Measuring throughput for a UDP app

[MProkop]

Im working with inetmant trying to setup a small VANET. Currently my
nodes contain a simple UDP app, pretty much send messages to a single
node every X seconds. What I want to do is try to measure throughput
to the application. Can anyone suggest an easy way of doing this?

[Rudolf Hornig]

If your network has DatarateChannels (i.e. ethernet) you can measure the throughput on the channles by enabling the built-in statistics on the DatarateChannlel. Put 

**.channel.throughput.result-recording-modes = all

in your ini file

I tried putting that in there and I received no extra results in
either my VEC or SCA files. I am fairly new to Omnet so maybe I am
misunderstanding you or maybe I am doing something wrong.

Heres is my NED file for the hosts, maybe this will help....

Ah ok, you are simulating a wireless scenario :) The mentioned line turns on the logging ONLY on DatarateChannels (like ethernet etc.). If you want to measure the thruput inside the module, you have to modify module's ned file and exchange the IdealChannel with DatarateChannel. YOu should have something like this:

       udp.appOut++ --> DatarateChannel --> udpapp.udpIn;

(keep the dataratechannel's paramaeters (delay and datarate) at the default 0)

Rudolph,

Thank you very much for the advice. I will give it a shot tonight or
tomorrow and let you know how I make out.

I added the following line to my NED file:
udpapp.udpOut --> DatarateChannel --> udp.appIn++;

It seemed to work and I am getting a throughput value! Thanks for the
help. I am probably not looking hard enough at Omnet but do you know
what units that measurement is in? I have a few simulations running at
the moment so I will check when they complete in a little while.

May I use this parameter in PPP links? Can you please send me an
example for extension of PPP channel called "Link1"?

Thanks!

[MProkop]

This might work, I am not really sure. All I did was replace the
standard connection between my UDP and Application layers with the
DataRateChannel and it worked. Give it a try and let me know how you
make out!

hello, can you help me, to show  throughput chanel  on Vector?
because if i use 

**.channel.throughput.result-recording-modes = all

 just only  Scalar. thanks

Mr.Rudolf

How if I get error in NED NA_AdhocHost.NED not in StandartHost.NED?

        networkLayer.igmpOut --> thruputMeter_rx.in;
        networkLayer.igmpIn <-- thruputMeter_tx.out;

can you help me why I have error??

Thanks you before...

That was an amazing advice thank you so much.

I have some problems on showing performance metrics

1- ın rip, ospf example files, I want to get end-to-end delay, throughput like basically performance metrics.

But in rip/simpletest I saw e-t-e delay. However I could not get e-t-e delay in rip/dynamictest.

2- in ospf, in fulltest file, I got e-t-e- delay bur in simple test I did not.

I am very confused.

Please help.
