<div><span></span>Dear all:</div><div> Recently, I wonder about the <span style="font-family: ''; font-size: 10.5pt; line-height: 1.5; background-color: window;">expiry of PIT entry recorded in the PIT module, and I print the expiry in the Inrecord of each entry by adding print information in the "Forwarder::onIncomingInterset()" and move function "</span><span style="font-family: ''; font-size: 10.5pt; line-height: 1.5; background-color: window;">compare_InRecord_expiry" ahead to avoid error. I run the "</span><span style="font-family: ''; font-size: 10.5pt; line-height: 1.5; background-color: window;">./waf --run ndn-simple" successfully and redirect the output into a text file.</span></div><div><span style="font-family: "" microsoft="" yahei="" ui'";="" font-size:="" 14px;="" color:="" rgb(0,="" 0,="" 0);="" background-color:="" rgb(255,="" 255,="" 255);="" font-weight:="" normal;="" font-style:="" normal;text-decoration:="" none;'="">//+++++++++++++++++++++++++++++++++++++++<br>double tt = ns3::Simulator::Now().ToDouble(ns3::Time::S);<br>std::cout <<"==========Forwarder::onIncomingInterest==================" << interest.getName().toUri() << "\t" << m_pit.size() << std::endl;<br>auto it = m_pit.begin();<br>for(it = m_pit.begin(); it != m_pit.end(); it++)<br>{<br> pit::InRecordCollection::iterator lastExpiring = std::max_element(it->in_begin(), it->in_end(), &compare_InRecord_expiry);<br> time::nanoseconds time_s = lastExpiring->getExpiry()- time::steady_clock::now();<br> std::cout << tt << "\t" << it->getName().toUri() << "\t" << time_s << std::endl;<br>}<br>//+++++++++++++++++++++++++++++++++++++++</span></div><div><span style="font-family: ''; font-size: 10.5pt; line-height: 1.5; background-color: window;"> In general, the expiry should be a non-negetive value since it means the time interval to be expired. However, I find there are negetive values and huge positive values in the result file. As shown below fig. and I doubt the entry satisfied by Data is not clear timely, but I still cannot convince myself. </span></div><div><img src="cid:_Foxmail.1@e939d574-8164-c283-297b-f73a61d5eb9b" border="0"></div>
