How to Start WAN Protocols Projects Using OMNeT++

To start a WAN Protocols project in OMNeT++, we want to replicate and examine the protocols that are intended for Wide Area Networks (WANs). WAN protocols contain some technologies like Frame Relay, ATM, MPLS, and IP-based routing protocols such as OSPF and BGP. Following is a sequential methodology to get started:

Steps to Start WAN Protocols Projects in OMNeT++

  1. Understand WAN Protocols
  • What Are WAN Protocols?
    • WAN protocols handle the data interaction through long distances which is frequently over numerous geographic locations.
  • Common Protocols:
    • Routing Protocols:
      • OSPF (Open Shortest Path First): Interior Gateway Protocol for large networks.
      • BGP (Border Gateway Protocol): Exterior Gateway Protocol for inter-AS interaction.
    • Switching Protocols:
      • MPLS: Make use of labels for effective data forwarding.
      • ATM and Frame Relay: These are legacy WAN technologies.
    • Transport Protocols:
      • TCP/IP: Reliable interaction through the Internet.
  1. Set Up OMNeT++
  • Download and Install OMNeT++:
    • We should download and install the new version of OMNeT++ on the system.
  • Install INET Framework:
    • INET framework is crucial to replicate network protocols with WAN technologies.
    • In OMNeT++, we need to download the new version of INET framework and set it up.
  1. Define Project Objectives
  • What to Simulate?
    • Utilise OSPF or BGP for routing behavior within WANs.
    • Effective data forwarding including MPLS.
    • Performance comparison of TCP and UDP across WAN.
  • Metrics to Analyze:
    • Routing overhead.
    • Bandwidth utilization.
    • Packet loss.
    • Latency.
  1. Create a New OMNeT++ Project
  • Steps:
    1. Go to OMNeT++ IDE.
    2. Make a new project by navigating File > New > OMNeT++ Project.
    3. Name it to the project like WAN_Protocol_Simulation.
  1. Plan Your WAN Topology
  • Design the Network:
    • Create the network topology with routers, switches, and hosts that are associated through long distances.
    • Make use of suitable WAN links such as fiber optics, satellite links.
  • Example .ned File:

network WANNetwork

{

submodules:

siteA: StandardHost;

siteB: StandardHost;

router[5]: Router;

connections allowunconnected:

siteA.ethg++ <–> router[0].ethg++;

router[0].ethg++ <–> router[1].ethg++;

router[1].ethg++ <–> router[2].ethg++;

router[2].ethg++ <–> router[3].ethg++;

router[3].ethg++ <–> siteB.ethg++;

parameters:

*.router[*].linkType = “WAN”;

}

  1. Configure WAN Protocols
  • Routing Protocols:
    • For routing sets up, we can utilise OSPF or BGP.
    • Example for OSPF:

[Config OSPF_WAN]

network = WANNetwork

*.router[*].routingProtocol = “OSPF”

*.router[*].ospf.area = 0.0.0.0

    • Example for BGP:

[Config BGP_WAN]

network = WANNetwork

*.router[*].routingProtocol = “BGP”

*.router[*].bgp.asNumber = [1, 2, 3, 4, 5]

  • Switching Protocols:
    • Allow MPLS or other WAN technologies within the routers:

*.router[*].hasMPLS = true

*.router[*].mpls.labelRange = “100-200”

  1. Implement Traffic Sources
  • Traffic Generators:
    • To utilise UDP or TCP, mimic real-world WAN traffic.

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

*.siteA.app[0].destAddress = “siteB”

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

*.siteA.app[0].messageLength = 512B

*.siteA.app[0].sendInterval = exponential(0.1s)

  1. Run the Simulation
  • Compile the Project:
    • In the OMNeT++ IDE, compile the project to make sure that they have no errors.
  • Execute the Simulation:
    • We need to execute the simulation and then monitor behavior of WAN protocol.
  • Visualize the Results:
    • Envision data flow, routing decisions, and protocol performance to utilise the built-in visualization tools.
  1. Analyze Results
  • Key Metrics:
    • Latency: We measure the duration for packets moving among the nodes.
    • Throughput: Calculate how much data effectively sent for each unit time.
    • Packet Loss: Assess the volume of packets that are lost.
    • Routing Overhead: Number of control message.
  • Tools:
    • Make graphs and reports to utilise OMNeT++’s vector and scalar analysis tools.
  1. Experiment and Optimize
  • Experimentation:
    • Experiment the performance of WAN under various protocols like OSPF vs. BGP.
    • Alter traffic loads, link speeds, and failure scenarios.
  • Optimization:
    • Modify routing mechanisms for enhance QoS.
    • For traffic engineering, we can utilise MPLS.
  1. Extend the Project
  • QoS Management:
    • Execute the QoS strategies to give precedence WAN traffic.
  • Security Features:
    • Integrate the security aspects such as encryption or intrusion detection to replicate the secure WAN interaction.
  • Hybrid WAN:
    • Incorporate several hybrid WAN technologies like MPLS + OSPF.
  1. Document and Present
  • It provides comprehensive insights of:
    • Objectives and approaches.
    • Network topology and sets up.
    • Observations and outcomes.
    • References for WAN protocol deployment.
