1. A method for managing data stream exchanges in an autonomic telecommunications network including a central module intended to establish a global policy defining the rules for transfer of streams in the said network between multiple data producers P i and multiple data consumers C j connected to the said network via multiple functional elements distributed across the said network, where the said functional elements include at least one module for processing the said streams intended to optimise the settings of the stream transfer over the network, and at least one decision-making module intended to define dynamically rules for optimising the said transfer settings, a method characterised in that it includes a first phase consisting in: a—extracting through the said processing modules of each stream exchanged across the network routing data and measuring data of the transfer function between at least one data producer P i and at least one data consumer C j. b—sharing the extracted routing data with the said decision-making modules, c—selecting at least one decision-making or processing module for which the access time to the measuring data of the transfer function is minimal, and a second phase consisting in: d—dynamically defining by at least one of the selected modules the said rules for optimising the stream transfer settings according to the said measuring data, e—selecting processing modules located on the path of the said streams in order to apply the said rules such that the stream transfer function is made consistent with the global stream exchange policy defined by the central module. f—applying the said rules by the modules selected in step e).
