TCPREPLAY is nice, but you have to have a copy of
traffic from something.  It can sometimes be
challanging to find and / or create the traffic you
wish to repeatedly simulate.

I used Spirent Avalanche and Reflector at a prior job.
 They are commercial and they are a bit pricey,
however they not only simulate traffic they can also
simulate specific server types and versions to
generate said simulated traffic.  Spirent can generate
all kinds of good, mal formed, and flat out bad
traffic types.  Another downside to that particular
package is that it tended to be a bit touchy in the
configuration.  We had a lot of issues with
"stability", however after buying the product
management never gave us money to actually attend
trainging so those stability issues may have been user
