For any pair of individual objects (i, j) and each relationship that may exist therebetween, a management device comprises a memory element RMP(i, j) for storing the existence or absence of said relationship. The memory element comprises an input corresponding to a first object (i) and an input corresponding to a second object (j), said inputs being connected to two respective individual buses (CC(j), LC(i)). The two inputs must receive two respective simultaneous commands to enable data indicating the existence or absence of a relationship between the objects to be written into the element. In a preferred embodiment, the input corresponding to the first object must receive a read signal to enable the memory element to deliver the data to an output corresponding to the second object, and the input corresponding to the second object must receive a read signal to enable the memory element to deliver the data to an output corresponding to the first object. If the relationship is symmetrical, said memory elements are arranged in a triangular network (TN'). The device may be used in switching systems for asynchronous transfer mode telecommunications.

Pour tout couple de deux objets distincts (i, j), et pour chaque relation susceptible d'exister entre ces deux objets, le dispositif de gestion comporte un élément de mémoire RMP(i, j) pour mémoriser, soit l'existence, soit l'inexistence, de cette relation. Cet élément de mémoire comporte une entrée correspondant à un premier objet (i) et une entrée correspondant à un second objet (j), reliées à deux bus individuels (CC(j), LC(i)) correspondant respectivement à ces deux objets. Ces deux entrées doivent recevoir respectivement deux commandes simultanées pour écrire dans cet élément une information indiquant, soit l'existence, soit l'inexistence d'une relation entre ces deux objets. Selon un mode de réalisation préférentiel, l'entrée correspondant au premier objet doit recevoir un signal de lecture pour que l'élément de mémoire restitue cette information sur une sortie correspondant au second objet; et l'entrée correspondant au second objet doit recevoir un signal de lecture pour que l'élément de mémoire restitue cette information sur une sortie correspondant au premier objet. Ces éléments de mémoire sont organisés en réseau triangulaire (TN'), si la relation est symétrique. Application aux systèmes de commutation pour télécommunications à mode de transfert asynchrone.
