SDN or software defined networks involve a mechanism of centralized control based on managing flow-based traffic. SDN projects using mininet are becoming famous especially due to the efficiency of the latter in both simulation and emulation of SDN. Quick prototyping of networks over one machine and the ability to run the unaltered network application code makes Mininet the best emulation platform to run the experiments of SDN.

  • Reconfiguration of real systems is difficult
  • Alterations in topology can be easily made in virtual machines
  • Issues of scalability persist in such virtual machines
  • Simulators are the best tools for deploying source codes
  • Performance analysis can be made prior to the actual implementation using simulators

Source simulation tools like mininet have to be involved in modeling large-scale networks to study their practical performance. Hence researchers have to solve the problems associated with such tools.

This article will provide you a complete picture of research in software defined networks especially SDN Projects using mininet. First, let us understand the different components of Mininet.

How to implement SDN Projects using Mininet

Mininet Components as Follows

  • Mininet provides for Developing, Sharing and Experimenting the SDN projects with the help of P4 and OpenFlow
  • Link Emulation – each link has a data rate for shaping traffic which is enforced by Linux traffic control. The virtual Ethernet interface are unique for every emulated host
  • Isolation of Hosts – set of processes at the user level all transferred to a network namespace (providing interface, routing tables and Port ownership)
  • Emulated Switches – packet switching among different interfaces is possible using open Vswitch (in kernel mode) and Linux Bridge (default). Switches and routers can be run in both user and kernel space

The only points stated above are the characteristic features of mininet as a simulation and emulation tool. Accordingly, the best option for software defined networks simulation could be Mininet. With over 300+ successful projects in software defined networking, our engineers are completely experienced in all aspects of the field.

Usually, research scholars look for expert advice in handling the various aspects of Mininet. We have complete assistance on SDN projects to research scholars and students from top world universities. Along with the above benefits, now we would like to give you some ideas on the functions involved in mininet.


           There are several Mininet functions are used to deal with the SDN functions and some of the functions are as follows. Firstly, initialize the network with a set of simulation parameters. 

  • START () – this function is used to initialize the network
  • PINGALL () – this function is used for analysing the testing for all nodes
  • STOP () – this function is used to terminate the process of the network.


As we saw in the above sections, mininet can be used in SDN project simulation and can run a controller for different experiments. openvswitch and OVCS controller are present in default within mininet.

.sudo apt-get install POX/FloodLight

This is the command used for installing the suitable controller. The various useful mininet commands are listed below.

  • $ sudo mn – run mininet (as root) and minimal topology and command line interface are denoted in this. Open flow switch on controller among two hosts are also involved
  • sudo mn -h – it helps in viewing mininet help menu
  • mininet>nodes – current network nodes available for default topology is displayed
  • mininet>h1 ping h2 – connection between two hosts are tested with this command until the command is terminated
  • mininet >h1 ping -c1 h2 – connection among two different hosts in a packet are checked with this command
  • sudo mn -C – completely deletes the previous commands

Apart from these you get many different types of commands in mininet that is useful in SDN project design and development. We help you in implementing codes successfully and efficiently. The codes written by a researcher provide an idea of his expertise. So spend time writing crisp and the best codes. Now let’s talk about SDN mininet topologies.


The following topologies contained by mininet are useful in various aspects of SDN.

  • Single – contains k hosts and openflow switch and establishes connection among them.

#mn–topo single, 4

  • Linear – it has both k host and k switches (connection between them also established)

#mn–topo linear, 4

  • Minimal – it consists of two hosts and one openflow switch (link between them is also created)

#mn–topo minimal, 4

  • Reversed – reverse connection compared to single topology

#mn–topo reversed, 4

  • Tree – consists of k levels; two hosts per switch

#mn–topo tree, 3

Using these commands mentioned alongside each topology, you can easily design your own type of topology for SDN projects using mininet. Understanding various commands and their usage becomes an easy task with the support of our technical experts. Now we will give you some ideas on creating custom topology


Mininet provides various simple techniques for creating customized topology. You can easily write small python codes for such processes. The following are the advantages of using mininet for creating custom topology
