Abstract

L'invention concerne un système et un procédé pour l'affectation d'étiquettes à commutation d'étiquette multiprotocole (MPLS) sur des connexions de transport par réseau optique synchrone/hiérarchie numérique synchrone (SONET/HNS). Le système et le procédé reposent sur les étapes suivantes: (1) classification des paquets; et (2) mappage des paquets à même classe d'équivalence vers l'avant sur la même connexion nxVT. Selon une variante, le mappage consiste à (a) associer une certaine largeur de bande de connexion entre un routeur externe et un multiplexeur à insertion/extraction, entre un noeud d'origine et un noeud de destination; et (b) à créer une connexion nxVT entre les noeuds d'origine et de destination - et à établir ainsi un trajet de commutation d'étiquette entre les noeuds d'origine et de destination. Selon une autre variante, le procédé et le système se caractérisent par le mappage de paquets ayant la même étiquette MPLS sur la même connexion nxVT.
