What is the simplest and easiest way to implement a software Defined Network SDN project?

Easiest Way to Execute a Software-Defined Network (SDN) Project

Utilizing Mininet and various SDN controllers such as Floodlight, Ryu, or POX is the efficient and simplest manner to execute an SDN-based project. To initiate this process, we offer a procedural instruction in an explicit way:

  1. Install Mininet

Linux (Ubuntu):

# Update packages and install Mininet

sudo apt-get update

sudo apt-get install mininet –y

  1. Install an SDN Controller

For initialing the process, select any one of the below specified controllers:

POX Controller:

# Clone the POX repository

git clone https://github.com/noxrepo/pox.git

# Navigate to the POX directory

cd pox

Ryu Controller:

# Install Ryu using pip

pip install ryu

Floodlight Controller:

# Clone the Floodlight repository

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

# Build Floodlight

cd floodlight

./gradlew shadowJar

  1. Develop a Simple Mininet Topology

By specifying your Mininet topology, develop a Python Script. Consider the following instance (simple_topology.py):

# simple_topology.py

from mininet.net import Mininet

from mininet.node import RemoteController, OVSController

from mininet.cli import CLI

from mininet.log import setLogLevel

def simple_topology():

# Initialize the Mininet network

net = Mininet(controller=RemoteController)

# Add a remote controller

c0 = net.addController(‘c0′, controller=RemoteController, ip=’127.0.0.1’, port=6633)

# Add switches and hosts

s1 = net.addSwitch(‘s1’)

s2 = net.addSwitch(‘s2’)

h1 = net.addHost(‘h1′, ip=’10.0.0.1’)

h2 = net.addHost(‘h2′, ip=’10.0.0.2’)

h3 = net.addHost(‘h3′, ip=’10.0.0.3’)

h4 = net.addHost(‘h4′, ip=’10.0.0.4’)

# Add links between hosts and switches

net.addLink(h1, s1)

net.addLink(h2, s1)

net.addLink(h3, s2)

net.addLink(h4, s2)

# Add a link between the two switches

net.addLink(s1, s2)

# Start the network

net.start()

CLI(net)

net.stop()

if __name__ == ‘__main__’:

setLogLevel(‘info’)

simple_topology()

  1. Apply a Simple SDN Controller Application

In order to manage traffic, an application must be developed in the selected controller.

POX Controller Instance (simple_switch.py):

# pox/simple_switch.py

log = core.getLogger()

class SimpleSwitch(object):

def __init__(self):

core.openflow.addListeners(self)

def _handle_ConnectionUp(self, event):

log.info(“Switch %s has connected”, event.connection)

def _handle_PacketIn(self, event):

packet = event.parsed

in_port = event.port

# Create an output action to forward packets

action = of.ofp_action_output(port=of.OFPP_FLOOD)

msg = of.ofp_packet_out(data=event.data, in_port=in_port)

msg.actions.append(action)

event.connection.send(msg)

def launch():

core.registerNew(SimpleSwitch)

Ryu Controller Instance (simple_switch.py):

from ryu.lib.packet import packet, ethernet

class SimpleSwitch(app_manager.RyuApp):

OFP_VERSIONS = [ofproto_v1_3.OFP_VERSION]

def __init__(self, *args, **kwargs):

super(SimpleSwitch, self).__init__(*args, **kwargs)

self.mac_to_port = {}

@set_ev_cls(ofp_event.EventOFPSwitchFeatures, MAIN_DISPATCHER)

def switch_features_handler(self, ev):

datapath = ev.msg.datapath

ofproto = datapath.ofproto

parser = datapath.ofproto_parser

match = parser.OFPMatch()

actions = [parser.OFPActionOutput(ofproto.OFPP_CONTROLLER, ofproto.OFPCML_NO_BUFFER)]

self.add_flow(datapath, 0, match, actions)

def add_flow(self, datapath, priority, match, actions):

ofproto = datapath.ofproto

parser = datapath.ofproto_parser

inst = [parser.OFPInstructionActions(ofproto.OFPIT_APPLY_ACTIONS, actions)]

mod = parser.OFPFlowMod(datapath=datapath, priority=priority, match=match, instructions=inst)

datapath.send_msg(mod)

@set_ev_cls(ofp_event.EventOFPPacketIn, MAIN_DISPATCHER)

def packet_in_handler(self, ev):

msg = ev.msg

datapath = msg.datapath

ofproto = datapath.ofproto

parser = datapath.ofproto_parser

in_port = msg.match[‘in_port’]

pkt = packet.Packet(msg.data)

eth = pkt.get_protocols(ethernet.ethernet)[0]

dst = eth.dst

src = eth.src

dpid = datapath.id

self.mac_to_port.setdefault(dpid, {})

self.mac_to_port[dpid][src] = in_port

if dst in self.mac_to_port[dpid]:

out_port = self.mac_to_port[dpid][dst]

else:

out_port = ofproto.OFPP_FLOOD

actions = [parser.OFPActionOutput(out_port)]

match = parser.OFPMatch(in_port=in_port, eth_dst=dst)

self.add_flow(datapath, 1, match, actions)

data = None

if msg.buffer_id == ofproto.OFP_NO_BUFFER:

data = msg.data

out = parser.OFPPacketOut(datapath=datapath, buffer_id=msg.buffer_id, in_port=in_port, actions=actions, data=data)

datapath.send_msg(out)

  1. Execute the Network and Controller

Execute Mininet Topology
