Testing Congestion Control Algorithms

[Karlis Laivins]

Hi,

I am currently working on a modification of TCP NewReno congestion control
algorithm. It seems that I have been able to write a working module.

Now, I am looking for a way to test the performance of the built-in
congestion control algorithms and the new algorithm. I have heard about the
NS-2 simulator, and I am trying to compile and configure it now, but that's
just a statistical tool (from what I hear) and the results are far from
reality (please correct me, if I am wrong).

Please recommend a tool or way I can test the performance of the congestion
control algorithm in a "real" environment (sender side - 2 Computers, one
connected to the wireless network, other to a wire, receiver - one PC,
running FTP server, both senders each sending a big file at the same time).
I would like to get comparable performance results from each of the
existing congestion control algorithm as well as the new one I have created
by modifying the NewReno algorithm.

Thank you in advance for your assistance.

Best Regards,
Karlis
