Mininet Basics

Mininet provides a virtual test bed and development environment for SDN. Mininet networks run real code including standard Unix/Linux network applications as well as the real Linux kernel and network stack. Mininet provides an extensible Python API for network creation and experimentations. Ref: [MININET - Open Networking Foundation]


Mininet enables: rapid prototyping of software-defined networks, complex topology testing without the need to wire up a physical network, and multiple concurrent developers to work independently on the same topology.

Instances

  • Guest: official VM Mininet 2.2.2 on Ubuntu 14.04 LTS - 64 bit
  • POX 0.2.0 (carp)
  • OVS (Open vSwitch) 2.0.2
  • Host: VirtualBox 5.2.6 on Ubuntu Xenial 16.04.3.

Mininet Setup

  • Download a Mininet VM Image
  • Import the Image (eg. into VirtualBox)
  • Configure Access (eg. port forwarding or host-only networking)
  • Run the VM
  • Access via SSH with Remote Display Forwarding Enabled

Note: in the official Mininet VM image version 2.2.2, there is possibly a configuration bug if you’re using VirtualBox. See comments by isams1 in this thread. So don’t use host-only networking to access the VM.

MiniNAM

  • A utility that provides real-time animation of any network created by the Mininet emulator.
  • MiniNAM includes all the components required to initiate, visualize and modify Mininet network flows in real-time.
  • MiniNAM provides a graphical user interface that allows dynamic modification of preferences and packet filters: a user can view selective flows with options to color code packets based on packet type and/or nodes (hosts).

POX Controller

  • POX is a Python-based SDN controller platform geared towards research and education.
  • POX provides a framework for communicating with SDN switches using either the OpenFlow or OVSDB protocol. Developers can use POX to create an SDN controller using the Python programming language.
