Study and installation of Network Simulator. Modify the same example such that node n0 sends data to n1 - Computer Networks | TCL

#Save File as .tcl

#OS - Linux

#File Execution - Any Linux Terminal

#Step:1 - Take New Simulator, Open it and how to execute

set ns [new Simulator] 

set nf [open out.nam w]

$ns namtrace-all $nf

proc finish {} {

            global ns nf

            $ns flush-trace

            close $nf

            exec nam out.nam &

            exit 0

}

#step:2 - Two Nodes, one link

set n0 [$ns node]

set n1 [$ns node]

$ns duplex-link $n0 $n1 1Mb 10ms DropTail

#step 3 - Sending Data

#Create a UDP agent and attach it to node n0

set udp0 [new Agent/UDP]

$ns attach-agent $n0 $udp0

# Create a CBR traffic source and attach it to udp0

set cbr0 [new Application/Traffic/CBR]

$cbr0 set packetSize_ 500

$cbr0 set interval_ 0.005

$cbr0 attach-agent $udp0

set null0 [new Agent/Null] 

$ns attach-agent $n1 $null0

$ns connect $udp0 $null0

$ns at 0.5 "$cbr0 start"

$ns at 4.5 "$cbr0 stop"

$ns at 5.0 "finish"

$ns run
