It depends. There are some special tools for generating traffic, but it's
often good enough to start a simple download (FTP or HTTP) and look at the
provided rate. What do you want to measure exactly? Describe the situation
if you feel that FTP or HTTP wouldn't suffice.

Try 
http://www.citi.umich.edu/projects/qbone/generator.html

gen_send and gen_recv provide a testbed for UDP variable length packet
generation, and metrics of bandwidth and packet loss.

The only drawback I see is that the logfiles are not updated in a timely
fashion so that one could apply periodic Bronc or other graphing tools
for rapid visualization.

                         ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
repeat : put it somewhere in your path.  If you execute "echo $PATH" as
root in a terminal, you get the path where monitor.pl will search for
the program.  OR adapt monitor.pl and change time_ms.exe in
./time_ms.exe.
