Simulating and getting congestion window plot in NS3

[Michał Cichecki]

Hello

I have to simulate the TCP protocol and get the congestion window plot. I've tried simulating the traffic-control.cc but I only got the .pcap file. What file from examples is the best to simulate and to get what I want. Moreover is there any way to slighly change the TCP algorithm (setting the cwnd and ssh_thresh) using the example files?

Hi,

Please refer to the tutorial. There is a tutorial example on congestion tracing and plotting.

There are different flavors of TCP which have an impact on cwnd and ssh_thresh. You can compare them (example provided in ns-3 codebase)

Regards,

Thanks for reply. Could you specify the example of congestion tracing? Which .cc file is it? I could not find it.

Please read the tutorial. It explains it.

This one? https://www.nsnam.org/docs/release/3.9/tutorial/tutorial_31.html

This is not the correct version for the tutorial.

Please use the one corresponding to the ns-3 release you are using.
