Abstract

Dans un mode de réalisation préféré, la présente invention concerne un procédé et un système permettant de concevoir et de vérifier une configuration de réseau physique (fig 3B), capable de supporter une configuration de réseau fonctionnelle (fig. 4B), sans faire appel au réel établissement de réseaux de ce type. La présente invention permet à un utilisateur d'entrer une conception de réseau matérielle et une conception de réseau fonctionnelle dans un système informatique (900). La conception de réseau fonctionnelle permet alors au système informatique d'établir un modèle de la trajectoire empruntée par les données pour passer d'un premier émetteur-récepteur à un second émetteur-récepteur par l'intermédiaire du réseau, tout en déterminant également les exigences de ressource telles que la largeur de bande, nécessaires pour supporter des flux de données de ce type via la conception de réseau matérielle. Après détermination des trajectoires pour chacune des connexions spécifiées dans la conception de réseau fonctionnelle, et détermination des exigences de ressource qui y sont associées, au niveau de chacun des dispositifs de matériel informatique, le système de la présente invention analyse les capacités de ressource maximales de chaque dispositif de matériel informatique par rapport aux ressources requises par ce dispositif, et détermine si la configuration matérielle peut supporter cette conception fonctionnelle. Dans un deuxième mode de réalisation, le système de la présente invention recommande d'apporter au matériel des modifications qui s'avèrent nécessaire pour supporter la conception fonctionnelle et vice versa. Dans un troisième mode de réalisation, un système informatique (1600) servant à mettre en application le système de la présente invention, configure les différents dispositifs du réseau spécifiés dans la conception de réseau matérielle en vérifiant si la conception matérielle supporte la conception fonctionnelle.
