Abstract: A dynamic optimization process of a quality of service (QoS) in a data transmission packet network. The data transmission packet network includes a plurality of sources and a plurality of destinations connected to a transit network by a plurality of access networks. Each source is configured to send data at a maximum data rate and each destination is configured to receive a maximum transmission data rate. The sources each includes a classification and a control device configured to control a transmission data rate of transmitted data. The process is characterized in that the absolute transfer delay period, the jitter, the output of the exchanged data and the losses between each source S and each destination D are measured, and the classification and control means of the output are monitored.
