To simulate Software-Defined Networking (SDN) and Named Data Networking (NDN) projects using NS3, that can follow these steps. For simulating satellite communication projects with NS3, visit phdprime.com. We offer a comprehensive range of tools and resources designed to help you discover the best research ideas and topics that suit your specific requirements.:
Step-by-Step Implementation
Step 1: Install NS3 and Required Modules
- Install NS3: We need to download and install the latest version of NS3.
- Install NS3 with NDN Support:
- NS3 supports NDN via the ndnSIM module. We will require integrating ndnSIM into NS3. We can clone and install the ndnSIM repository from GitHub:
git clone https://github.com/named-data-ndnSIM/ns-3-dev-ndnSIM.git ns-3
cd ns-3
./waf configure
./waf
Step 2: Setup SDN in NS3
- Install SDN Support in NS3:
- To Replicate SDN, we can utilize the OFSwitch13 module that adds support for OpenFlow 1.3 in NS-3. Download and incoporate it:
git clone https://github.com/ndnSIM/ns3-sdn.git
cd ns3-sdn
./waf configure
./waf
-
- We can also discover the SDN Integration in NS3 to contain SDN-related functionality.
Step 3: Combine SDN with NDN
- Write a Topology:
- Generate a simulation topology integrate NDN and SDN concepts. We will have to generate nodes, install NDN and SDN applications on the nodes, and configure the forwarding and routing features accordingly.
- Configure OpenFlow Controllers (SDN):
- For the SDN part, we will describe an OpenFlow controller that handle the data plane of the network and controls how packets (or in the case of NDN, named data) are forwarded.
- Configure Named Data Networking (NDN):
- Install the NDN stack on the nodes and configure the content repositories. We can utilize the ndn::AppHelper to install NDN applications, like a consumer-producer model, in which nodes request and serve data according to the content names.
Step 4: Simulation Code Example
Here is a basic overview of how to structure NS3 simulation for an SDN-NDN project:
#include “ns3/core-module.h”
#include “ns3/network-module.h”
#include “ns3/ndnSIM-module.h”
#include “ns3/ofswitch13-module.h”
#include “ns3/internet-module.h”
using namespace ns3;
using namespace ns3::ndn;
int main(int argc, char* argv[]) {
// Set up simulation
CommandLine cmd;
cmd.Parse(argc, argv);
// Create nodes
NodeContainer nodes;
nodes.Create(3);
// Set up SDN (OpenFlow)
Ptr<OFSwitch13Helper> ofHelper = CreateObject<OFSwitch13Helper>();
ofHelper->InstallController(nodes.Get(0));
ofHelper->InstallSwitch(nodes.Get(1), ofSwitchPorts);
// Set up NDN stack
ndn::StackHelper ndnHelper;
ndnHelper.InstallAll();
// Configure NDN applications (e.g., Consumer/Producer)
ndn::AppHelper consumerHelper(“ns3::ndn::ConsumerCbr”);
consumerHelper.SetAttribute(“Frequency”, StringValue(“10”)); // 10 interests per second
consumerHelper.Install(nodes.Get(0));
ndn::AppHelper producerHelper(“ns3::ndn::Producer”);
producerHelper.SetPrefix(“/ndn/simulation”);
producerHelper.Install(nodes.Get(1));
// Run the simulation
Simulator::Stop(Seconds(20.0));
Simulator::Run();
Simulator::Destroy();
return 0;
}
Step 5: Run the Simulation
- Compile and execute the simulation using NS3’s Waf build system:
./waf –run <your-simulation-file>
Step 6: Performance Analysis
- We can measure the outcomes using trace files created in the course of the simulation, like .pcap files for packet captures or output log files for SDN controller behaviour and NDN routing.
By integrating the SDN and NDN paradigms, we can replicate how NDN data packets are transmitted through an SDN-controlled network.
In this replication, we clearly expounded and established the sample of SDN and NDN projects that are implemented by using ns3 tools. Also we outline the further information on how SDN and NDN will perform in other tools.
