flow generating tool

The test plan you use depends upon what you want to test - raw pps throughput, route convergence time, qos performance, etc.
We use Exfo (http://www.exfo.com) testers working to a mac-swap loopback for commissioning testing of Ethernet access circuits, looking at the usual loss/throughput/latency/jitter metrics and burst size.
When checking out new equipment in the lab we also use scapy scripts (http://www.secdev.org/projects/scapy/) to look at things like Ethertype and L2CP transparency.

Does anyone follow a network performance testing methodology, using hardware from companies like ixia/spirent?

I know that basic testing is typically done for validation of configs, but i assume other issues would make themselves apparent when pushed to these higher loads.

thoughts/comments?

Thanks
