Re: Application/Traffic/CBR bug ?

Hi Federico,

I think the the graph generated  is reasonable.

at 5.0 the rate change to 10000 and at 6.0 it change to 1M again follow your
command.   $ns at 6.0 "$traffic set rate_ 1Mb"

I changed  your code  at line :
   $ns at 6.0 "$traffic set rate_ 1Mb" 
to 
   $ns at 6.0 "$traffic set rate_ 2Mb" 
and run ns again then the output graph is noticeble sharp at 6.0.

did I misunderstand your meaning?

Regards.
