How To Run CLASSIFIER PORT.H Packages in Ns2

How To Install CLASSIFIER PORT.H Packages in Ns2

To Import Classifier-Port.H Packages in Ns2 tool we are ready with all the needed tools and resources, get on time support with best outcomes from us. Packets are directed according to port numbers by the classifier-port.h. Incoming packets are routed to the appropriate application or protocol according to the source or destination port number listed in the packet header thanks to the Port Classifier, which acts as a packet-sorting mechanism at the transport layer. Methods and properties for preserving port mappings and packet forwarding rules are defined in the classifier-port.h file. In network simulations involving protocols like TCP and UDP, where various port numbers represent various services or applications, this mechanism is especially crucial. In the simulation environment, the classifier makes sure that packets intended for a specific port are routed to the right application instance.

Steps required for the installation of Classifier-port.h.

PRE-REQUISITES:

Fresh installation of Ubuntu 16.04 LTS:

2.NS-2.35 Installation:

Screenshot:

Here, Percentage (%) symbol Denotes the successful installation of the NS 2.35.

HEADER FILE VERIFICATION:

Locate to the ns-2.35 folder:

2.Create the Main.tcl file in the scratch folder:

Next we need to create the Main.tcl file by using text editor in the ns-2.35 folder.

Screenshot:

Next we need to paste the below code to the Main.tcl file and save the file in the ns-2.35 folder.

Code:

set ns [new Simulator]

set tracefile [open out.tr w]

set namfile [open out.nam w]

$ns trace-all $tracefile

$ns namtrace-all $namfile

set classifier [new Classifier/Port]

proc finish {} {

global ns tracefile namfile

$ns flush-trace

close $tracefile

close $namfile

exec nam out.nam &

exit 0

}

set n0 [$ns node]

set n1 [$ns node]

set n2 [$ns node]

set n3 [$ns node]

$ns color 0 red

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

$ns duplex-link $n1 $n2 1Mb 10ms DropTail

$ns duplex-link $n2 $n3 1Mb 10ms DropTail

set tcp [new Agent/TCP]

$ns attach-agent $n0 $tcp

set sink [new Agent/TCPSink]

$ns attach-agent $n3 $sink

$ns connect $tcp $sink

set ftp [new Application/FTP]

$ftp attach-agent $tcp

$ns at 0.5 “$ftp start”

$ns at 4.5 “$ftp stop”

$ns at 5.0 “finish”

$ns run

Screenshot:

3.Open the Terminal:

Next, we need to launch the terminal by right clicking the mouse in the ns-2.35 location.

4.NS-2.35 Configuration && Building Process:

Next, we need to configure and build the ns-2.35 folder to make the Created files need to work in ns-2.35 configuration.

Command: “./make”

Screenshot:

Here, NS-2.35 Building process completed successfully.

5.Importing Classifier-port.h:

Here we imported the Classifier-port.h header file code indirectly accessed the Classifier-port class used in the Tcl script that we had highlighted lines that Classify packets based on ports and determines where in the packet the classifier starts its inspection in this network example program. Here we highlighted the code line that highlighted which is internally accessed Classifier-port.h, we will show class file that used in this code via Classifier folder.

Screenshot:

Here we will show the header file by opening Classifier-port.h file to show the class or function imported from the Classifier-port.h in the example code. This Tcl Script Line Classify packets based on ports and determines where in the packet the classifier starts its inspection in this network example program.

Screenshot:

6.Executing the Example Program for Classifier-port Header:

Then we need to run the Example program for Classifier-port Header to view output of the program.

Command: “./ns Main.tcl”

Screenshot:

Here we shown the output of the example program by using Classifier-port.h.

Screenshot:

In the NS 2.35 Simulation Example Program, the Classifier-port.h Header file is successfully imported. We possess all the essential tools and resources to support you at the right moment.
