If a software based solution is OK, check out IxChariot, endpoints can be 
Windows, Linux, OS X, and Solaris. Used it years ago and was happy with it.

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

If you are looking to automate any of your testing, +1 Ixia if the box
is using the Agilent OS/Interface (I forget how they are marketing it
now).  In regards to automation, I recently heard the Spirent
interface was quite handy for generating scripts from GUI
interactions, but I have not used it myself.

HTHs,

The venerable mgen (http://cs.itd.nrl.navy.mil/work/mgen/) is another good 
option, provided you don't want lots of bandwidth.
It has some flexibility in scripting the flows it creates.

We have quite a number of companies using hardware from companies like Ixia
and Spirent - the key is to use tools that makes it easy to setup a testing
methodology without hiring a support staff. 

You can contact me directly for more information and how others like Cisco,
At&T, Vodafone and many more are doing this sort of testing.

It really depends on the product you are testing. If forwarding performance
is what you want to measure, you would do it with various routing table
sizes (starting small and ending with a global table). Packet size is also
something you should look at.

We could provide better suggestions if you tell us what your product is.

Probably more/more formal than you want, but:

And I think you may find that some of the vendor folks are active in the WG.

Re: flow generating tool

[jiaruchen]

Iperf(linux) and jperf(windows) does generate traffic flows. You simply set up 
sender/receiver and it'll generate traffic load. It can generate 10gig line 
rate unicast flows but multicast replication is limited because it is software 
based. 

Iperf/jperf however, is not as flexible or anywhere as feature rich and 
powerful as some of the other hardware solutions as mentioned earlier - ex: 
ixia, spirent etc.

Perhaps not a tool as in software, but clearly something that you might want
to have a look at : 

Ixia and Spirent devices ... Those are mostly used for applications like
generating different kind of traffic.

Sorry I missed your context.  YAF will generate flows (which is what I
thought you were asking) as it sees packets stream by, but it sounds
like you want something that puts traffic on the wire.

An old standby is:

  http://tcpreplay.synfin.net/

and of course there are commercial options.  Not sure how up to date
this is, but there are quite a few options listed here:

Thank you for the response, but this is a tool that examines data flows. I need 
a tool that generates data flows in order to test network equipment.
