Any idea how to stress test our bandwidth?

[jay alvarez]

I hope you don't mind my asking this here.

I'm working in an ISP right now. We are using mrtg for
each client connected to us. They can view their mrtg
statistics. Their way to the internet is to us. Say a
client connects to us via E1, they are guaranteed of
2.048Mbps because our uplink to the Internet is more
than the total of all the clients link's bandwidth
that are connected to us. Now one client wants to make
sure that they will be able to reach their guaranteed
bandwidth through the mrtg graphs. If we transfer huge
data from their site only up to us, we can
theoretically stress out their bandwidth. However,
they want to try increasing their consumption and see
for their self if they will reach the desired
bandwidth if they are actually connecting to any site
in the Internet, outside our network. Running iperf
from their site to us doesn't seem to reflect to the
MRTG. Any idea how to explain this to our client?


Thank you very much for your help
