Install Mininet from source code on Ubuntu 16.04

Mininet

Mininet is a lightweight software defined network and testing platform; it uses lightweight virtualization technology to make a single system look like a complete network running related kernel system and user code. It can also be simply understood as a process-based virtualization platform in the SDN network system. It supports various protocols such as OpenFlow and OpenvSwith. Mininet can also simulate a complete network host, link and switch on the same computer and facilitate interactive development, testing and demonstration, especially those using OpenFlow and SDN technology; at the same time, the code under this process virtualization platform can also be migrated to the real environment.

Features of Mininet

• It can easily and quickly create a user-defined network topology, shortening the development and testing cycle.
• Can run real programs. Basically, programs that run on Linux can run on Mininet, such as Wireshark
• Mininet supports OpenFlow, and the code running on Mininet can be easily ported to hardware devices that support OpenFlow.
• Mininet can be run on your own computer, a server, a virtual machine, or the cloud (such as Amazon EC2).
• Mininet provides Python API, which is simple and easy to use
• Mininet is an open source project, the source code is here: https://github.com/mininet

Install Mininet

Get the source code

git clone git://github.com/mininet/mininet

Enter the directory

cd mininet

Complete Installation

./util/install.sh -a

This is the first installation. I don't know what information to configure. It is recommended to install it completely.

test

sudo mn --test pingall

Check the mininet version

mn --version

Other installation commands

# install.sh –a ##Complete installation (installed in the home directory by default)
# install.sh -s mydir –a ##Complete installation (installed in another directory) 
# install.sh –nfv ##Install Mininet + user switch + OVS (installed in the home directory)    
# install.sh -s mydir –nfv ##Install Mininet + user switch + OVS (install in other directories)

Creating a super simple data center network

Data center networks typically have a tree topology. End hosts connect to top-of-rack switches, which form the leaves (edges) of the tree; one or more core switches form the root; and one or more layers of aggregation switches form the middle of the tree. In a basic tree topology, each switch (except the core switch) has a single parent switch. Additional switches and links can be added to construct more complex tree topologies (eg, fat trees) in an effort to improve fault tolerance or increase inter-rack bandwidth.

In this assignment, your task is to create a simple tree topology. You will assume that each level, core, aggregation, edge and host, consists of a single layer of switches/hosts with a configurable fan-out value (k), looking like:
