Renforcer la capacité de survie des réseaux fédérateurs contre les pannes multiples devient une préoccupation commune parmi les entreprises de télécommunications qui doivent maintenir leurs services même en cas de catastrophe. Cet article présente un schéma de récupération après défaillance multiple qui prend en compte le fonctionnement et la gestion des chemins optiques. Le schéma présenté utilise l'escalade du schéma depuis la restauration pré-planifiée jusqu'au réacheminement complet. Premièrement, la capacité de survie de ce schéma face à des pannes multiples est évaluée en tenant compte des contraintes opérationnelles telles que la sélection de l'itinéraire, l'allocation des ressources et l'ordre de récupération des chemins défaillants. Les résultats de l'évaluation montrent que l'escalade du schéma offre un niveau élevé de capacité de survie même sous des contraintes opérationnelles, et cet article clarifie quantitativement l'impact de ces diverses contraintes opérationnelles. De plus, les fonctions fondamentales de l'escalade de schéma sont implémentées dans le plan de contrôle de commutation d'étiquettes multiprotocole généralisée et vérifiées dans un réseau basé sur une connexion croisée optique.

Abstract: Bolstering survivable backbone networks against multiple failures is becoming a common concern among telecom companies that need to continue services even when disasters occur. This paper presents a multiple-failure recovery scheme that considers the operation and management of optical paths. The presented scheme employs scheme escalation from pre-planned restoration to full rerouting. First, the survivability of this scheme against multiple failures is evaluated considering operational constraints such as route selection, resource allocation, and the recovery order of failed paths. The evaluation results show that scheme escalation provides a high level of survivability even under operational constraints, and this paper quantitatively clarifies the impact of these various operational constraints. In addition, the fundamental functions of the scheme escalation are implemented in the Generalized Multi-Protocol Label Switching control plane and verified in an optical-cross-connect-based network.
