[c-nsp] QOS testing traffic generator and reporter

[Yuri Bank]

Take a look at pktgen

It's part of the Linux kernel, and it is very easy to use. Most
distributions will have this installed as a module, so all you have to do is
load it ( modprobe pktgen ), and then define the traffic parameters (IP
ranges, port ranges, ToS, etc )....

It is a great tool for testing QoS. And as you mentioned, iperf is good too.
