Prediction of a metric of quality of a network

An apparatus for building a prediction model adapted to predict a value of a metric of a quality of a point-to-multipoint telecommunications network, the apparatus comprising means for:

• Collecting a plurality of high-paced telemetry traffic measurement values representing traffic rates observed in a shared medium of the point-to-multipoint telecommunications network, wherein the shared medium is shared by a plurality of users of the point-to-multipoint telecommunications network and wherein the high-paced telemetry traffic measurement values represent traffic rates attributed to individual users among the plurality of users,
• Fitting at least one traffic model using the plurality of high-paced telemetry traffic measurement values and computing at least one simulated value of the metric of the quality of the point-to-multipoint telecommunications network using the traffic model and a descriptor of at least one network configuration, wherein the metric of the quality of the point-to-multipoint telecommunications network relates to at least one individual user of the point-to-multipoint telecommunications network,
• Training a prediction model on a simulated dataset, wherein the simulated dataset comprises the descriptor of at least one network configuration and the at least one simulated value of the metric of the quality of the point-to-multipoint telecommunications network, the prediction model being configured to compute the value of the metric of the quality of the point-to-multipoint telecommunications network.
