Yes you can in Linux.

The Software Name is OMNET++ 4.6 or Higher Version.

Exaple Solution:

void Txc::handleMessage(cMessage *msg) { // ... simtime_t eed = simTime() - msg->getCreationTime(); }

simTime() returns current simulation time.

Thank you very much to all of you,

Is it possible to calculate the end-to-end delay and the overhead using tcpdump log file?

Hi Shujat Ali

Many thanks for your answer, it is much appreciated.

you are right, it is a time-consuming and complex process to analyse a tcpdump log file, do you know any tool to perform these calculations?

I am wondering if I can write a script to analyse the log file.

How can I get the end-to-end delay and overhead using Wireshark for both TCP and UDP traffic?

Hi Shujat Ali

I am really grateful to you,

There is a TCP Stream Graphs in Wireshark but I can not find it for UDP.

Also, I have got through the below link to Detect TCP Delays

Any suggestion for UDP traffic, please
