Another method is to use a packet sniffer with appropriate capture filters, creating \
a stream that can be replayed.  Both the capture and playback are easy to implement \
with ethereal, and I'm sure other packet sniffers have similar capabilities.

An obvious advantage is that you are repeating a stream that actually occurred.  You \
can't get more real than that.  If you need to design and shape the traffic, however, \
this method won't help.  I find it especially useful to identify problems triggered \
by a particular data pattern.
