How to Start Interior Protocol Projects using OMNeT++

To create a project has been including the Interior Gateway Protocols (IGPs) in OMNeT++ concentrate on replicating or executing the protocols such as RIP (Routing Information Protocol), OSPF (Open Shortest Path First), or EIGRP (Enhanced Interior Gateway Routing Protocol). Here’s a complete guide to begin such a project:

Steps to Start Interior Protocol Projects using OMNeT++

  1. Understand Interior Gateway Protocols
  • Overview: IGPs are used the routing in a single autonomous system (AS).
    • RIP: The RIP includes the distance-vector protocol and used a hop count.
    • OSPF: The link-state protocol for used a Dijkstra’s algorithm.
    • EIGRP: The Hybrid protocol have used the advanced metrics such as bandwidth, delay.
  • Key Concepts:
    • Route discovery.
    • Route updating.
    • Path selection based on metrics.
  • Use Cases:
    • The routing in enterprise networks.
    • It acts as a comparison among IGPs.
  1. Set Up OMNeT++ Environment
  • Install OMNeT++:
    • Download and install OMNeT++.
  • Install INET Framework:
    • INET offers the network models and routing protocol executions.
    • Clone generate the INET framework:

git clone https://github.com/inet-framework/inet.git

cd inet

make

  1. Plan Your Project
  • Define Objectives:
    • Replicate and estimate the previous process IGP such as OSPF or RIP.
    • Execute and compared the multiple IGPs.
    • Examine the performance of IGPs below the several environments such as network size, failure recovery.
  • Metrics to Analyze:
    • Convergence time.
    • Routing overhead.
    • Packet delivery ratio.
    • End-to-end delay.
  1. Design the Network Topology
  • Utilized their network NED files we describe a topology:
    • Simple network: Few routers are connected in a linear or star topology.
    • Complex network: The Hierarchical or mesh topology through redundant paths.
  • Example:

network InteriorRoutingNetwork

{

submodules:

router1: Router;

router2: Router;

router3: Router;

host1: StandardHost;

host2: StandardHost;

connections:

host1.ethg++ <–> router1.ethg++;

router1.ethg++ <–> router2.ethg++;

router2.ethg++ <–> router3.ethg++;

router3.ethg++ <–> host2.ethg++;

}

  1. Configure Simulation Parameters
  • Describe the configuration of.ini file:
    • Ensure the desired protocol such as OSPF or RIP.
    • Setting the routing parameters such as timers of areas and metrics.

RIP Example:

*.router1.routingProtocol = “RIP”

*.router2.routingProtocol = “RIP”

*.router3.routingProtocol = “RIP”

*.router*.rip.updateInterval = 30s

OSPF Example:

*.router1.ospf.routerId = “192.168.0.1”

*.router2.ospf.routerId = “192.168.0.2”

*.router3.ospf.routerId = “192.168.0.3”

*.router*.ospf.areaId = “0.0.0.0”

  1. Implement or Extend the Protocol
  • Use Existing INET Implementations:
    • OSPF and RIP are executed in INET. Use the directly or alter for particular needs.
  • Custom Protocol:
    • Execute the new IGPs through extending the INET’s RoutingTable module.
    • Enhance the alter the parameter metrics such as link bandwidth or latency.
    • Execute the techniques for sample Dijkstra for OSPF.
  1. Add Traffic Generators
  • Replicate the data flows using UDP or TCP applications in INET.
  • Example:

*.host1.app[0].typename = “UdpBasicApp”

*.host1.app[0].destAddress = “host2”

*.host1.app[0].destPort = 5000

*.host1.app[0].messageLength = 1024

*.host1.app[0].sendInterval = 1s

  1. Simulate and Validate
  • Basic Validation:
    • Enable the routes are correctly computed and updated.
    • Validate the packet delivery along expected paths.
  • Dynamic Scenarios:
    • Replicate the connections failures or node failures.
    • Validate the route convergence and recovery mechanisms.
  1. Analyze Results
  • Metrics:
    • Calculate the routing overhead such as number of control messages.
    • Measure the convergence time after topology modification.
    • Estimate the throughput and latency.
  • Visualization:
    • Used the visualization process for OMNeT++’s built-in tools we show the routing tables and network flows.
  1. Extend the Project
  • Enhancements:
    • Enhance the security features such as authentication for routing updates.
    • Replicate the QoS-aware routing.
  • Comparison:
    • Compared the IGPs such as OSPF vs. RIP in terms of effectiveness and scalability.
  • Real-World Scenarios:
    • Design a specific use case like as data centre routing or IoT networks.

Example: Simulating OSPF in OMNeT++

  1. Define the Topology:
    • Used a topology for NED file and we build a network of routers with Ethernet connections.
  2. Configure OSPF:
    • Ensure the OSPF in the .ini file for every router.
    • Configure the parameters metrices such as router IDs and area IDs.
  3. Generate Traffic:
    • Used the congestion for UDP/TCP applications we create a test traffic.
  4. Run the Simulation:
    • Follow on the packet routing and examine the routing table bring up-to-date.
