end to end packet delay, packet loss and system throughput

[Ateeq]

Im using lena-simple-epc example and want to calculate end to end packet loss, delay and system throughput but not able to extract this information from the output files, i also get pcap files but invain. Can any one help me on which file i have to concentrate. ??

Thanks

Hi Ateeq

The LTE trace files can be used to get statistics on the E-UTRAN plane, e.g. access delay and system throughput at MAC/PDCP layer
You can work with FlowMonitor to get end-to-end statistics at network layer. There are examples and discussions in the mailing list for it.

[Ateeq]

Thanks I was already working on flow monitor now having an issue.

In my lena-simpe-epc example i have added this code and then i run example with (1 UE/eNodeB ) 1 eNodeB and with 2 eNodeB.

But not getting the throughput and packet loss when i use 2 ENodeB's.

these lines i added in the script.

  Simulator::Stop(Seconds(simTime));
//added new line for flow monitor
FlowMonitorHelper flowmon;
 Ptr<FlowMonitor> monitor;
 monitor = flowmon.Install(ueNodes);
monitor = flowmon.Install(remoteHostContainer);

  Simulator::Run();

  /*GtkConfigStore config;
  config.ConfigureAttributes();*/

//added new lines for flow monitor
 monitor->CheckForLostPackets ();
monitor->SerializeToXmlFile ("results.xml" , true, true );
Ptr<Ipv4FlowClassifier> classifier = DynamicCast<Ipv4FlowClassifier> (flowmon.GetClassifier ());
std::map<FlowId, FlowMonitor::FlowStats> stats = monitor->GetFlowStats ();

for (std::map<FlowId, FlowMonitor::FlowStats>::const_iterator iter = stats.begin (); iter != stats.end (); ++iter)
  {
  Ipv4FlowClassifier::FiveTuple t = classifier->FindFlow (iter->first);

          NS_LOG_UNCOND("Flow ID: " << iter->first << " Src Addr " << t.sourceAddress << " Dst Addr " << t.destinationAddress);
          NS_LOG_UNCOND("Tx Packets = " << iter->second.txPackets);
          NS_LOG_UNCOND("Rx Packets = " << iter->second.rxPackets);
          NS_LOG_UNCOND("Throughput: " << iter->second.rxBytes * 8.0 / (iter->second.timeLastRxPacket.GetSeconds()-iter->second.timeFirstTxPacket.GetSeconds()) / 1024  << " Kbps");
 NS_LOG_UNCOND("Packet loss= " << ((iter->second.txPackets-iter->second.rxPackets)*1.0)/iter->second.txPackets);
  }

  Simulator::Destroy();
  return 0;

I search more things and added more things for flow monitor output.

Conclusion:

Unable to get receive packet, throughput and packet loss detail when UE is communicating with the remote host.

Flow ID: 2 Src Addr 7.0.0.2 Dst Addr 1.0.0.2
Tx Packets = 11
Tx Bytes = 11572
Sum jitter = +0.0ns
Delay Sum = +0.0ns
Lost Packet = 0
Rx Bytes = 0
Rx Packets = 0
Throughput: -0 Kbps
Packet loss %= 1

It provide receive packet information only when it is communicating with same UE-UE IP.

For example:

Flow ID: 3 Src Addr 7.0.0.2 Dst Addr 7.0.0.2
Tx Packets = 11
Tx Bytes = 11572
Sum jitter = +0.0ns
Delay Sum = +0.0ns
Lost Packet = 0
Rx Bytes = 11572
Rx Packets = 11
Throughput: 90.4062 Kbps
Packet loss %= 0

Please tell me how can i fix this. Thanks

Please provide a test script. Most probably you have not configured the routing for remote host properly.

And the change was just this:

ueNodes.Create(1);

to

ueNodes.Create(numberOfNodes);

which is the original command in the lena-simple-epc. 

[muhammad attique Atta]

I

​ am getting the same issue after reverting this change.

But this is giving you fine results, what can be a issue? (ns3 version ? im currently using 3.20)​

Nice catch. No wonder it wasn't transmitting from one UE to another UE, there was only one !

I'll avoid to do easy jokes about Ateeq's signature. It would be like shooting on the red cross. It's unfair but it's still 100 points, like they say.

Cheers,

T.

I'm not getting the expected results as Kostantinos pasted earlier. What can i do....?

Try upgrading to ns-3.22 (or ns-3-dev, even better). I just ran the script and the output is identical to Kostantinos's one.

T.

[Konstantinos]

There has been a reported bug with FlowMonitor and LTE in ns-3.20, which has been fixed since then. 

So, using the latest ns-3 release, as Tommaso suggested solves your problem.

Thanks I have fixed this issue but bushes are all around... 

In short... When i try to increase only number of UE's in this example then i'm getting missing results.

But if i put UE and eNodeB's number same (one UE per eNodeB) then it is fine does not matter how im setting it up. 

For example: This work for me.

double numberOfNodes = 3;

.
.
enbNodes.Create(numberOfNodes);

ueNodes.Create(3);

 

This also work for me:

double numberOfNodes = 3;

.
.
enbNodes.Create(numberOfNodes);

ueNodes.Create(numberOfnodes);

But this is not working:

double numberOfNodes = 2;

.
.
enbNodes.Create(numberOfNodes);

ueNodes.Create(3);

I am not getting the TX and RX exact information of all the flows when i only increase the UE number.

for example: I use default eNodeB = 2 and increase UE = 3.

double numberOfNodes = 2;

.
.
enbNodes.Create(numberOfNodes);

ueNodes.Create(3);

Im getting bellow output for this case.

I want to increase only the users by setting the eNodeB's to the specific numbers. Please help me how can i only increase the UE (I tried different things but in vain).

[Konstantinos]

Please read the code more carefully and particularly the place where a UE is attached to the eNB.

130  // Attach one UE per eNodeB

131  for (uint16_t i = 0; i < numberOfNodes; i++)

132  {

133  lteHelper->Attach (ueLteDevs.Get(i), enbLteDevs.Get(i));

134  // side effect: the default EPS bearer will be activated

135  }

...

[Ateeq]

Yes, Got it... It works... Thanks again... 

enbNodes.Create(numberOfNodes);
ueNodes.Create(2);

.
.

// Attach one UE per eNodeB

    for (uint16_t i = 0; i < numberOfNodes; i++)

        {
                for (uint16_t j = 0; j < 2; j++)
{
                  lteHelper->Attach (ueLteDevs.Get(j), enbLteDevs.Get(i));

[Konstantinos]

This is not correct since you attach the same UE on multiple eNB or just all of them to the second eNB (I do not know exactly how two consecutive Attach will be interpreted) .

Please think before you write the code and study the API to find more suitable methods

[senthil kumar]

Hai Ateeq ,

I have same problem i want to use 1 eNB and 10 UE.. how can i do this?

for example

enbNodes.Create(numberOfNodes);   here numberOfNodes = 1 (eNB)
ueNodes.Create(10);

and i put your command but  it does not works..

[Konstantinos]

Please read the code you have written and understand each command you are writing.

You may have references of 'numberOfNodes' in other places refering to the number of UEs, but since UEs=10 and numberofnodes=1 that is not working!

[senthil kumar]

Hai Konstantinos,

Thanks for your help..i got same problem again

when i put numberOfNodes =1 and UE=10

it shows delay , throughput = 0,  like this

i want to use 1 eNB and 10 UEs

I have attached my script and flow monitor results.. can you help me?

[Konstantinos]

Hi Senthil,

Do not just copy&paste blindly code, modify parts that you see others do without understanding what you are doing and then ask others to debug your code!

I see problems in the mobility and UE-eNB attachment.

The second is explained in my reply to Ateeq.

[senthil kumar]

ok i got it ..thanks...
