Discard Routing Packets from flowmonitor

[OverPowered]

Hi,

 i have flow monitor code which is.

FlowMonitorHelper flowmon;

Ptr<FlowMonitor> monitor = flowmon.InstallAll(); 

Simulator::Run ();

monitor->CheckForLostPackets ();

Ptr<Ipv4FlowClassifier> classifier = DynamicCast<Ipv4FlowClassifier> (flowmon.GetClassifier ());

std::map<FlowId, FlowMonitor::FlowStats> stats = monitor->GetFlowStats ();

float txPacketsum = 0,

rxPacketsum = 0,

DropPacketsum = 0,

LostPacketsum = 0,

Delaysum = 0,

txBytessum = 0, 

rxBytessum = 0, 

First = 1,

s1 = 2.5,

dp = 0;

  for (std::map<FlowId, FlowMonitor::FlowStats>::const_iterator stats = flowStats.begin();

             stats != flowStats.end(); ++stats) {

            tempThroughput = stats->second.rxBytes * 8.0 / (stats->second.timeLastRxPacket.GetSeconds() -

                                                            stats->second.timeFirstTxPacket.GetSeconds()) / 1024;

            delay = stats->second.delaySum.GetSeconds();

            pdr = stats->second.txPackets / stats->second.rxPackets;

            dataset.Add((double) stats->first, (double) tempThroughput);

            dataset2.Add((double) stats->first, (double) delay);

            dataset3.Add((double) stats->first, (double) pdr);

        }

for (std::map<FlowId, FlowMonitor::FlowStats>::const_iterator i = stats.begin (); i != stats.end (); i++)

{

txBytessum += i->second.txBytes;

txPacketsum += i->second.txPackets;

rxPacketsum += i->second.rxPackets;

rxBytessum += i->second.rxBytes;

LostPacketsum += i->second.lostPackets;

DropPacketsum += i->second.packetsDropped.size();

Delaysum += i->second.delaySum.GetSeconds();

dataset.Add(First, ((rxBytessum * 8.0) / 1000) );

dp = i->second.txPackets - i->second.rxPackets - i->second.lostPackets;

First = i->first * s1;

}

plot.AddDataset (dataset);

plot2.AddDataset (dataset2);

plot3.AddDataset (dataset3);

std::cout << "\n\t ----------------RESULT-------------------\n\n ";

std::cout << "\t  All Tx Packets: " << txPacketsum << "\n";

std::cout << "\t  All Tx Bytes: " << txBytessum << "\n";

std::cout << "\t  All Rx Packets: " << rxPacketsum << "\n";

std::cout << "\t  All Rx Bytes: " << rxBytessum << "\n";

std::cout << "\t  All Lost Packets: " << LostPacketsum << "\n";

std::cout << "\t  All Drop Packets: " << dp << "\n";

std::cout << "\t  All Drop Bytes: " << DropPacketsum << "\n";

std::cout << "\t  Total Delay: " << Delaysum << "\n";

std::cout << "\t  Delay per Packet: " << Delaysum / txPacketsum << "\n";

std::cout << "\t  Packets Delivery Ratio: " << ((rxPacketsum * 100) / txPacketsum) << "%" << "\n";

std::cout << "\t  Throughput: " << (rxBytessum * 8.0) / 1024    << " Kbps\n";

std::cout << "\n" << endl;

std::cout << "\n\t ----------------THANKS-------------------\n\n\n ";

this code also count AODV. DSDV, OLSR packets also, which i dont want.

how can i discard routing packets.

Thanks 

Regards
