How can I calculate end-to-end delay and overhead in SDN? Is there any tool to do that in Linux?
I am using docker containers as OVS and ONOS controller.
any suggestion would be appreciated
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
