Factors, such as an increase in multimedia services, combined with a rise in the number of terminals and their data consumption are creating a need to transmit more traffic volume. This might mean, a traffic overload in the telecommunications networks in the not-toodistant future. Hence, it will be necessary to create a new way to transmit information more optimally to solve this possible future problem. For this reason, SDN (Software Defined Networking) is having a huge impact and is greatly valued in the field of networks, due to its great advantages when compared to the operation of conventional networks, such as separating the control layer with the data layer. The proposed project in the following document works as a real-time monitoring tool for SDN networks. This platform is especially useful for network operators that offer a service based on an SDN controller for the transport of their clients’ information. For this reason, there will also be a need to monitor the network and its connected devices. As we use a monitoring platform we can know the status and relevant information in real-time. We have created a simulation of an SDN network as a model to generate traffic, with which it will be possible to understand the operation of the monitoring platform. We can also move it to complex networks in possible future purposes. As shown by the results, interesting statistics about the switches and their interfaces will be shown. We can use it to check their availability and compare the traffic between interfaces, or to be informed about the different active flows transmitted between hosts. These are one of the visualizations, among others, which will be grouped and represented on dashboards.
