Announcing Mininet 2.1.0 !

We are pleased to announce the immediate availability of Mininet 2.1.0 on !

Mininet is a network emulation platform that is intended to be the quickest, easiest, and most enjoyable way to create virtual networks for research, education, and system development. By providing an instant virtual network on your laptop that can run real application, switch, and controller code, Mininet also makes it convenient to get started with SDN and OpenFlow without any additional hardware.

Mininet 2.1.0 provides a number of bug fixes as well as new features, including:

  • Convenient access to Mininet() as a dict of nodes
  • X11 tunneling (wireshark in Mininet hosts, finally!)
  • Accurate reflection of the Mininet() object in the CLI
  • Automatically detecting and adjusting resource limits
  • Automatic cleanup on failure of the mn command
  • Support for installing the OpenFlow 1.3 versions of the reference user switch and NOX from CPqD and Ericsson
  • Preliminary support for running OVS in user space mode
  • Preliminary support (IVSSwitch()) for the Indigo Virtual Switch
  • Preliminary support for Fedora in
  • A script (util/m) for easily running new shells or commands in nodes
  • The ability to import modules from mininet.examples

We have provided several new examples (which can easily be imported to provide useful functionality) including:

  • Modeling separate control and data networks: mininet.examples.controlnet
  • Connecting Mininet hosts to the internet (or a LAN) using NAT: mininet.examples.nat
  • Creating per-host custom directories using bind mounts: mininet.examples.bind

Note that examples contain experimental features which might “graduate” into mainline Mininet in the future, but they should not be considered a stable part of the Mininet API!

Additional information may be found in the Release Notes.

Mininet is an open source project, and we are grateful to our many code contributors, bug reporters, and active users who continue to help make Mininet a useful system with a friendly and helpful community!

Have fun with Mininet!
