Abstract: front page image
(EN)Disclosed is a fault protection method in the field of communication technologies, comprising: creating an operating path and a protection path for a service, thus forming 1+1 protection, and creating a shared mesh recovery path separate from the operating path and the protection path; and forming the 1+1 protection by the remaining two normal paths when any one of the three, the operating path, protection path, or shared mesh recovery path, is faulty. Also disclosed is a fault protection device.
(FR)La présente invention porte sur un procédé de protection contre les défaillances dans le domaine des technologies de communication, comprenant : la création d'un chemin de fonctionnement et d'un chemin de protection pour un service, formant ainsi une protection 1+1, et la création d'un chemin de récupération à maillage partagé distinct du chemin de fonctionnement et du chemin de protection, et la formation de la protection 1+1 par les deux chemins normaux restants lorsque l'un quelconque, parmi le chemin de fonctionnement, le chemin de protection ou le chemin de récupération à maillage partagé, est défectueux. L'invention concerne également un dispositif de protection contre les défaillances.
