Modeling of OpenFlow based software defined networks using Mininet

Software-defined networking (SDN) has become one of the most important architectures for the management of large scale complex networks, which may require re-policing or re-configurations from time to time. By decoupling the control plane from data plane, SDN achieves easy re-policing. Hence, the network switches or routers forward packets simply by following the flow table rules which are set by the control plane. OpenFlow is the most popular SDN protocol or standard and has a set of design specifications. SDN or OpenFlow is a relatively new area, and it has attracted both academia and industry. This research work uses a network emulation tool called ‘Mininet’, for the implementation of SDN using OpenFlow. This tool allows to create the virtual switches, hosts, controllers and links. Using all these components, a network of the desired topology and scale can be created. The focus of this research is to update the labs created for the coursework in Electrical and Computer Engineering department. The tools used in the labs are outdated and are required to be changed, tested and presented. In addition, new labs with new concepts have also been added.
