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 The University of Johannesburg / College of Engineering, Science and Technology

The NetCOPE framework has proven itself as a viable framework for rapid development of hardware accelerated wire-speed network applications using Network Functions Virtualization (NFV). To meet the current and future requirements of such applications the NetCOPE platform has to catch up with upcoming 400 Gigabit Ethernet. Otherwise, it may become deprecated in following years. Catching up with 400 Gigabit Ethernet brings many challenges bringing necessity of completely different way of thinking. Multiple network packets have to be processed each clock cycle requiring a new concept of processing. Advanced memory management is used to ensure constant memory complexity with respect to the number of DMA channels without any impact on performance. Thanks to that, even more than 256 completely independent DMA channels are feasible with current technology. A lot of effort was made to create the framework as generic as possible allowing deployment of 400 Gigabit Ethernet and beyond. Emphasis is put on communication between the framework and host computer via PCI Express technology. Multiple Ethernet ports are also considered. The proposed system is prepared to be deployed on the family of COMBO cards, used as a reference platform.
