Abstract:

Currently, significant development of network technologies related to the design and management of network infrastructure can be observed in the world. One of the most important developed aspects is enabling a smooth response to changes in the network simultaneously with minimizing the associated control traffic. As a result, the network should operate without significant downtime. On the other hand, it does not involve high costs of implementing the changes in the network structure (e.g., regardless of chosen users, provided services, or send data type). Additionally, the mentioned changes should not involve the need for network reconfiguration. Software-defined networks (SDNs) are the appropriate solution for the described assumptions. This paper demonstrates the idea of a wireless local area network (WLAN) as the SDN. To this aim, we use the Mininet – WiFi tool with the Floodlight controller to manage this SDN. In carried out studies, we assessed the applicability of these management tools. We tested using them to manage the WLAN traffic and block the users, which generate significant traffic. The obtained results showed the reasonability of using the Mininet–WiFi tool with the Floodlight controller to manage the traffic in WLANs or other SDNs.
