Unfortunately the router's CPU is not powerful enough to fill a high-speed link; we had to deploy dedicated probes for NIL Monitor.

Also, using a server to solve network problems is soft. Real engineers are purists. ha ha ha ha ha......just kidding. Whatever works. I actually have a Java implementation for TTCP somewhere.

Doubly so for secure networks (and I mean properly secure, not enterprise or business networks). 2) if you want to test a given link that is between two towns in another country, using iperf isn't an option. You would break the links in between. 3) it's quick and dirty. See the bit about 'poor mans traffic generator'. Sometimes good enough is enough. Let’s see:

If you can ping a router, you know it's up. If you want to load test it, using something like iperf (http://sourceforge.net/projects/iperf/) is going to me much more useful, yah?
