Abstract: 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.

Abstract: A tool for aiding management of a communicating physical device includes: a device controller operating the physical device using operating parameters; a data storage interlinking an identifier from the physical device and dated values of attributes and a list of control functions capable of modifying some of the operating parameters; an interpreter adapted for receiving a device identifier datum and a time horizon parameter at the same time and for responding thereto by establishing a series of respective events using the information from the data storage, related to the time horizon, each event interlinking a date, one or more identifiers of control functions, and parameters for these functions, established in accordance with a dated attribute value; and a sequencer arranged to call the interpreter and carry out chronologically the calls of the functions of each event of the series as returned by the interpreter.
