A communication system using a network route establishing technique for a network having a plurality of nodes connected through links, in which a route search message is delivered simultaneously in a plurality of directions from a sender node through a network route to a destination node, and a confirmation is delivered from the destination through the network route back to the sender node, and accordingly, a network route is established. The communication system includes a device for detecting, at a node through which a search message is to be transmitted, a possibility of a transmission of the search message beyond the node, a device for delivering a cancel message in the direction from which the search message has been transmitted, and a device for releasing the network route engaged by the search message, based on the delivered cancel message.

L'invention est un système de communication qui utilise une méthode d'établissement de trajets dans un réseau ayant une pluralité de noeuds connectés par des liaisons. Un message de recherche de trajet est transmis simultanément à un noeud de destination dans une pluralité de directions par un noeud d'émission via un trajet de réseau et une confirmation est transmise du noeud de destination au noeud d'émission via ce trajet, ce qui établit un trajet dans le réseau. Le système de communication de l'invention comprend un dispositif servant à détecter à un noeud par lequel doit transiter un message de recherche la possibilité d'une transmission de ce message au-delà de ce noeud, un dispositif servant à transmettre un message d'annulation dans la direction d'où provient le message de recherche, et un dispositif commandé par le message d'annulation transmis qui sert à libérer le trajet utilisé par le message de recherche.
