How to Start IEEE 802.3 Ethernet Projects Using NS2

To create an IEEE 802.3 (Ethernet) project using NS2 (Network Simulator 2) has been includes their replicate of Ethernet networks to examine their performance and analyze parameter metrics like as throughput, collision, and delay. Below is a step-by-step guide:

Steps to Start IEEE 802.3 (Ethernet) Projects Using NS2

  1. Understand the Basics of IEEE 802.3 in NS2
  • What is IEEE 802.3 (Ethernet)?
    • A widely used LAN technology which works on CSMA/CD (Carrier Sense Multiple Access with Collision Detection) principles.
    • It delivers the wired communication through detailed frame formats, speeds, and media access control.
  • Ethernet Simulation in NS2:
    • NS2 supports Ethernet simulation with wired nodes and links.
    • It can collisions are replicate, broadcast delays, queue management, and different traffic model.
  1. Install NS2
  • Installation on Linux:

sudo apt-get update

sudo apt-get install ns2

  • Test installation:

ns

If % appears, NS2 is successfully installed.

  1. Define Your Ethernet Network Topology
  • Decide the structure of your Ethernet LAN:
    • Star Topology: Central switch/hub are connecting the several devices.
    • Bus Topology: Devices are connected in the single distribute the cable.
    • Tree Topology: The Hierarchical Ethernet LAN through switches.
  1. Create a Basic Ethernet Simulation

Here’s a simple IEEE 802.3 Ethernet simulation script in NS2:

Example Script

# Create a Simulator

set ns [new Simulator]

 

# Create Trace and NAM Files

set tracefile [open ethernet.tr w]

$ns trace-all $tracefile

set namfile [open ethernet.nam w]

$ns namtrace-all $namfile

# Define Nodes

set n0 [$ns node]

set n1 [$ns node]

set n2 [$ns node]

set n3 [$ns node]

# Create Links (Ethernet-specific delays and bandwidths)

$ns duplex-link $n0 $n1 10Mb 0.01ms DropTail

$ns duplex-link $n1 $n2 10Mb 0.01ms DropTail

$ns duplex-link $n2 $n3 10Mb 0.01ms DropTail

# Configure Traffic (TCP or UDP)

# Create TCP Agent

set tcp [new Agent/TCP]

$ns attach-agent $n0 $tcp

# Create TCP Sink

set sink [new Agent/TCPSink]

$ns attach-agent $n3 $sink

$ns connect $tcp $sink

# FTP Application

set ftp [new Application/FTP]

$ftp attach-agent $tcp

$ftp start

# Finish Procedure

proc finish {} {

global ns tracefile namfile

$ns flush-trace

close $tracefile

close $namfile

exec nam ethernet.nam &

exit 0

}

# Schedule Simulation End

$ns at 10.0 “finish”

# Run Simulation

$ns run

  1. Configure Ethernet-Specific Parameters
  • Link Speed: Alter the bandwidth for Ethernet standards such as:
    • 10 Mbps (10BASE-T)
    • 100 Mbps (Fast Ethernet)
    • 1 Gbps (Gigabit Ethernet)

$ns duplex-link $node1 $node2 100Mb 0.01ms DropTail

  • Propagation Delay: Realistic broadcast are replicate the delays:

$ns duplex-link $node1 $node2 1Gb 0.5ms DropTail

  • Collision Simulation: Use distributes the connection or hubs to replicate the CSMA/CD.
  1. Visualize the Simulation
  • Start the NAM file:

nam ethernet.nam

  • Monitor the packet flow, collisions, and queuing in the network.
  1. Analyze the Output
  • Trace File Analysis: Analyze the trace file (ethernet.tr) for:
    • Packet delivery
    • Throughput
    • Collision count
    • End-to-end delay
  • Parsing the Trace File: Use tools like AWK or Python to extract metrics.
  1. Enhance the Ethernet Simulation
  • Advanced Topologies: Enhance the further nodes, switches, or hubs in the topologies.
  • Traffic Variations: Replicate the various traffic sources for instance FTP, HTTP, and VoIP.
  • Queue Management: Research through kind of queue like DropTail, RED, or FQ.
  • Compare Performance: Estimate the various Ethernet standards for instance 10BASE-T, 100BASE-TX, 1000BASE-T.
  1. Experiment with Advanced IEEE 802.3 Scenarios
  • Collision Analysis:
    • Replicate the environment through high contention and calculate the collision rates.
  • Traffic Bottleneck:
    • Establish the high-volume traffic to monitor the congestion.
  • Latency Evaluation:
    • Calculate the latency through increasing number of nodes and congestion.
  • Switch vs. Hub:
    • Associate the performance of using the switches like as full-duplex) and hubs such as half-duplex.
  1. Document Your Project
  • Simulation Objectives: State what your goal to achieve for sample performance comparison, collision study.
  • Topology and Configuration: It has involves the details of nodes, connection, and congestion.
  • Results and Observations: The current results are throughput, delay, and collision analysis.
  • Tools: Use these tools Gnuplot or MATLAB to mark the graphs for visualizing metrics.

We clearly understood and get knowledge about how to install the ns2 simulation and how to deploy the IEEE 802.3 (Ethernet) for collision and network protocol has executed in ns2 simulator. For further inquiries about this project, a separate manual will be provided.
