resource management system for a network of communications inter-node connections to shared resources associated preemption rights and priority of access to resources

A device (D) is dedicated to the management of resources in a communications network comprising nodes (LER, LCR) interconnected by connections. This device (D) comprises management means (MG) to define connections and link them to resources so that they can be established if necessary. The management means (MG) are further charged to associate each connection, according to a selected criterion, either a first state in which it has a right of first refusal on selected resources shared at least partially with at least one further connection, without being authorized to use them, or a second state wherein it is allowed to use the resources selected in view of its property.
