  • Patent number: 10027557
    Abstract: Provided is a method for controlling exchanges of data streams between at least one source connected to a hybrid wide area telecommunication network via a local area access network and at least one recipient connected to the wide area telecommunication network via a remote access network. The method includes the steps of: setting new transfer rules through the analysis of the streams, dynamically creating at least one additional stream exchange path from the new transfer rules and the access rules in force, applying on the additional path burn-in, securization and optimization mechanisms for the stream transfers between the local area access network and the remote access network, and transferring each new stream to the recipient via the additional path according to the new transfer rules.

  • Patent number: 7333434
    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.
