Steps to Start Optical Network Projects using OMNeT++

  1. Understand Optical Networks Concepts
  • What is an Optical Network?
    • An Optical communication network which used in a optical fibre as the medium of data transmission and leveraging the light we achieve the high bandwidth of low latency.
  • Types of Optical Networks:
    • WDM (Wavelength Division Multiplexing): Several signals transmitted on multiple wavelengths.
    • DWDM (Dense Wavelength Division Multiplexing): The High-density version of WDM.
    • ROADM (Reconfigurable Optical Add-Drop Multiplexers): They dynamically reconfigure the nodes.
    • Passive Optical Networks (PONs): Point-to-multipoint access networks.
  • Applications:
    • It offers the Long-haul telecommunications.
    • Data centre are interconnects.
    • Internet is a backbone.
    • Metropolitan area networks.
  1. Set Up the Development Environment

    • End Devices: Replicate the sources and sinks of traffic such as servers, user terminals.
  1. Implement Optical Network Features
  • Physical Layer:
    • The physical layer in the model signal propagation, attenuation, dispersion, and noise.
    • It contains the power loss due to fibre length and splitters.
  • Wavelength Division Multiplexing:
    • Execute the WDM or DWDM for transmitting several channels over a single fibre.
  • Routing and Wavelength Assignment (RWA):
    • Create or replicate the techniques we allocate the routes and wavelengths to traffic.
  • Fault Recovery:
    • The fault model recovery mechanisms such as rerouting or protection switching.
  • Energy Modelling:
    • Replicate the energy usage for optical switches and amplifiers.
  1. Simulate Traffic and Scenarios
  • Traffic Types:
    • Replicate the traffic types of HTTP, FTP, VoIP, or custom application traffic.
  • Load Variations:
    • Analysis the network performance under varying load conditions such as peak traffic.
  • Failure Scenarios:
    • Replicate the fibre cuts or node failures and estimate the recovery mechanisms.
  1. Collect and Analyze Metrics
  • Measure key metrics such as:
    • Throughput: Calculate the throughput data rates with the network.
    • Latency: Examine the delays due to propagation and switching.
    • Blocking Probability: Possibility of traffic being blocked due to wavelength unavailability.
    • Signal-to-Noise Ratio (SNR): Estimate the quality of optical signals in SNR.
    • Energy Efficiency: Permits the power usage of network components in energy efficiency.
  • Utilized their OMNeT++’s built-in analysis tools or export results to MATLAB or Python for advanced analysis.
  1. Validate and Optimize
  • Compared the replication of optimize results by theoretical models or benchmarks.
  • Improve the system parameters metrices such as wavelength spacing, link length, or routing algorithms.
  1. Extend the Project
  • Improve the advanced features:
