i-perf report

Hi,

I am using i-perf to pump UDP traffic to our experimental network .
I am transmitting data at a speed of 7mbs for 300secs. The link speed
is 10mbs. The command I used is :

i-perf -u -c <i-perf server ip > -b 7m -t 300

The i-perf server is started at another end (different network)
using
i-perf -s -u

Now when the data transmission is finished , the server sends the
bandwidth statistics to the client. But when the statistics reaches
the client , the statistics become doubled .

Can anybody can put light on this issue ?

With Thanks

.
