How to Begin Implement IEEE 802.3 Ethernet project in ns3

To stimulate the estimation of IEEE 802.3 Ethernet project using NS3 includes the replicate of wired local area network (LAN) by Ethernet as the transmission medium. The Ethernet is generally used in the network and NS3 tool has offers the robust components for replicate the behaviour.

Below is a detailed guide to help you start your project:

Steps to Begin Implementing a IEEE 802.3 Ethernet projects using ns3

1. Understand IEEE 802.3 Ethernet

• Key Features:
  • Ethernet is a wired LAN protocol for described the below steps in IEEE 802.3.
  • It performs using the MAC (Media Access Control) and PHY (Physical Layer) layers.
  • It helps for different speeds such as 10 Mbps, 100 Mbps, 1 Gbps.
  • Uses the Carrier Sense Multiple Access by Collision Detection (CSMA/CD) for assign the medium.
• Common Use Cases:
  • LAN design and analysis.
  • Performance of estimation for Ethernet protocols and setting.

2. Set up NS3 Environment

• Download and install NS3.
• Familiarize by components such as:
  • CSMA Module: Used for replicate the Ethernet such as wired LAN.
  • Internet Module: Intended for increase the IP-layer functionality.
  • Applications Module: Designed for creating congestion.

3. Define Project Objectives

• Sample of what we can replicate:
  • Packet transmission and collision for finding the Ethernet.
  • Examine the congestion for various speeds of Ethernet.
  • Network topology affects the Performance.
  • Estimation the Quality of Service (QoS) in Ethernet networks.

4. Design the Ethernet Topology

• Nodes:
  • The nodes are signifying the computers or devices for the Ethernet LAN.
• Channels:
  • Make use the channels for CSMA of wired Ethernet communication.
• Traffic:
  • Estimate the congestion designs for using the applications like as TCP, UDP and HTTP.

5. Basic Example of IEEE 802.3 Ethernet Simulation

Here’s a basic tool NS3 script for replicate an Ethernet LAN by five nodes:

#include “ns3/core-module.h”

#include “ns3/network-module.h”

#include “ns3/internet-module.h”

#include “ns3/csma-module.h”

#include “ns3/applications-module.h”

using namespace ns3;

int main(int argc, char *argv[]) {

CommandLine cmd;

cmd.Parse(argc, argv);

// Create nodes

NodeContainer nodes;

nodes.Create(5); // 5 Ethernet nodes

// Set up CSMA channel

CsmaHelper csma;

csma.SetChannelAttribute(“DataRate”, StringValue(“100Mbps”));

csma.SetChannelAttribute(“Delay”, TimeValue(NanoSeconds(6560)));

// Install CSMA devices

NetDeviceContainer devices = csma.Install(nodes);

// Install Internet stack

InternetStackHelper stack;

stack.Install(nodes);

// Assign IP addresses

Ipv4AddressHelper ipv4;

ipv4.SetBase(“10.1.1.0”, “255.255.255.0”);

Ipv4InterfaceContainer interfaces = ipv4.Assign(devices);

// Create a server application on node 0

uint16_t port = 9; // Well-known echo port number

UdpEchoServerHelper echoServer(port);

ApplicationContainer serverApps = echoServer.Install(nodes.Get(0));

serverApps.Start(Seconds(1.0));

serverApps.Stop(Seconds(10.0));

// Create a client application on node 4

UdpEchoClientHelper echoClient(interfaces.GetAddress(0), port);

echoClient.SetAttribute(“MaxPackets”, UintegerValue(10));

echoClient.SetAttribute(“Interval”, TimeValue(Seconds(1.0)));

echoClient.SetAttribute(“PacketSize”, UintegerValue(1024));

ApplicationContainer clientApps = echoClient.Install(nodes.Get(4));

clientApps.Start(Seconds(2.0));

clientApps.Stop(Seconds(10.0));

// Run simulation

Simulator::Run();

Simulator::Destroy();

return 0;

}

6. Expand the Simulation

• Network Topology:
  • Improve the further nodes and replicate the topology for star, bus, or hybrid topologies.
• Traffic Patterns:
  • It replicates the design for varied congestion for sample TCP and UDP flows.
• Collision Detection:
  • Establish the congestion intensity for investigate the collision rates of backoff mechanisms.
• QoS:
  • Improve the prioritization of congestion using the applications such as Video Streaming or VoIP.

7. Performance Metrics

• Throughput:
  • Calculate the throughput for percentage of successful data delivery.
• Latency:
  • From source to destination for estimate the packet delay.
• Collision Rate:
  • Examine the frequency for collisions below various congestion loads.
• Packet Loss:
  • It measures the rate of lost packets.

8. Advanced Features

• Energy Efficiency:
  • The energy efficiency for replicate the power-saving modes for Ethernet.
• Link Aggregation:
  • For replicate the environment by several connections are aggregated for the bandwidth improved.
• Fault Tolerance:
  • It validates the network for behavior below the connection or node failures.
• Integration with Higher Protocols:
  • Enhance the IP address or transport-layer protocols designed for end-to-end communication.

9. Visualization and Analysis

• We can use the tools like NetAnim for envision the Ethernet packet flows.
• Investigate the data logs for using the Python, MATLAB, or envision for other tools in estimate the performance.

10. Extensions

• Virtual LAN (VLAN):
  • It replicates the VLAN for setting and validates the segregation among their networks.
• Traffic Control:
  • Apply the queuing mechanisms such as FIFO, CoDel, or RED.
• Security:
  • It replicates the intrusion detection or packet filtering mechanisms.
