Measuring the quality of the experience of users who contract streaming services is fundamental for the provider, since it allows them to measure the level of satisfaction of their service in the customers. However, the way to measure QoE through the MOS technique is quite manual and does not give information in real time. The present project presents an application that allows to approximate the QoS measurements (bandwidth and packet loss) taken in a SDN network in real time, process them and calculate an instantaneous MOS value, which generates a graph and an average MOS during the duration of the Streaming. This result is approximate to the user's actual MOS and allows the provider to anticipate problems that may be occurring on the network.
