Abstract

La présente invention concerne un dispositif de détection de boucles produit par un commutateur source (AS) lors de l'établissement d'un itinéraire d'acheminement aboutissant à un commutateur de destination (ES). En l'occurrence, le dispositif de détection de boucles est une cellule de rebouclage (20) comportant un commutateur source (AS), non seulement dans la zone source (21), mais aussi dans la zone renvoi (22).
