This app will receive Interests, record them and then simply further forward them. Once the data packet is received, you can delete the Interest from your queue. </div><div class=""><br class=""></div><div class="">Another way to do that (with less flexible access probably) is to hack NFD directly and add an std::vector object or something as an attribute to the Forwarder class:</div><div class=""><br class=""></div><div class=""><a href="https://github.com/named-data-ndnSIM/NFD/blob/NFD-0.6.0-ndnSIM/daemon/fw/forwarder.cpp" class="">https://github.com/named-data-ndnSIM/NFD/blob/NFD-0.6.0-ndnSIM/daemon/fw/forwarder.cpp</a></div><div class=""><a href="https://github.com/named-data-ndnSIM/NFD/blob/NFD-0.6.0-ndnSIM/daemon/fw/forwarder.hpp" class="">https://github.com/named-data-ndnSIM/NFD/blob/NFD-0.6.0-ndnSIM/daemon/fw/forwarder.hpp</a></div><div class=""><br class=""></div><div class="">Hope that this helps,</div><div class=""><br class=""></div><div class=""><div class="">
