Hi Zakrai,<br>
1.a) How to calculate the total of entries in the CS at each second of the<br>
simulation time?2) Similarly, is there any way to obtain the number of entries in the PIT<br>
by time?<br>
To get PIT and CS size (number of entries), her a simple code:<br>
void printPitCSSize(){<br>
? auto currentNode = ns3::NodeList::GetNode(ns3::Simulator::GetContext());<br>
? auto& CurrNodePit = currentNode->GetObject<ndn::L3Protocol>()->getForwarder()->getPit();<br>
? auto& CurrNodeCS = currentNode->GetObject<ndn::L3Protocol>()->getForwarder()->getCs();<br>
? std::cout << "PIT number of entries: " << CurrNodePit.size() << " | CS number of stored packets: " <<? CurrNodeCS.size();<br>
}<br>
to get that information at every specific time, you can schedule calling printPitCSSize() function using ns3::Simulator::Schedule().<br>
<br>
1.b) If I use the CS tracer and count the number of cache hits at every second, does this give the number of entries at that time?<br>
No. Cache hits do not express the total number stord packets in the cache. Cache hit only indicates the case that a request has been successfully satisified from the node's local cache. Assume that there are 10 stored packets in the cache, at specific time, 2 requests have been received and satisifed from the local cache, in this case the cache size is 10 while the cache hits is 2.? <br>
<br>
I hope it helps.<br>
Best regards,Hussein <br>
<br>

Dear members,<br>
<br>
I have 2 questions about the size of the CS and the PIT:<br>
<br>
1) How to calculate the total of entries in the CS at each second of the<br>
simulation time? If I use the CS tracer and count the number of cache hits<br>
at every second, does this give the number of entries at that time?<br>
<br>
2) Similarly, is there any way to obtain the number of entries in the PIT<br>
by time?<br>
<br>
Regards,<br>
Zakaria<br>
