Poisson simulation parameters

$Exponential1 set rate_ 384Kb
$Exponential1 set packetSize_ 210
$Exponential1 set burst_time_ 500ms
$Exponential1 set idle_time_ 500ms
$Exponential1 attach-agent $udp1

Is this correct? need to check..hehe

I found a website in order to emulate the poisson process set the burst_time_ to zero.
