The Fair Queuing (FQ) algorithm is designed to provide equitable bandwidth distribution among various network flows. The implementation of this algorithm is found in the fq.cc file, which outlines the process for managing packets from different flows to ensure a balanced allocation of bandwidth. By assigning each flow an equal portion of the network link, the algorithm prevents any individual flow from dominating the available bandwidth. The primary functions within fq.cc involve overseeing multiple queues, scheduling packets according to flow weights, and facilitating efficient packet transmission. Additionally, it manages flow classification and the enqueuing and dequeuing of packets to uphold fairness among competing network streams. The FQ algorithm enhances fairness, minimizes delays, and mitigates congestion in environments with numerous active flows. Through the TCL script, users can indirectly control the behavior and configuration of the FQ algorithm. They can enable or modify Fair Queuing for designated network links or nodes using specific TCL commands, eliminating the need to directly engage with the C++ code in fq.cc. This connection between the TCL interface and the C++ implementation allows for smooth integration and application of the FQ algorithm in simulations.

PRE-REQUISITES:

Fresh installation of Ubuntu 16.04 LTS:

Screenshot:

2.NS-2.35 Installation:

Screenshot:

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

Screenshot:

HEADER FILE VERIFICATION:

Locate to the ns-2.35 folder:

Screenshot:

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

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]

set n4 [$ns node]

set n5 [$ns node]

$ns color 0 green

# Create a duplex link between the nodes with FQ queue management

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

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

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

$ns duplex-link $n3 $n4 1Mb 10ms FQ

$ns duplex-link $n4 $n5 1Mb 10ms FQ

set tcp [new Agent/TCP]

$ns attach-agent $n0 $tcp

set sink [new Agent/TCPSink]

$ns attach-agent $n5 $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.

Screenshot:

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 Fq.cc:

Here we imported the Fq.cc header file code indirectly accessed the FQ class used in the Tcl script that we had highlighted lines that creates a bidirectional (duplex) link between nodes $n0 to $n5 with a bandwidth of 1 Mbps and a delay of 10 ms by using FQ Queue Management Algorithm in this network example program. Here we highlighted the code line that highlighted which is internally accessed Fq.cc, we will show class file that used in this code via Queue folder.

Screenshot:

Here we will show the header file by opening Fq.cc file to show the class or function imported from the Fq.cc in the example code. This Tcl Script Line creates a bidirectional (duplex) link between nodes $n0 to $n5 with a bandwidth of 1 Mbps and a delay of 10 ms by using FQ Queue Management Algorithm in this network example program.

Screenshot:

6.Executing the Example Program for Fq Header:

Then we need to run the Example program for Fq Header to view output of the program.

Command: “./ns Main.tcl”

Screenshot:

Here we shown the output of the example program by using Fq.cc.

Screenshot:

In the NS 2.35 Simulation Example Program, the Fq.cc Header file is successfully imported.
