The QoS measures on Transport Networks course aims to provide trainees with the necessary knowledge for the performance of proper valuation on Transport Networks. Starting from the parameters defined by the ITU Recommendations to measure the transmission quality, thresholds for acceptable, degraded, and unacceptable quality will be discussed. Furthermore, this training covers the quality indicators measurement for new transport modes, from MPLS to Carrier Ethernet, to the Data, Voice, and Video Real-Time packet routing.
To support the theoretical part of the training, we will show the results of several tests performed on different types of networks, such as VoIP traffic analysis depending on loss, latency, and jitter variables. To check the information quality at the highest layers, different encoded voice flows are reproduced and compared, also the error impact on video content is simulated.
