How to Start Open Shortest Path First Projects using OMNeT++

To create an Open Shortest Path First (OSPF) project using OMNeT++ has includes the replicating for a network in which the OSPF routing protocol dynamically measures the minimum path among nodes. OMNeT++ through the INET Framework helps for the OSPF execution, for creating it easier and examine the OSPF-based networks.

Here’s a step-by-step guide to start your project:

Steps to Start Open Shortest Path First Projects using OMNeT++

  1. Understand OSPF
  • Key Features of OSPF:
    • Link-state routing protocol designed for dynamic routing.
    • Used the Dijkstra’s procedure and we measure the minimum path.
    • Classifies the routers for regions into a large-scale network.
    • It helps for the load balancing and hierarchical routing.
  • Use Cases:
    • Internet service offers the networks.
    • Enterprise the networks through several subnets.
  1. Set Up OMNeT++
  • Install OMNeT++:
  • Install INET Framework:
    • INET has involves the OSPF modules and network-layer support.
    • Clone or download the INET framework from the INET GitHub repository.
    • We compile and incorporate INET through OMNeT++.
  1. Create a New OMNeT++ Project
  • Open OMNeT++ IDE.
  • Build a New Project:
    • Go to File > New > OMNeT++ Project.
    • Name the project for instance OSPFProject.
  • Connection the project to the INET framework:
    • Right-click the project, go to Properties > Project References, and check INET.
  1. Design the Network Topology
  • Build a .ned file to model a network through several routers and hosts:

network OSPFNetwork {

submodules:

router1: Router {

@display(“p=100,200”);

}

router2: Router {

@display(“p=300,200”);

}

router3: Router {

@display(“p=500,200”);

}

host1: StandardHost {

@display(“p=100,400”);

}

host2: StandardHost {

@display(“p=500,400”);

}

connections allowunconnected:

router1.pppg++ <–> router2.pppg++;

router2.pppg++ <–> router3.pppg++;

router1.pppg++ <–> host1.pppg++;

router3.pppg++ <–> host2.pppg++;

}

  1. Configure OSPF in omnetpp.ini
  • Enable OSPF on routers:

[General]

network = OSPFNetwork

sim-time-limit = 100s

*.router*.hasOspf = true

*.router*.ospf.routerId = “auto”

*.router*.ospf.areaId = “0.0.0.0”

*.router*.ospf.linkCost = 1

*.router*.ospf.enableHello = true

  • Assign IP addresses to hosts and routers:

*.host1.ipv4.address = “192.168.1.2”

*.host2.ipv4.address = “192.168.1.3”

*.router1.ipv4.address = “192.168.1.1”

*.router2.ipv4.address = “192.168.2.1”

*.router3.ipv4.address = “192.168.3.1”

  1. Add Traffic for Testing
  • Build a congestion among the hosts to monitor the OSPF behaviour:

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

*.host1.applications[0].destAddress = “192.168.1.3”

*.host1.applications[0].startTime = 10s

  1. Simulate and Debug
  • Run the Simulation:
    • Follow on the OSPF message alter the routing table bring up-to-date in the replication.
  • Enable Debugging:
    • Used the ensure for verbose logging and we track the OSPF operations:

*.router*.ospf.verbose = true

  1. Analyze Performance
  • Metrics to Measure:
    • OSPF routing convergence time.
    • End-to-end delay for packet delivery.
    • Connection utilization and routing effectiveness.
  • Used the metrices perform as OMNeT++’s built-in analysis tools or export data for more run in Python or MATLAB.
  1. Extend the Project
  • Simulate Failures:
    • Establish the connection or node failures we validate the OSPF’s ability to recompute the routes dynamically.
  • Add Multiple Areas:
    • Split the network into several OSPF regions for the hierarchical routing.
  • Enhance Traffic:
    • Enhance the QoS policies or validate OSPF through various kinds of congestion such as video, IoT.
