Constraint-based model for network service provisioningModele base sur les contraintes pour la gestion des services reseau

As the network services deployed over the Internet become more complex, their configurations are more difficult to manage. The constraints that exist among the network service configuration parameters are an important source of complexity in the configuration, validation and fault management processes. Existing solutions do not provide adequate high-level models to capture and integrate various types of configuration constraints. It is therefore necessary to adopt a structured approach in order to solve this problem. Thus, in this paper, we propose a structured and integrated constraint-based model for network service configuration, validation and fault management.
