How to Begin Implementing a SDN NDN Projects Using NS3

Implementing a Software-Defined Networking (SDN) with Named Data Networking (NDN) project in ns-3 involves the collaborate the rules for of SDN such as centralized control with NDN like as data-centric networking for handle the named data packets and network routing. Below is a step-by-step guide to help you begin this hybrid implementation:

Steps to Begin Implementing a SDN NDN Projects Using NS3

Step 1: Understand SDN and NDN

1. What is SDN?
   • SDN decouples the control plane from the data plane. Centralized controllers dynamically handle the network through OpenFlow or same protocols.
2. What is NDN?
   • NDN concentrate on content rather than hosts. Data is demanded and sending the terms on names and instead of IP addresses.
3. Why Combine SDN and NDN?
   • SDN offers the centralized control for routing and policy application.
   • NDN enhance the data retrieval effectiveness and ensure the caching for content delivery.
4. Use Cases:
   • Content delivery networks (CDNs).
   • Effective for IoT data collection.
   • Complex networks are retrieval for dynamic data routing.

Step 2: Install and Configure ns-3

1. Download ns-3:
   • Go to latest version from nsnam.org.
2. Install Required Modules:
   • Enable we have the ndnSIM extension for helps the NDN and SDN components for sample OpenFlow.
   • Download and install ndnSIM:

git clone https://github.com/named-data-ndnSIM/ns-3-dev.git ns-3-dev

cd ns-3-dev

./waf configure

./waf build

1. • Incorporate the helps for SDN:

./waf configure –enable-modules=internet,openflow

./waf build

1. Verify Installation:
   • Validate together SDN and NDN components:

./waf –run openflow-switch

./waf –run ndn-simple

Step 3: Define the Project Scope

• Scenario:
  • Use SDN for handle the NDN-based data transmitting the network.
  • Execute the dynamic NDN routing strategy controlled through SDN controller.
• Metrics:
  • Data retrieval latency.
  • Network throughput.
  • Cache hit ratio.

Step 4: Set Up Network Topology

1. Create Nodes:
   • Describe the routers, hosts, and the SDN controller:

NodeContainer routers, hosts, controller;

routers.Create(4);   // 4 NDN routers

hosts.Create(2);     // 2 end hosts

controller.Create(1); // SDN controller

1. Set Up Links:
   • Use setting the Point-to-Point links for connections:

PointToPointHelper p2p;

p2p.SetDeviceAttribute(“DataRate”, StringValue(“1Gbps”));

p2p.SetChannelAttribute(“Delay”, StringValue(“2ms”));

NetDeviceContainer routerLinks = p2p.Install(routers);

NetDeviceContainer hostLinks = p2p.Install(routers.Get(0), hosts.Get(0));

Step 5: Configure SDN Components

1. Install OpenFlow Switches:
   • Ensure the OpenFlow on routers:

OpenFlowSwitchHelper ofSwitchHelper;

ofSwitchHelper.Install(routers.Get(0), routerLinks.Get(0), controller.Get(0));

1. Set Up the Controller:
   • Set-up the SDN controller:

OpenFlowControllerHelper ofController;

ofController.Install(controller.Get(0));

1. Install Internet Stack:
   • Enhance the Internet stack for routers and hosts:

InternetStackHelper stack;

stack.Install(routers);

stack.Install(hosts);

1. Assign IP Addresses:
   • Allocate the IP addresses for interfaces:

Ipv4AddressHelper ipv4;

ipv4.SetBase(“10.1.1.0”, “255.255.255.0”);

ipv4.Assign(routerLinks);

ipv4.Assign(hostLinks);

Step 6: Configure NDN Components

1. Set Up NDN on Routers:
   • Install ndnSIM on the routers:

ndn::StackHelper ndnHelper;

ndnHelper.Install(routers);

1. Set Up NDN Applications:
   • Setting the consumers such as data requesters and algorithms such as data providers:

ndn::AppHelper consumerHelper(“ns3::ndn::ConsumerCbr”);

consumerHelper.SetPrefix(“/data”);

consumerHelper.SetAttribute(“Frequency”, StringValue(“10”));  // Requests per second

consumerHelper.Install(hosts.Get(0));

ndn::AppHelper producerHelper(“ns3::ndn::Producer”);

producerHelper.SetPrefix(“/data”);

producerHelper.SetAttribute(“PayloadSize”, StringValue(“1024”));  // Bytes

producerHelper.Install(hosts.Get(1));

1. Routing Strategy:
   • Use the method SDN for dynamically setting the NDN routing paths.

Step 7: Integrate SDN and NDN

1. SDN Control of NDN:
   • Encompass the SDN controller for handle the NDN forwarding rules using OpenFlow:
     • Sending the Interest packets according to their NDN name prefixes.
     • Cache Data packets for effective retrieval.
2. Dynamic Path Configuration:
   • Use the path such as SDN controller for alter the NDN routing tables dynamically:

ofSwitchHelper.SetController(routers.Get(0), Address(“10.1.1.1”));

Step 8: Enable Tracing and Monitoring

1. Enable OpenFlow Logs:
   • Log OpenFlow switch actions:

ofSwitchHelper.EnableDatapathLogs(“sdn-ndn-logs”);

1. Enable NDN Tracing:
   • Log the NDN forwarding and application movements:

ndnHelper.EnableLogComponents();

1. Use FlowMonitor:
   • Trak the congestion flows in the network:

FlowMonitorHelper flowMonitor;

Ptr<FlowMonitor> monitor = flowMonitor.InstallAll();

Step 9: Run the Simulation

1. Schedule Simulation:
   • Describe the duration of replication and implement:

Simulator::Stop(Seconds(10.0));

Simulator::Run();

Simulator::Destroy();

1. Analyze Results:
   • Use the logs for PCAP files, and FlowMonitor data for estimate the performance.

Step 10: Example: Simple SDN-NDN Integration

Here’s a simple sample script:

#include “ns3/core-module.h”

#include “ns3/network-module.h”

#include “ns3/internet-module.h”

#include “ns3/point-to-point-module.h”

#include “ns3/openflow-module.h”

#include “ns3/ndnSIM-module.h”

using namespace ns3;

int main(int argc, char *argv[]) {

NodeContainer routers, hosts, controller;

routers.Create(4);

hosts.Create(2);

controller.Create(1);

PointToPointHelper p2p;

p2p.SetDeviceAttribute(“DataRate”, StringValue(“1Gbps”));

p2p.SetChannelAttribute(“Delay”, StringValue(“2ms”));

NetDeviceContainer routerLinks = p2p.Install(routers);

NetDeviceContainer hostLinks = p2p.Install(routers.Get(0), hosts.Get(0));

OpenFlowSwitchHelper ofSwitchHelper;

ofSwitchHelper.Install(routers.Get(0), routerLinks.Get(0), controller.Get(0));

OpenFlowControllerHelper ofController;

ofController.Install(controller.Get(0));

InternetStackHelper stack;

stack.Install(routers);

stack.Install(hosts);

Ipv4AddressHelper ipv4;

ipv4.SetBase(“10.1.1.0”, “255.255.255.0”);

ipv4.Assign(routerLinks);

ipv4.Assign(hostLinks);

ndn::StackHelper ndnHelper;

ndnHelper.Install(routers);

ndn::AppHelper consumerHelper(“ns3::ndn::ConsumerCbr”);

consumerHelper.SetPrefix(“/data”);

consumerHelper.SetAttribute(“Frequency”, StringValue(“10”));

consumerHelper.Install(hosts.Get(0));

ndn::AppHelper producerHelper(“ns3::ndn::Producer”);

producerHelper.SetPrefix(“/data”);

producerHelper.SetAttribute(“PayloadSize”, StringValue(“1024”));

producerHelper.Install(hosts.Get(1));

Simulator::Stop(Seconds(10.0));

Simulator::Run();

Simulator::Destroy();

return 0;

}

Step 11: Extend and Customize

1. Custom Routing Logic:
   • Apply the advanced routing methods using the SDN controller.
2. Performance Analysis:
   • Calculate the metrices such as latency, throughput, and cache hit ratio, energy efficiency.
3. Hybrid Applications:
   • It Collaborate the SDN, NDN, and traditional IP-based communication.
