I was wondering if there are any tools folks can recommend for testing the kernel to make sure the congestion avoidance code is operating correctly. For example the displaying of the congestion window as a function of time while undergoing convergence. For causing congestion I could modify a kernel to discard packets once in a while on a lab gateway and hit it with iperf. HP's netperf looks interesting. Any suggestions? -piet -- --- piet@bluelane.com
