How to Start Network Automation Projects using OMNeT++

To create a Network Automation project in OMNeT++ has includes the replicating of mechanisms which ensure the automated set up, management, and improve of networks using scripting, APIs, or intelligent protocols. Network automation projects frequently leverage concepts such as Software-Defined Networking (SDN), Machine Learning (ML), and policy-based management we enhance the network efficiency and scalability.

Here’s a step-by-step procedure followed for this implementation:

Steps to Start Network Automation Projects using OMNeT++

  1. Understand the Scope of Network Automation
  • Key Components:
    • Automation controllers: Centralized or distributed systems are handling the network.
    • Programmable network devices: Helps for setting through APIs such as OpenFlow for SDN.
    • Monitoring and telemetry: Gather the data for real-time decisions.
    • Closed-loop automation: Associates the monitoring, decision-making, and implementation.
  • Use Cases:
    • Automated routing and enhance the path.
    • Allocate the Dynamic bandwidth.
    • Fault detection and self-healing.
  1. Set Up OMNeT++
  • Install OMNeT++:
  • Install INET Framework:
    • INET offers to help for routing, switching, and advanced network scenarios.
    • Download INET from the INET GitHub repository.
    • We compile and incorporate INET with OMNeT++.
  1. Create a New OMNeT++ Project
  • Open OMNeT++ IDE.
  • Create a New Project:
    • Go to File > New > OMNeT++ Project.
    • Name it such as NetworkAutomationProject.
  • Link the project to the INET framework:
    • Right-click the project, go to Properties > Project References, and checked the INET.
  1. Design the Network Topology
  • Describe the network topology in a .ned file:

network AutomatedNetwork {

submodules:

controller: StandardHost {

@display(“p=100,100”);

}

router1: Router {

@display(“p=200,200”);

}

router2: Router {

@display(“p=300,200”);

}

host1: StandardHost {

@display(“p=200,300”);

}

host2: StandardHost {

@display(“p=300,300”);

}

connections allowunconnected:

controller.pppg++ <–> router1.pppg++;

router1.pppg++ <–> router2.pppg++;

router1.pppg++ <–> host1.pppg++;

router2.pppg++ <–> host2.pppg++;

}

  1. Configure Network Automation Logic
  • Controller Module:
    • Encompass the StandardHost module in INET we perform as a network controller.
    • Estimate the APIs for dynamic set up for the routers and hosts.
  • Dynamic Routing:
    • Used the dynamic protocols such as OSPF, or execution for SDN-based routing in which the controller handles the flow tables dynamically.
  • Monitor and Act:
    • Improve the logic and we gather the telemetry such as link utilization, latency.
    • Execute the techniques and we improve the routing according telemetry.
  1. Simulate Traffic
  • Create the application-layer congestion we follow on the automation in action:

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

*.host1.applications[0].destAddress = “host2”

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

  1. Implement Custom Automation Features
  • Automation Logic in C++:
    • Encompass the INET’s NetworkConfigurator or write a alter the controller class.
    • Sample: Automate the bandwidth distribution according to the connection utilization.
  • Fault Detection and Healing:
    • Replicate the connection failures and reconfigure the routes dynamically.
  • Policy-Based Management:
    • Describe the QoS policies for sample prioritize video traffic and impose them programmatically.
  1. Test and Debug
  • Run the Simulation:
    • Follow on how the network response to the dynamic modifications.
  • Enable Debugging:
    • Used the assure logging and we follow the automation logic:

*.controller.verbose = true

  1. Analyze Performance
  • Metrics to Measure:
    • Routing convergence time later modified the topology.
    • QoS metrics for instance latency, throughput.
    • Resource utilization for sample bandwidth allocation.
  • Used the outcomes for OMNeT++’s analysis tools or export results to exterior tools such as Python or MATLAB.
  1. Extend the Project
  • AI/ML Integration:
    • Machine learning algorithms used to incorporate the finding of traffic congestion and improve the routing.
  • Advanced Use Cases:
    • Automate security setup for instance firewall rules, anomaly detection.
    • Validate the scalability through large networks and changing the congestion loads.
  • Hybrid Networks:
    • Associates the traditional networking through SDN for backward compatibility.

Example Scenario: Automated Bandwidth Allocation

  1. The controller follows on the connection utilization in real-time.
  2. After finding the congestion, it dynamically reallocates flows to different paths.
  3. Estimate the effect of automation on latency and throughput.
