the current packet format used by ndnSIM here: <a href="http://ndnsim.net/new-packet-formats.html">http://ndnsim.net/new-packet-formats.html</a>). Would you have time to help me implementing this functionality? </div><div><br></div><div>Btw. There is always an option to revert back to CCNx-compatible format (old files are in disabled/ folder), but I was planning to have an option to select packet format in the next (major) release of ndnSIM.</div><div><br></div><div>Another btw. After "re-adding" the ability to set AnswerOriginKind, there is also a need to implement logic of this selector in the forwarding strategy (not currently there).</div><div><br></div><div>---</div><div><br></div><div>About the fist question.</div><div>ns3::ndn::Consumer is a very simplified implementation of the consumer and in your case you may want to implement a completely separated Consumer application (derived from ndn::App), taking the existing one as a base for the implementation. This way you going to have full control on what is happening. </div><div><br></div><div>If the only functionality that you want is to send Interests and do not retransmit ones that timed out, you can try to use a consumer similar to DumbRequester from examples (examples/custom-apps/dumb-requester.h/cc): <a href="http://ndnsim.net/applications.html#dumb-requester">http://ndnsim.net/applications.html#dumb-requester</a></div><div><br></div><div>As for the sequence numbers. Consumer-derived apps make an assumption that you would send Interest in a specified namespace (/<a href="http://ucla.edu/alex/cv">ucla.edu/alex/cv</a>) with sequence numbers:</div><div><br></div>/<a href="http://ucla.edu/alex/cv/0">ucla.edu/alex/cv/0</a><br>/<a href="http://ucla.edu/alex/cv/1">ucla.edu/alex/cv/1</a><br>/<a href="http://ucla.edu/alex/cv/2">ucla.edu/alex/cv/2</a><br>/<a href="http://ucla.edu/alex/cv/3">ucla.edu/alex/cv/3</a><div>/<a href="http://ucla.edu/alex/cv/4">ucla.edu/alex/cv/4</a></div><div>...</div><div><br></div><div>(ConsumerZipfMandelbrot does not request sequentially, but still uses notion of sequence numbers.)</div><div><br></div><div>---</div><div>Alex</div><br><div><div>On Mar 12, 2013, at 2:07 PM, Chengyu Fan <<a href="mailto:chengyu@cs.colostate.edu">chengyu@cs.colostate.edu</a>> wrote:</div><br class="Apple-interchange-newline"><blockquote type="cite">Sorry, here is another question: Can I set the <span style="color:navy">AnswerOriginKind</span><span style="font-size:12px;line-height:14px"> </span>bit in ndnSIM?<br><br><div class="gmail_quote">On Tue, Mar 12, 2013 at 2:56 PM, Chengyu Fan <span dir="ltr"><<a href="mailto:chengyu@cs.colostate.edu" target="_blank">chengyu@cs.colostate.edu</a>></span> wrote:<br>

<div>I did not find an example which does the similar thing.
