Introduction & Installation of Mininet

Introduction of Mininet

Mininet is a powerful network simulation platform, through this platform, we can easily simulate the real environment of the network operation and architecture. Current Sdn/openflow development in full swing, but in the real network can not carry out related network experiments, natural need a simulation platform can to this new network architecture, and Mininet came into being, undertook this glorious and arduous mission.

The mininet comes with this switch, host, controller, and can be installed on Mininet Openvswitch, multiple controllers (nox\pox\ryu\floodlight\ Opendaylight, Mininet can run on a variety of operating systems (Windows\linux\mac OS), with strong system compatibility. The most exciting thing is: the experiments carried out on the mininet can be seamlessly moved to the real environment (this has not been tried, just see Mininet official website is so said, hope that the successful transplant operation of the great God can be generous enlighten).

The installation of the Mininet Mininet is divided into two types: one is to download and install the virtual machine image of the mininet directly from the Internet, and then the installation on VMware or virturebox can be used, it is also very convenient.

The steps are as follows: Step one: Get mininet source code:

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

With this command you can get the latest version of Mininet, if you want to get the previous version of Mininet, you can use the following command:

git clone git://github.com/mininet/mininetgit checkout -b 2.1.0p1 2.1.0p1

Step Two: Install Mininet (The following command is optional):

mininet/util/Install.sh-a  Everything you need to install mininet in the home directory, including Open VSwitch, Wireshark, and pox

mininet/util/Install.sh-s Mydir-a All the things that are required to install mininet in the specified directory

mininet/util/INSTALL.SH-NFV install mininet, OpenFlow recommended switches and open VSwitch in the home directory

mininet/util/Install.sh-s MYDIR-NFV Install mininet, OpenFlow recommended switches and open VSwitch in the specified directory

Step three: Post-installation tests:

sudo mn --test pingall

By this command, if the installation succeeds, it will be successful by pinging all the hosts. If this step is passed, the Mininet installation will succeed, and the relevant test experiment can be carried out in mininet.
