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.
There is a setup called 'imunes' (from memory) that used the virtual stack
capabilities (VNET/VIMAGE) to give you a fully configurable test
network within a singe computer.
see http://imunes.tel.fer.hr/
I'm not sure if the CC stuff can be set up "per vnet" but if it can
then you could use that..
or do it yourself using vnet jails and dummynet for link
latency/throughput.
if Marko is around he may be able to tell you about the current state
of imunes.
Best Regards,
Karlis
