Simulating and prototyping software defined networking (sdn) using mininet approach to optimise host communication in realistic programmable networking environment optimise host communication in realistic programmable networking environment.

This is a Masters student Final Dissertation / In this project, two tests were performed. On the first test, Mininet-WiFi was used to simulate a
Software Defined Network to demonstrate Mininet-WiFi’ s ability to be used as the Software
Defined Network emulator which can also be integrated to the existing network using a Network
Virtualized Function (NVF). A typical organization’s computer network was simulated which
consisted of a website hosted on the LAMP (Linux, Apache, MySQL, PHP) virtual machine, and
an F5 application delivery controller (ADC) which provided load balancing of requests sent to the
web applications. A website page request was sent from the virtual stations inside Mininet-WiFi.
The request was received by the application delivery controller, which then used round robin
technique to send the request to one of the web servers on the LAMP virtual machine. The web
server then returned the requested website to the requesting virtual stations using the simulated
virtual network. The significance of these results is that it presents Mininet-WiFi as an emulator,
which can be integrated into a real programmable networking environment offering a portable,
cost effective and easily deployable testing network, which can be run on a single computer. These
results are also beneficial to modern network deployments as the live network devices can also
communicate with the testing environment for the data center, cloud and mobile provides.
On the second test, a Software Defined Network was created in Mininet using python script. An
external interface was added to enable communication with the network outside of Mininet. The
amazon web services elastic computing cloud was used to host an OpenDaylight controller. This
controller is used as a control plane device for the virtual switch within Mininet. In order to test
the network, a webserver hosted on the Emulated Virtual Environment – Next Generation (EVENG)
software is connected to Mininet. EVE-NG is the Emulated Virtual Environment for
networking. It provides tools to be able to model virtual devices and interconnect them with other
virtual or physical devices. The OpenDaylight controller was able to create the flows to facilitate
communication between the hosts in Mininet and the webserver in the real-life network / The University of South Africa
