The web site indicates that the tool can support thousands of virtual nodes on a single operating system. Mininet is most useful to researchers who are building SDN controllers and need a tool to verify the behavior and performance of SDN controllers. Knowledge of the Python scripting language is very useful when using Mininet.
The Mininet project provides excellent documentation and, judging from the activity on the Mininet mailing list, the project is actively used by a large community of researchers.

Mininet/mininet. OpenFlow Tutorial - OpenFlow Wiki. Welcome to the OpenFlow tutorial! OpenFlow is an open interface for remotely controlling the forwarding tables in network switches, routers, and access points. Upon this low-level primitive, researchers can build networks with new high-level properties. For example, OpenFlow enables more secure default-off networks, wireless networks with smooth handoffs, scalable data center networks, host mobility, more energy-efficient networks and new wide-area networks – to name a few. This tutorial is your opportunity to gain hands-on experience with the platforms and debugging tools most useful for developing network control applications on OpenFlow.

Pre-requisites Stuck? Reproducing Network Research | network systems experiments made accessible, runnable, and reproducible. Videos · mininet/mininet Wiki. Overview - Mininet. Mininet is a network emulator which creates a network of virtual hosts, switches, controllers, and links. Mininet hosts run standard Linux network software, and its switches support OpenFlow for highly flexible custom routing and Software-Defined Networking.
Mininet supports research, development, learning, prototyping, testing, debugging, and any other tasks that could benefit from having a complete experimental network on a laptop or other PC. Mininet: Mininet provides an easy way to get correct system behavior (and, to the extent supported by your hardware, performance) and to experiment with topologies. Mininet networks run real code including standard Unix/Linux network applications as well as the real Linux kernel and network stack (including any kernel extensions which you may have available, as long as they are compatible with network namespaces.)
How it Works Nearly every operating system virtualizes computing resources using a process abstraction. Why it’s better Limitations. Teaching and Learning with Mininet · mininet/mininet Wiki. Tutorial at SIGCOMM 2014 SIGCOMM 2014 Tutorial: Teaching Computer Networking with Mininet Course Projects The following programming assignments are based on the ones we use in Stanford CS144 'An Introduction to Computer Networks'. Mininet is used to emulate the network topology in these assignments. Simple Router - Implementing a simple IP routerNetwork Address Translator (NAT) - Implementing a simple Network Address TranslatorPee-Wee OSPF (PWOSPF) - Implementing a simple link state routing protocol Lab Exercises BufferBloat - A simple (potentially in-class) lab exercise to observe the buffer bloat problem using Mininet Security Demo MAC Address Table Overflow Attack - A demonstration on MAC address table overflow attackDHCP Masquerade Attack - A demonstration of DHCP masquerade attackBGP Path Hijacking Attack Demo - A demonstration of BGP path hijacking attack Reproducible Network Research Experiments If you have developed assignments using Mininet, please feel free to add to this page.
Sample Workflow - Mininet. Mininet enables you to quickly create, interact with, customize and share a software defined network prototype, and provides a smooth path to running on hardware. This page illustrates the basic Mininet workflow, and many additional details are available in the Mininet walkthrough, the OpenFlow tutorial, and Mininet documentation. Creating a Network You can create a network with a single command. For example, sudo mn --switch ovsk --controller ref --topo tree,depth=2,fanout=8 --test pingall starts a network with a tree topology of depth 2 and fanout 8 (i.e. 64 hosts connected to 9 switches), using Open vSwitch switches under the control of the OpenFlow/Stanford reference controller, and runs the pingall test to check connectivity between every pair of nodes.
(This takes about 30 seconds on my laptop.) Interacting with a Network Mininet’s CLI allows you to control, and manage your entire virtual network from a single console. Mininet> h2 ping h3 tells host h2 to ping host h2’s IP address. Download/Get Started with Mininet - Mininet. The easiest way to get started is to download a pre-packaged Mininet/Ubuntu VM. This VM includes Mininet itself, all OpenFlow binaries and tools pre-installed, and tweaks to the kernel configuration to support larger Mininet networks. (These instructions are for Mininet 2.1.0 - for earlier versions, go to the bottom of this page.) Option 1: Mininet VM Installation (easy, recommended) VM installation is the easiest and most foolproof way of installing Mininet, so it’s what we recommend to start with. Follow these steps for a VM install: Download the Mininet VM image (2.1.0 or 2.0.0.
(In addition to the above resources, we’ve prepared a helpful Mininet FAQ as well as Documentation which you can refer to at any time!) Once you’ve completed the Walkthrough, you should have a clear idea for what Mininet is and what you might use it for. Option 2: Native Installation from Source This option works well for local VM, remote EC2, and native installation. Git clone. Mininet-discuss Info Page. Open-Source Routing and Network Simulation | Tag Archive | mininet. The easiest way to get started using the Mininet network simulator is to use the Mininet virtual machine. It is based on the Ubuntu Linux Server operating system and comes with all the software and tools required to support Mininet already installed.
The Mininet web site provides detailed setup notes, describing how to download and use the Mininet virtual machine. While I was following the procedure described in these notes, I found a few points where some more information would have been helpful. For my own reference, and to help anyone else who will install Mininet, I list the procedure I followed in the post, below.
