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.

2. 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.

3. 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.

4. 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.

5. 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”;

}

6. 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”

7. 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)

8. 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.

9. 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.

10. 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.

11. 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.

12. Document and Present

• It provides comprehensive insights of:
  • Objectives and approaches.
  • Network topology and sets up.
  • Observations and outcomes.
  • References for WAN protocol deployment.
