Abstract

L'invention se rapporte à un procédé de mise en oeuvre d'une connexion de communication entre un premier ordinateur (11) et un second ordinateur (21) faisant office de noeuds dans un réseau (1). La mise en oeuvre dudit procédé nécessite un troisième ordinateur (31) qui est relié au réseau. Le second ordinateur comporte un dispositif de commande (41) conçu pour recevoir un signal de commande (46) émis par un dispositif de communication (33) relié au troisième ordinateur par l'intermédiaire, de préférence, d'un canal de communication radio (45). En réponse au signal de commande (46), le dispositif de commande (41) démarre un processus d'initiation exécuté par le second ordinateur (21). Ceci implique une connexion du second ordinateur (21) au réseau, et donc un transfert sur le réseau des informations relatives à l'adresse du second ordinateur (21), vers le premier ordinateur (11) et par l'intermédiaire du troisième ordinateur (31), une connexion directe entre le premier ordinateur (11) et le second ordinateur (21) pouvant être établie sans la participation du troisième ordinateur (31).
