Simulasi pertama dengan NS2

Topology yang digunakan adalah sebagai berikut :

Berhubung masih nobitol, jadinya masih script kiddies T_T

--------------------------------------------------------------

#Create a simulator object
set ns [new Simulator]

#Create a trace file
set mytrace [open out.tr w]
$ns trace-all $mytrace

#create a NAM trace file
set myNAM [open out.nam w]
$ns namtrace-all $myNAM
#Define a procedure finish
proc finish {} {
 global ns mytrace myNAM
 $ns flush-trace
 close $mytrace
 close $myNAM
 exec nam out.nam &
exit 0
}
#Create two nodes
set n0 [$ns node]
set n1 [$ns node]
set n2 [$ns node]
$n0 color blue
$n0 label "cnc1"
$n1 color red
$n1 label "cnc2"
$n2 color green
$n2 label "cnc3"
#Create a duplex link between the nodes
$ns duplex-link $n0 $n1 100Mb 5ms DropTail
$ns duplex-link $n1 $n2 54Mb 10ms DropTail
#Create a TCP agent
set tcp [new Agent/TCP]
$ns attach-agent $n0 $tcp
set sink [new Agent/TCPSink]
$ns attach-agent $n2 $sink
$ns connect $tcp $sink
$tcp set fid_ 2
#Create an FTP session
set ftp [new Application/FTP]
$ftp attach-agent $tcp
#Schedule events
$ns at 0.05 "$ftp start"
$ns at 60 "$ftp stop"
$ns at 61 "finish"
#start the Simulation
$ns run

Selamat Mencoba ^_^
