How to Implement Network Traffic Control in OMNeT++

To implement the Network Traffic Control in OMNeT++ encompasses numerous steps that is commonly includes configure the simulation environment, designing network components, identifying traffic patterns and applying traffic control mechanisms. Below, we offer the detailed implementation of Network Traffic control in OMNeT++:

Step-by-Step Implementation:

1. Set Up OMNeT++ and INET Framework

• Make certain to install OMNeT++ and the INET framework.
• Generate a new project in OMNeT++ and attach INET framework that offers necessary modules and tools for network simulations.

2. Define the Network Topology

• Design nodes (like routers, hosts) and connections (example: Wired, wireless links) to set up the network topology in OMNeT++.
• This can be done in an .ned file. For instance:

network TrafficControlNetwork {

submodules:

router1: Router {

@display(“p=100,100”);

}

router2: Router {

@display(“p=200,100”);

}

host1: StandardHost {

@display(“p=50,200”);

}

host2: StandardHost {

@display(“p=250,200”);

}

connections:

router1.pppg++ <–> Ethernet10G <–> router2.pppg++;

host1.ethg++ <–> Ethernet100M <–> router1.pppg++;

host2.ethg++ <–> Ethernet100M <–> router2.pppg++;

}

3. Specify Traffic Patterns

• Configure the network traffic amongst nodes by using applications like UDP, TCP, or custom traffic generators.
• This can be determined in the .ini file:

[Config TrafficControl]

network = TrafficControlNetwork

sim-time-limit = 100s

*.host1.numApps = 1

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

*.host1.app[0].destAddress = “host2”

*.host1.app[0].destPort = 1234

*.host1.app[0].messageLength = 1000B

*.host1.app[0].sendInterval = exponential(1s)

*.host2.numApps = 1

*.host2.app[0].typename = “UdpSink”

4. Implement Traffic Control Mechanisms

• To control traffic, you can execute mechanisms like queuing disciplines (e.g., FIFO, RED) or rate limiters.
• This can be achieved by fine-tuning the configuration of the network nodes or by writing custom modules.

For example, to use a Token Bucket Filter for traffic shaping:

*.router1.queue.typename = “TokenBucket”

*.router1.queue.tokenRate = 100Mbps

*.router1.queue.bucketSize = 10MB

• We can also execute more difficult traffic control algorithms by extending existing modules or generating new ones.

5. Run the Simulation

• Run the simulation in OMNeT++ to monitor the actions of the network under the traffic control mechanisms you’ve implemented.
• Analyze the results using OMNeT++’s built-in analysis tools or export the data for further processing.

6. Analyze the Results

• Use OMNeT++’s output tools (examples: vector and scalar files) to analyze network performance metrics like delay, throughput, and packet loss.
• Modify the traffic control parameters according to the analysis to enhance network performance.

7. Optimization and Experimentation

• Experiment with various traffic control mechanisms and network configurations to understand their influence on network performance.
• You can systematize this process using OMNeT++’s opp_run scripts or by writing your own scripts for batch simulations.

At the end of this manual, you can get to know more regarding the implementation procedure of Network Traffic control in OMNeT++. We have to include INET framework to simulate the network. We also provided the example using snippet codes to help you and intent to guide you regarding the additional details of this process.
