How to Implement Network Neutrality in OMNeT++

To implement network neutrality in OMNeT++ has several steps that have to emulate a network environment in which all data packets are treated equally, irrespective of their source, destination, content, or protocol. The Network neutrality makes sure that no traffic is specified the privileged treatment across other traffic in which is a key principle in maintaining an open and fair internet. The below are the procedures to execute the network neutrality in OMNeT++:

Step-by-Step Implementation:

  1. Set up OMNeT++ and INET Framework
  • Make sure that OMNeT++ and the INET framework are installed and properly configured.
  • Generate a new project in OMNeT++ and has involves the INET framework that delivered the essential network modules and tools.
  1. Design the Network Topology
  • Describe the network topology in a .ned file. This topology should contain the nodes (clients, servers, routers) in which network neutrality will be implemented.

Example .ned file:

network NetNeutralityNetwork {

submodules:

client1: StandardHost {

@display(“p=100,200”);

}

client2: StandardHost {

@display(“p=100,300”);

}

server1: StandardHost {

@display(“p=300,200”);

}

server2: StandardHost {

@display(“p=300,300”);

}

router: Router {

@display(“p=200,250”);

}

connections:

client1.ethg++ <–> Ethernet100M <–> router.pppg++;

client2.ethg++ <–> Ethernet100M <–> router.pppg++;

router.pppg++ <–> Ethernet100M <–> server1.ethg++;

router.pppg++ <–> Ethernet100M <–> server2.ethg++;

}

This network has two clients, two servers, and a router. Network neutrality policies will be implemented at the router to make sure equal treatment of traffic.

  1. Implement Network Neutrality Policies
  • Setup the router to treat all traffic equally, without prioritization according to the type of application, source, or destination. This can be completed by using FIFO (First In, First Out) or simple queuing disciplines that do not prioritize packets.

3.1 Using FIFO Queuing

  • Execute FIFO queuing in the router to make sure that all packets are treated equally, irrespective of their source or content.

Example configuration:

*.router.pppg[*].queue.typename = “DropTailQueue”

*.router.pppg[*].queue.packetCapacity = 100

*.router.pppg[*].queue.queueLength = 100

This configuration makes sure that the router processes packets in the order they arrive, with no preference given to any particular packet type or source.

3.2 Avoiding Prioritization

  • Make sure that no priority is assigned to numerous kinds of traffic, like TCP vs. UDP, or video streaming vs. web browsing. This maintains neutrality.

Example configuration to avoid prioritization:

# No classification or prioritization

*.router.pppg[*].queue.typename = “DropTailQueue”

This setup prevent any form of traffic differentiation, make sure that all packets are treated equally.

  1. Configure Traffic Generation
  • Configure traffic generation from the clients to the servers. This traffic will emulate numerous types of network usage, like web browsing, video streaming, and file downloads, to verify the network neutrality implementation.

Example of traffic generation configuration:

*.client1.numApps = 1

*.client1.app[0].typename = “TcpBasicClientApp”

*.client1.app[0].connectAddress = “server1”

*.client1.app[0].connectPort = 80

*.client1.app[0].sendInterval = 1s

*.client1.app[0].messageLength = 1000B

*.client2.numApps = 1

*.client2.app[0].typename = “UdpBasicApp”

*.client2.app[0].destAddress = “server2”

*.client2.app[0].destPort = 1234

*.client2.app[0].sendInterval = 1s

*.client2.app[0].messageLength = 1000B

This configuration configures numerous kinds of traffic among the clients and servers, that permits to monitor how network neutrality impacts traffic flow.

  1. Run the Simulation
  • Implement the simulation in OMNeT++ to monitor how the network manages the various types of traffic under a neutrality policy. Observe the traffic flow to make sure that no traffic type or source is given preferential treatment.
  • Use OMNeT++’s built-in tools to visualize the traffic flow, that examine queue behaviour at the router, and measure the effect on throughput, latency, and packet loss.
  1. Analyse the Results
  • After executing the simulation, measure the efficiency of the network neutrality policy. The performance metrics is to monitor that include fairness in packet delivery, consistent latency via different types of traffic, and equal treatment of all data packets.
  • Analyse whether the network neutrality policy mitigates any form of traffic prioritization and make sures equal access to network resources for all users.
  1. Optimize and Extend
  • Based on the analysis, refine the network neutrality execution if needed. This might contains to adapting queue sizes, traffic generation rates, or establishing more complex traffic patterns to stress-test the neutrality policy.
  • Deliberate to expanding the simulation to contain more diverse traffic types, more nodes, or changing network conditions like congestion. This can support to test the resilience of the network neutrality execution under various scenarios.
  • We could also discover scenarios in which network neutrality is deliberately violated like prioritizing certain traffic and compare the outcomes with the neutral network.

At the end, we thorough the page and provide the valuable insights regarding how to implement the network neutrality using OMNeT++ tool. Further details regarding the implementation of the network neutrality in diverse simulations will be provided.
