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, at least an end access node (NODE 6) connected to said receiving Terminal and optional intermediary nodes (NODE 2 to NODE 5), with each data frame comprising one or more protocol layers respectively associated with one or more communication protocols for controlling the frame flow at each node;said process comprising: a) adding to each data frame a Data Manipulation Layer (DML) defining the parameters necessary for managing the manipulation (compression and/or encryption) of a plurality of fields of said data frame, the DML providing each of said plurality of fields a manipulated data header (MDH), each MDH associated with a field and defining a manipulation mode for said associated field, such that each of said plurality of fields may be manipulated separately; and b) adding to each data frame a Control message for transporting a control protocol defining new parameters to be used by some ones of said plurality of nodes for managing the communication flow through said plurality of consecutive nodes.
