Patent ID: 7333434

Claim:
A dynamic optimization process of a quality of service (QoS) in a data transmission packet network, wherein said 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, wherein each source is configured to send data at a maximum data rate L max, x, d , and each destination is configured to receive a maximum transmission data rate L max, x, d , wherein said sources each includes a classification and a control device configured to control a transmission data rate of transmitted data, the process comprising: (a) measuring an absolute transfer delay period, a jitter, a transmission data rate of exchanged data, and losses between each source and each destination, and carrying out, based on the measures obtained: (a1) for each destination distributing the maximum transmission data rate L max, s, x among the different sources; (a2) for each destination, determining dynamically an access network congestion point limit that optimizes the maximum transmission data rate L max, x, d ; (a3) for each source, determining dynamically an access network congestion point limit by optimizing the maximum transmission data rate L max, s, x and a maximum transmission data rate towards each destination L max, s, d ; (a4) for each source, determining an impact of congestion on the transit network; and (b) monitoring the classification and the control of the data rate depending on results from (a1), (a2), (a3), and (a4).
