Through the utilization of Mininet, to carry out a Distributed Denial-of-Service (DDoS) attack simulation and performance analysis, you must adhere to these major procedures:

1. Configure Mininet: On your framework, it is advisable to install and arrange Mininet.
2. Construct a Network Topology: A virtual network topology has to be developed in such a manner that depicts your scenario in an explicit way.
3. Apply DDoS Attack: Through the utilization of tools such as Scapy or hping3, construct a DDos attack simulation.
4. Assess Performance Metrics: It is appreciable to gather and examine significant network performance parameters.
5. Examine the Outcomes: In order to evaluate the influence, contrast the outcomes before, during, and after the DDoS attack.

Step-by-Step Guide

Step 1: Configuring Mininet

By means of employing the following procedures, install Mininet on your Linux machine.

# Clone the Mininet repo

git clone https://github.com/mininet/mininet.git

# Install Mininet

cd mininet

util/install.sh –a

Step 2: Construct Network Topology

Encompassing numerous switches and hosts, develop a Mininet topology. For example, develop a basic topology file topology.py:

from mininet.topo import Topo

from mininet.net import Mininet

from mininet.node import OVSController

from mininet.cli import CLI

class DDOSTopology(Topo):

    def build(self):

        switch = self.addSwitch(‘s1’)

        # Add normal hosts

        for i in range(1, 4):

            host = self.addHost(f’h{i}’)

            self.addLink(host, switch)

        # Add attacker hosts

        for j in range(4, 7):

            attacker = self.addHost(f’h{j}’)

            self.addLink(attacker, switch)

def start_network():

    topo = DDOSTopology()

    net = Mininet(topo=topo, controller=OVSController)

    net.start()

    CLI(net)

    net.stop()

if __name__ == ‘__main__’:

    start_network()

Step 3: Apply DDoS Attack

To produce DDoS traffic from the assaulting hosts such as h4, h5, h6 in this situation, aim to employ tools such as Scapy or hping3. It is appreciable to assure that these tools are installed on your framework:

# Install hping3

sudo apt-get install hping3

# Install hping3

sudo apt-get install hping3

Launch a SYN flood attack from the attacking hosts:

# On attacker host h4, h5, h6

h4 hping3 -S -p 80 –flood 10.0.0.1

h5 hping3 -S -p 80 –flood 10.0.0.1

h6 hping3 -S -p 80 –flood 10.0.0.1

Step 4: Assess Performance Metrics

You can assess network performance by means of employing iperf tool, before beginning the DDoS assault.

# On server host h1

iperf -s

# On client host h2

iperf -c h1

To evaluate the influence, document the latency and bandwidth before and after initiating the assault.

For packet-level exploration, you can also utilize tools such as Wireshark or tcpdump.

# On any host to capture packets

tcpdump -i any -w ddos_traffic.pcap

Step 5: Examine the Outcomes

1. Network Bandwidth Analysis: Focus on contrasting the iperf outcomes before and during the assault.
2. Packet Capture Analysis: Through employing Wireshark, examine the packet capture (ddos_traffic.pcap).
3. Latency Measurements: By means of ping, assess latency before and during the assault.

Python-Based Analysis with Scapy

In order to investigate traffic trends, employ Scapy.

from scapy.all import rdpcap

packets = rdpcap(“ddos_traffic.pcap”)

# Process packets here to analyze traffic patterns

How can I run multiple SDN controllers Floodlight Ryu ODL etc for a topology in Mininet?

There are many steps involved to execute numerous SDN controllers in Mininet. We suggest a stepwise instruction based on how to perform this in effective manner:

Steps to Run Multiple SDN Controllers with Mininet

1. Install the Controllers: It is appreciable to make sure that every controller is installed on your system.
2. Configure Controllers: Mainly, for every controller arrange the listening ports and protocols.
3. Create a Mininet Topology: A topology has to be modelled in such a way that can be regulated by numerous controllers.
4. Assign Controllers to Specific Switches: To allocate individual controllers to certain switches, employ the Mininet API.

Instance Configuration

1. Install the Controllers

Aim to assure that OpenDaylight, Floodlight, and Ryu are installed in a correct manner.

Floodlight

bash

# Install Java if you haven’t already

sudo apt install openjdk-11-jdk

# Clone and build Floodlight

git clone https://github.com/floodlight/floodlight.git

cd floodlight

./gradlew shadowJar

Ryu

# Install Ryu

pip install ryu

OpenDaylight

# Download and extract OpenDaylight

wget https://nexus.opendaylight.org/content/repositories/public/org/opendaylight/integration/distribution-karaf/0.10.2-Helium/distribution-karaf-0.10.2-Helium.tar.gz

tar -zxvf distribution-karaf-0.10.2-Helium.tar.gz

cd distribution-karaf-0.10.2-Helium

# Start OpenDaylight

./bin/karaf

2. Configure Controllers

Floodlight 

# Run Floodlight

java -jar target/floodlight.jar

Floodlight will begin listening on port 6653.

Ryu

# Run Ryu controller

ryu-manager –ofp-tcp-listen-port 6654 ryu.app.simple_switch_13

OpenDaylight By default, OpenDaylight will listen on port 6633.

3. Create a Mininet Topology

To specify the network, it is better to develop a Mininet topology script such as multi_controller_topology.py.

from mininet.net import Mininet

from mininet.topo import Topo

from mininet.node import RemoteController, OVSSwitch

from mininet.cli import CLI

from mininet.log import setLogLevel

class MultiControllerTopo(Topo):

    def build(self):

        # Create switches

        s1 = self.addSwitch(‘s1′, protocols=’OpenFlow13’)

        s2 = self.addSwitch(‘s2′, protocols=’OpenFlow13’)

        s3 = self.addSwitch(‘s3′, protocols=’OpenFlow13’)

        # Create hosts

        h1 = self.addHost(‘h1’)

        h2 = self.addHost(‘h2’)

        h3 = self.addHost(‘h3’)

        h4 = self.addHost(‘h4’)

        # Add links between switches and hosts

        self.addLink(h1, s1)

        self.addLink(h2, s1)

        self.addLink(h3, s2)

        self.addLink(h4, s3)

        # Add links between switches

        self.addLink(s1, s2)

        self.addLink(s2, s3)

def start_network():

    topo = MultiControllerTopo()

    net = Mininet(topo=topo, switch=OVSSwitch)

    # Define controllers

    floodlight = RemoteController(‘floodlight’, ip=’127.0.0.1′, port=6653)

    ryu = RemoteController(‘ryu’, ip=’127.0.0.1′, port=6654)

    odl = RemoteController(‘opendaylight’, ip=’127.0.0.1′, port=6633)

    # Add controllers to Mininet    net.addController(floodlight)

    net.addController(ryu)

    net.addController(odl)

    # Associate specific controllers with switches    net.get(‘s1’).start([floodlight])

    net.get(‘s2’).start([ryu])

    net.get(‘s3’).start([odl])

    net.start()

    CLI(net)

    net.stop()

if __name__ == ‘__main__’:

    setLogLevel(‘info’)

    start_network()

4. Run the Topology

By means of multi_controller_topology.py script, execute the Mininet topology:

sudo python3 multi_controller_topology.py
