Title (EN) METHOD FOR PROTECTION OF ETHERNET TRAFFIC IN OPTICAL RING NETWORKS
(FR) PROCEDE DE PROTECTION D'UN TRAFIC ETHERNET DANS DES RESEAUX ANNULAIRES OPTIQUES
Abstract: front page image
(EN)A method for protecting Ethernet data packets transmitted over SDH/SONET traffic in a ring-like optical network formed by a number of nodes, the method includes utilizing MS-SPRING/BLSR system for SDH/SONET traffic protection and, in case of one or more network failures that result in at least one isolated node in the network, the method comprises preventing initiation of a squelching algorithm of the MS-SPRING/BLSR system with respect to the SDH/SONET virtual containers carrying the data Ethernet packets, while ensuring that the standardized use of byte J1 is prevented with respect to the same SDH/SONET virtual containers carrying the Ethernet packets.
(FR)L'invention concerne un procédé de protection de paquets de données Ethernet transmis via un trafic SDH/SONET dans un réseau optique de type annulaire formé d'une pluralité de nodes, ledit procédé comprenant l'utilisation d'un système MS-SPRING/BLSR pour la protection d'un trafic SDH/SONET et, dans le cas d'une ou de plusieurs défaillances de réseau entraînant la formation d'au moins un noeud isolé dans le réseau, le procédé prévoit d'empêcher le déclenchement d'un algorithme de réglage silencieux du système MS-SPRING/BLSR par rapport aux conteneurs virtuels SDH/SONET portant les paquets de données Ethernet, tout en garantissant que l'utilisation normalisée de bytes J1 est empêchée par rapport aux mêmes conteneurs virtuels SDH/SONET portant les paquets Ethernet.
