TOOL FOR MANAGING COMPUTER RESOURCES AND INFRASTRUCTURES AND NETWORKS

A tool for assisting the operation of a network of interconnected physical equipment includes a physical infrastructure manager associated with a first data structure in which the equipment items are registered under a resource identifier in relation to a first sequence of dated values of global utilizable functional capacity, and a virtual infrastructure manager associated with a second data structure in which virtual units are registered under a unit identifier in relation to a second sequence of dated values of global utilizable functional capacity, and with a third data structure in which a virtual unit identifier is associated with a group of resource identifiers and hence with the corresponding sequences of dated capacity values. The virtual infrastructure manager dynamically reconfigures a virtual infrastructure object in accordance with the rights and capacities requested by a user.
