Patent ID: 7804779

Claim:
Method for remotely controlling congestion of meshed flow exchanged in a packet mode telecommunication network between a number N of central sites C i provided with active devices for managing flow and a number M of remote sites D m devoid of such devices, said central sites exchanging between them information intended specifically for managing the flow exchanged between each of the central sites and each of the remote sites, the method comprising the following steps: dynamically associating each remote site to a subset of central sites according to actual traffic observed, establishing a dynamic traffic matrix indicating, for each remote site, the group of central sites exchanging data with this remote site during a given observation period, the establishment of the dynamic traffic matrix being executed periodically during a first processing loop having a duration configured to establish an aggregate traffic matrix that takes into account the superposition of all of the traffic types during said period, exchanging between the different central sites of each group of minimal information on real time traffic with each of said remote sites, the exchanges of information between the central sites and the definition of a local image that indicates the state of pre-congestion being executed periodically during a second processing loop having a duration configured to establish a traffic matrix in real time in such a way as to detect in real time the different states of congestion, defining using the information exchanged in the previous step a local image indicating the state of pre-congestion for the traffic of each remote site, calculating rules for managing traffic exchanged with each remote site according to the image defined in the previous step; the method characterized in that the calculation of the rules for managing traffic is executed periodically during a third processing loop having a very short duration in relation to the execution durations of the first and second processing loops in such a way as to adjust the traffic in real time according to the type and quantity of flow exchanged between the central sites and the remote sites.
