A method allowing execution of transmission functions hosted in intermediate pieces of equipment of a path established between two pieces of communication equipment. End-to-end encryption systems are designed to resist any surveillance or tampering attempt, as no third party can decrypt or modify the communicated data. There is a solution which, depending on the connection opening requests of the applications, allows to select and assemble the transport protocols necessary for the operation of the application. However, this method is local: this protocol stack is only assembled at the pieces of communication equipment constituting the ends of the connections. Consequently, the requests emitted by these applications are not transmitted to the intermediate pieces of equipment which host the desired functions. The method allowing execution of transmission functions allows to re-establish cooperation between pieces of communication equipment, constituting the ends of a connection, with intermediate nodes hosting transmission functions.
