In prior art, one of the problems of equivalent switching MPLS packets is that the transmission of MPLS packets is defined unidirectionally. The inventive method provides a solution to the problem in the form of a configuration which allows for bidirectional and 1:n unidirectional transmission (requiring a reverse LAN channel). Equivalent switching operations in the case of an error occurring when a working entity fails are administered in an efficient manner according to priority criteria and MPLS link information
La commutation de remplacement pour des paquets transmis par commutation par étiquette multi-protocole (MPLS), dans l'état actuel de la technique, pose le problème de la définition unidirectionnelle de la transmission des paquets MPLS. L'amélioration apportée par la présente invention consiste en une configuration qui permet de réaliser à la fois une transmission bidirectionnelle et une transmission unidirectionnelle 1:n (qui nécessite un canal de retour). Selon l'invention, les commutations de remplacement en cas d'erreur peuvent être gérées de manière efficace, en fonction de critères de priorité et d'informations de communication MPLS, en cas de perturbation sur la ligne de service.
