I'm currently in the early planning stages for having something l= ike
this incorporated into the netperf-wrapper [1] testing tool. In the
meantime, you could look at either thrulay [2] (old and apparently
abandoned, but may work in one of its variants) as a measurement tool,
or tcpprobe [3] to output statistics that can (probably) tell you.
