A method for managing data stream exchanges in an autonomic telecommunications network including a first phase consisting in extracting from each stream routing data and data for measuring the transfer function between at least one data producer Pi and at least one data consumer Cj, sharing the extracted routing data between processing and decision-making functional modules distributed across the said network, selecting at least one decision-making or processing module for which the access time to the measuring data of the transfer function is minimal, dynamically defining by at least one of the selected modules the said rules for optimizing the transfer settings of the stream according to the said measuring data and distributed over the said network select processing modules located on the path of the said streams in order to apply the said rules.
