Method and Device for Remotely Controlling the Congestion of Meshed Flow in a Packet Mode Telecommunication Network

Method for remotely controlling the congestion of meshed flow exchanged in a packet mode telecommunication network between a number N of central sites Ci (12) provided with active devices for managing flow and a number M of remote sites Dm (14) devoid of such devices, said central sites (12) exchange between them information intended specifically for managing the flow exchanged between each of the central sites (12) and each of the remote sites (14), method characterised in that it comprises the following steps:

• dynamically associating each remote site (14) to a subset of central sites (12) according to actual traffic observed,
• establishing a dynamic traffic matrix indicating, for each remote site (14), the group of central sites (12) exchanging data with this remote site (14) during a given observation period,
• exchanging between the different central sites (12) of each group of minimal information on the real time traffic with each of said remote sites (14),
• 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 (14),
• calculating the rules for managing traffic from (respectively to) each remote site (14) according to the image defined in the previous step.
