Abstract
Process for controlling frames transporting data from a transmitting Terminal (DTE 1) to at least a receiving Terminal (DTE 2) through a plurality of consecutive nodes including a start access node (NODE 1) connected to said transmitting Terminal and at least an end access node (NODE 6) connected to said receiving Terminal and intermediary nodes (NODE 2 to NODE 5), with each data frame comprising one or several protocol layers respectively associated with one or several communication protocols of controlling the frame flow at each node; such a process consisting in adding to each data frame a Data Manipulation Layer (DML) defining the parameters necessary for managing the manipulation (compression and/or encryption) of each field of the data frame located after the DML, and adding to each data frame a Control message for transporting a control protocol defining new parameters to be used by some ones nodes for managing the communication flow through the consecutive nodes.
