Abstract

L'invention concerne un système de traitement d'informations comprenant : un terminal utilisateur qui communique avec un serveur par l'intermédiaire d'un premier dispositif de relais, d'un second dispositif de relais, et d'un troisième dispositif de relais ; un dispositif de coordination ; et un dispositif de commande. Le dispositif de coordination comprend une unité fonctionnelle de coordination qui notifie au dispositif de commande des informations de notification comprenant des premières informations d'identification pour identifier le premier dispositif de relais, qui stocke une session établie avec le terminal utilisateur, des informations d'identification de tranche pour identifier une tranche correspondant à la session, et des informations d'adresses attribuées au terminal utilisateur. Le dispositif de commande comprend une unité fonctionnelle d'établissement de mappage qui, sur la base des informations de notification, génère une règle de distribution dans laquelle une ressource d'un premier segment entre le premier dispositif de relais et le second dispositif de relais, et une ressource d'un second segment entre le second dispositif de relais et le troisième dispositif de relais sont attribuées aux informations d'adresses, et établit la règle de distribution pour le second dispositif de relais et le troisième dispositif de relais.
