Dear all<br>
I just want to calculate the total number of received data packet on the<br>
consumer in the ndn-simple.cpp. I used the following code in which i used<br>
the callback function named Client as well as global variable r to count<br>
the number of packets.<br>
<br>
#include "ns3/core-module.h"<br>
#include "ns3/network-module.h"<br>
#include "ns3/point-to-point-module.h"<br>
#include "ns3/ndnSIM-module.h"<br>
<br>
namespace ns3 {<br>
<br>
int r;<br>
void Client(Ptr<const ndn::Data> d, Ptr<const ndn::App> app, Ptr<const<br>
ndn::Face> f)<br>
{<br>
std::cout<<"Total data packets recieved"<<r++<<endl;<br>
}<br>
<br>
<br>
<br>
<br>
<br>
int main(int argc, char* argv[]) {<br>
<br>
<br>
Config::SetDefault("ns3::PointToPointNetDevice::DataRate",<br>
StringValue("1Mbps"));<br>
Config::SetDefault("ns3::PointToPointChannel::Delay",<br>
StringValue("10ms"));<br>
Config::SetDefault("ns3::QueueBase::MaxSize", StringValue("20p"));<br>

nodes.Create(3);<br>
<br>

PointToPointHelper p2p;<br>
p2p.Install(nodes.Get(0), nodes.Get(1));<br>
p2p.Install(nodes.Get(1), nodes.Get(2));<br>
<br>
// Install NDN stack on all nodes<br>
ndn::StackHelper ndnHelper;<br>
ndnHelper.SetDefaultRoutes(true);<br>
ndnHelper.InstallAll();<br>
<br>

ndn::StrategyChoiceHelper::InstallAll("/prefix",<br>
"/localhost/nfd/strategy/multicast");<br>
<br>
// Installing applications<br>
<br>
// Consumer<br>
ndn::AppHelper consumerHelper("ns3::ndn::ConsumerCbr");<br>
// Consumer will request /prefix/0, /prefix/1, ...<br>
consumerHelper.SetPrefix("/prefix");<br>
consumerHelper.SetAttribute("Frequency", StringValue("10")); // 10<br>
interests a second<br>
auto apps = consumerHelper.Install(nodes.Get(0));<br>
// first node<br>
apps.Stop(Seconds(10.0)); // stop the consumer app at 10 seconds mark<br>
<br>
// Producer<br>
ndn::AppHelper producerHelper("ns3::ndn::Producer");<br>
// Producer will reply to all requests starting with /prefix<br>
producerHelper.SetPrefix("/prefix");<br>
producerHelper.SetAttribute("PayloadSize", StringValue("1024"));<br>
producerHelper.Install(nodes.Get(2)); // last node<br>
Config::Connect("/NodeList/0/ApplicationList/*/ReceivedDatas",<br>
MakeCallback(&Client));<br>
Simulator::Stop(Seconds(20.0));<br>
<br>
Simulator::Run();<br>
Simulator::Destroy();<br>
<br>
return 0;<br>
}<br>
<br>
// setting default parameters for PointToPoint links and channels<br>
