Introduction to Mininet emulator for Software Defined Networks?

Step by Step Introduction to Mininet emulator for Software Defined Networks


       Mininet is a high-power controlling network emulator that supports the production of a network of virtual hosts, controllers, links, and switches. Mininet is a tool that abruptly creates virtual Software Defined Networks (SDN) on PC. Mininet creates and visualizes intricate topology with Mininet Python API. The networks run on real code, including standard Linux network applications and a Linux kernel network stack. Mininet is superior because of its speed, little time for booting, and helps design customizable topologies. Mininet saves cost because the emulators are much more cost-effective alternatively of testing with hardware devices. It supports research, development, testing, debugging, and prototyping. Using mininet, users can easily connect with real-world network devices and test the SDN devices using OpenFlow protocols. Wherefore, mininet enables:

      1.Rapid prototyping of SDN.

      2.Facilitates complicated topology testing for validating SDN networks without requiring the real-time wire-up as a physical network.

      3.Multiple concurrent developer/programmer works independently on the same topology according to their obligation.

    Features of Mininet

      1.Mininet provides the area to develop and check SDN applications without demanding a physical atmosphere

      2.Offering a network checkbed allows the development and testing of applications that are artifice OpenFlow protocols

      3.Mininet will be used while not programming conjointly, and it offers the flexibility to integrate python API, thereby paving the manner for making and experimenting with networks.

      4.Mininet encompasses a CLI(Command Line Interface) that is tuned into topology and OpenFlow, thereby permitting us to correct or run network tests for our applications.

    Advantages of Mininet

      1.Mininet is very fast and takes a compact time to boot.

      2.Smooth and Easy to install and use.

      3.Saves cost because the emulators are more efficient than testing with hardware devices.

      4.An additionally simple one to attach with real-world network devices.

      5.Mininet has its high handiness.

      6.Quickly reconfigurable and restartable.

    Limitations of Mininet

      1. Mininet-based networks cannot outstrip the CPU or bandwidth attainable on a single server.

      2. Mininet can’t be able to run on non-Linux compatible OpenFlow switches or their applications.
