Problem with UDP simulation

[Vipul Chaudhary]

I have created the scenario of udp users and attackers by modifying leodos.tcl

1. Replace "set agUsrSend($i) [new Agent/TCP/Newreno]" with "set agUsrSend($i) [new Agent/UDP]"

2. Replace "set apUsrSend($i) [new Application/FTP]" with "set apUsrSend($i) [new Application/Traffic/CBR]"

3. Replace "set apUsrSend($i) [new Application/Telnet]" with "set apUsrSend($i) [new Application/Traffic/Exponential]"

4. Add the following lines of code after "$agUsrSend($i) set packetSize_ $pam(ur_ps)":

if { $pam(ur_app)==0} {

  $apUsrSend($i) set burst_time_ 500ms

  $apUsrSend($i) set idle_time_ 500ms

  $apUsrSend($i) set rate_ 100k

}

if { $pam(ur_app)==1} {

  $apUsrSend($i) set rate_ 64Kb

  $apUsrSend($i) set random_ 1

}

now running the simulation shows that the attackers are not sending anything anymore why is this happening???????????

output:
