CA 2192794

A set of logical networks is established on top of a physical network. Next, a predefined objective function, closely related to the operation and performance of the physical network, which physical network is viewed as the set of logical networks, is optimized with respect to at least one set of decision variables. Finally, the decision variables in accordance with the optimization are used to control the operation of the overall network system. Each set of decision variables relates to a separate aspect of the invention. A method and device for partitioning physical transmission resources among logical networks is provided. There is also provided a method and device for distributing offered traffic load among routes interconnecting the nodes of the node pairs. Furthermore, a combination of the sets of decision variables relates to yet another aspect of the invention. Accordingly, a method and device for partitioning physical transmission resources among logical networks and distributing offered traffic load among routes interconnecting the node pairs is disclosed.

On établit un ensemble de réseaux logiques au-dessus d'un réseau physique. Ensuite, on optimise, par rapport à au moins un groupe de variables de décision, une fonction objective prédéterminée intimement liée au fonctionnement et aux performances du réseau physique, ce dernier étant considéré comme étant l'ensemble de réseaux logiques. Enfin, on utilise les variables de décision suivant l'optimisation pour commander le fonctionnement de l'ensemble du système du réseau. Chaque groupe de variables de décision se rapporte à un aspect particulier de l'invention. On a prévu un procédé et un dispositif de répartition de ressources physiques de transmission parmi des réseaux logiques. On a également prévu un procédé et un dispositif de distribution du volume de trafic offert entre différents parcours reliant entre eux les noeuds de paires de noeuds. En outre, une association des groupes de variables de décision représente un autre aspect de l'invention. Par conséquent, on décrit un procédé et un dispositif de répartition de ressources physiques de transmission parmi des réseaux logiques, et de distribution du volume de trafic offert entre différents parcours reliant entre eux les noeuds de paires de noeuds.
