Even i define the loss rate as 10%, 15% or 20% or more, I cannot see that kind of packet loss in simulations. For example, I am measuring the number of TCP packet sent from sender, number of TCP packets received at receiver and number of ACK packets at the sender. But the difference between the number of TCP packet sent from sender and the number of received TCP packets at receiver are not so much as defined in the loss rate. I was expecting that if I sent 1000 TCP packets and if I define the loss rate as %10, 100 TCP packets should be lost. But I cannot see this result in my simulation. In my simulaiton the packet losses about 1 %. My error model is as below: $ns_ node-config -IncomingErrProc losses_module -OutgoingErrProc losses_module proc losses_module {} { set loss_module [new ErrorModel] $loss_module set rate_ 0.10 $loss_module unit pkt return $loss_module } If anyone has an idea, i will deeply appreciate it. Thanks in advance, Semra ###################################################################### Dikkat: Bu elektronik posta mesaji kisisel ve ozeldir.
