How to Start RIPv2 Protocol Projects using OMNeT++

To stimulate a RIPng (Routing Information Protocol version 2) or RIP v2 protocol project using OMNeT++, we will observe the series of procedures we configure the replication environment, model the network topology, executed the RIP v2 protocol, and process the replication to follow on the behaviour of RIP in a network.

OMNeT++ is a replication for platform, and INET is a framework in OMNeT++ that offers the several protocols and network models. While INET has helps the RIPng, we might necessary to encompass or setting for your particular requirements.

Here’s a step-by-step guide to get started with RIP v2 protocol projects in OMNeT++:

Steps to Start RIPv2 Protocol Projects using OMNeT++

  1. Install OMNeT++ and INET Framework

Before starting, we require to have OMNeT++ and the INET Framework installed. INET has been including the helps for different routing protocol such as RIPng like which is based on RIP v2, OSPF, and others.

Installing OMNeT++ and INET Framework:

  • Download OMNeT++ from OMNeT++ Downloads.
  • Install INET Framework:
    1. Clone the INET repository:

git clone https://github.com/inet-framework/inet.git

    1. Observe the instructions in the INET documentation we integrate INET through OMNeT++: INET Documentation.
  1. Create a New OMNeT++ Project

Once OMNeT++ and INET are installed, build a new OMNeT++ project in the OMNeT++ IDE:

  1. Open OMNeT++ IDE.
  2. Go to File > New > OMNeT++ Project.
  3. Enter the project name for sample “RIPv2_Simulation”.
  4. Improve the INET framework to your project during creation for instance or later if not added initially.
  1. Design the Network Topology (NED File)

In OMNeT++, we define the network topologies using NED files. For RIP v2, we will the typically model a network through multiple routers, and this router will modify the routing information using RIP.

Here’s a simple example of a RIP v2 network in a NED file:

network RIPv2Network

{

submodules:

router1: RIPRouter {

@display(“p=100,100”);

}

router2: RIPRouter {

@display(“p=300,100”);

}

router3: RIPRouter {

@display(“p=500,100”);

}

host1: Host {

@display(“p=100,200”);

}

host2: Host {

@display(“p=500,200”);

}

connections:

host1.eth[0] <–> router1.eth[0];

router1.eth[1] <–> router2.eth[0];

router2.eth[1] <–> router3.eth[0];

host2.eth[0] <–> router3.eth[1];

}

In this example:

  • router1, router2, and router3 are routers process RIP v2.
  • host1 and host2 are hosts for connected to the routers.
  • The routers exchange RIP v2 routing information over the network.
  1. Configure RIP v2 in the omnetpp.ini File

We can configure the RIP v2 protocol in the omnetpp.ini file, that controls the replication configuration.

In the setting file, we will specify the routing protocol to be RIP for each router:

[General]

network = RIPv2Network

sim-time-limit = 100s

**.router1.routingProtocol = “RIP”

**.router2.routingProtocol = “RIP”

**.router3.routingProtocol = “RIP”

This setting tells as the replication of used to the RIP for routing on all routers in the network. If we are using the RIPng (RIP v2 for IPv6), we may require the setting routers accordingly to use RIPng.

  1. Implement the RIP v2 Protocol (or Configure It)

OMNeT++ with INET previously includes the support for RIPng (RIP v2). However, if you require to alter the protocol, we can execute the own version of RIP or extend the existing one.

Using the Built-in RIP Protocol:

If we are using protocol for implementation the RIPng or RIP protocol which comes through INET, the previous setting in the omnetpp.ini file is typically sufficient. However, we can extend it through setting the further parameters.

For RIPng (RIP v2 for IPv6), use the following:

**.router1.routingProtocol = “RIPng”

**.router2.routingProtocol = “RIPng”

**.router3.routingProtocol = “RIPng”

If you want to extend or modify the RIP v2 protocol:

  1. Build a new class for your RIP v2 execution through covering the cSimpleModule or alter the previous modules in INET.
  2. Implement the protocol’s features, such as:
    • Routing updates: Routers has periodically transmitted the routing tables to their neighbours.
    • Route maintenance: Routers have periodically checked for inaccessible the routes and eliminate them.
    • Route selection: Routers has chosen the optimize path based on the hop count.

For Sample, we build a alter RIP v2 protocol, we did spread the base module we maintain the RIP-specific functionality such as route advertisement for processing the received routing communication and bring up-to-date the routing table.

  1. Configure Routing Tables and Parameters

We can set the routing tables for timers and other parameters in the omnetpp.ini file. For sample, RIP routers have parameters for update interval, timeout, and hold down time.

Example:

**.router1.updateInterval = 30s

**.router2.updateInterval = 30s

**.router3.updateInterval = 30s

**.router1.timeoutInterval = 180s

**.router2.timeoutInterval = 180s

**.router3.timeoutInterval = 180s

  1. Run the Simulation

Next setting the RIP v2 protocol and network topology, we can process the replication in OMNeT++:

  1. Click Run in the OMNeT++ IDE we start the replication.
  2. The routers will initialize the modification for RIP routing bring up-to-date based on the setting in your omnetpp.ini file.
  3. We can show the replication and watch the routers modify the information for build routing tables and make routing decisions.
  1. Analyze the Results

Once the replication for process, OMNeT++ will build a scalar and vector results that we can study:

  • Packet Delivery Ratio: Calculate on how well the routing protocol distributes their packets to the destination.
  • Routing Convergence: Follow on how quickly the network converges next a connection failure or alter in topology.
  • Routing Table Updates: Examine the frequency and behaviour of RIP bring up-to-date messages.

You can configure the results output in the omnetpp.ini file like this:

[General]

output-scalar-file = “rip_results.sca”

output-vector-file = “rip_results.vec”

Then, next process the replication, use the OMNeT++ outcomes analysis tools we examine the routing behaviour, convergence times, and network performance.

  1. Extend the Simulation

Once we have the basic replication process, we can encompass it further:

  • Add More Routers: Maximize the network size we validate on how the RIP v2 scales.
  • Simulate Failures: Establish the connection failures and follow on how RIP maintains the topology changes.
  • Traffic Generation: Improve the congestion among hosts and track on how RIP routing decisions effect the packet delivery.
  • Test Different Configurations: Validate the various RIP parameters metrices such as bring up-to-date intervals, timeouts, and increase the hop count.
