How to Start IPv4 Protocols Projects using OMNeT++

To stimulate an IPv4 Protocols project using OMNeT++ has contains the replicating a network transmission using the IPv4 protocol suite. This project can be range from the basic IP packet routing we advanced environment such as Quality of Service (QoS), congestion control, or IPv4 interoperability through other protocols.

Here’s how to get started IPv4 Protocols Projects using OMNeT++:

Steps to Start IPv4 Protocols Projects using OMNeT++

  1. Understand the Scope of IPv4 Projects
  • Focus Areas:
    • The IPv4 packet routing and forwarding the specific area.
    • Dynamic and static routing protocols such as RIP, OSPF.
    • Address resolution (ARP) and subnetting.
    • QoS or congestion prioritization.
    • Interoperability with IPv6.
  • Examples of IPv4 Projects:
    • Replicating the IPv4 routing in a simple network.
    • Enhance the QoS policies we prioritize the IPv4 traffic.
    • Examine the effect of subnetting on packet routing.
  1. Set Up OMNeT++
  • Install OMNeT++:
  • Install INET Framework:
    • INET has contains the IPv4 modules and routing protocols.
    • Clone or download INET from the INET GitHub repository.
    • We compile and integrate INET through OMNeT++.
  1. Create a New OMNeT++ Project
  • Open OMNeT++ IDE.
  • Create a New Project:
    • Go to File > New > OMNeT++ Project.
    • Name the project such as IPv4ProtocolProject.
  • Link the project to the INET framework:
    • Right-click on the project, go to Properties > Project References, and select INET.
  1. Define the Network Topology
  • Build a .ned file we model a network using IPv4:
    • Sample for a basic topology:

network IPv4Network {

submodules:

router: Router {

@display(“p=200,200”);

}

host1: StandardHost {

@display(“p=100,300”);

}

host2: StandardHost {

@display(“p=300,300”);

}

connections allowunconnected:

host1.pppg++ <–> router.pppg++;

host2.pppg++ <–> router.pppg++;

}

  1. Configure IPv4 in omnetpp.ini
  • Enable IPv4 Addressing:
    • Allows the IPv4 addresses and setting the routing table:

[General]

network = IPv4Network

sim-time-limit = 100s

*.host1.ipv4.address = “192.168.1.1”

*.host2.ipv4.address = “192.168.1.2”

*.router.ipv4.address = “192.168.1.254”

*.router.routingTable.staticRoutes = “192.168.1.0/24 via pppg0”

  • Dynamic Routing:
    • Enable protocols like RIP or OSPF:

*.router.routingProtocol = “RIP”

  1. Simulate Traffic
  • Improve the application-layer traffic we validate the IPv4 packet delivery:

*.host1.applications[*].typename = “UdpBasicApp”

*.host1.applications[0].destAddress = “192.168.1.2”

*.host1.applications[0].startTime = 5s

  1. Implement Custom IPv4 Logic
  • Extend IPv4 Modules:
    • Build a alter module in C++ if necessary, like as altered the Routing Table or Network Layer.
    • Estimate the advanced features such as load balancing, congestion control, or QoS policies.
  • Example: Add QoS Policies:
    • Prioritize the traffic based on application or packet type.
  1. Run and Debug the Simulation
  • Run the Simulation:
    • Follow on the packet routing and delivery in the replication environment.
  • Debugging:
    • Ensure the complete logging for IPv4 congestion and routing:

*.router.ipv4.verbose = true

  1. Analyze Performance
  • Metrics to Measure:
    • Packet delivery ratio.
    • End-to-end delay.
    • Routing table convergence time.
  • Used their performance OMNeT++’s built-in tools or export results to Python or MATLAB for visualization.
  1. Extend the Project
  • Advanced Features:
    • Subnetting and VLAN setting.
    • Congestion for engineering through IPv4.
    • Hybrid IPv4/IPv6 interoperability.
  • Large-Scale Scenarios:
    • Replicate the large networks through several routers and hosts.
  • Security:
    • Improve the security calculate like as firewalls or packet filtering.

Example Project: Subnetting and Dynamic Routing

  1. Build a network with several subnets.
  2. Ensure the dynamic routing using RIP or OSPF.
  3. Replicate and calculate the performance for packet delivery across subnets.
