Abstract: A method and a device for analyzing a consumption of resources in a computing infrastructure to predict a resource consumption anomaly on a computing device. The method includes determining a plurality of resource consumption modeling functions; determining a correlation between the resource consumption modeling functions; measuring a resource consumption by a measurement of a consumption value of a first resource; and predicting the resource consumption of the computing infrastructure. The predicting includes a calculation of a value of future consumption of a resource to be predicted from the consumption value of the first resource and from a previously calculated correlation between modeling functions.

Abstract: A method is proposed for the identification of a connected object in a network infrastructure which comprises at least two networks of connected objects interconnected by the intermediary of a data transport network. The method enables a connected object to search for and identify one or more other connected objects of the network infrastructure on the basis of specific search criteria. In particular, a connection gateway can, first, receive (201) and process (202) a request, which contains the search criteria, coming from a connected object and, secondly, transmit (203) to said connected object identification information for other connected objects that meet these criteria.

Abstract: The invention relates to a method for optimizing the use of gateways according to a category of message to be sent by a connected object capable of accessing several gateways.

Abstract: A method for evaluating the performance of an application chain within a computer infrastructure comprising a number N resources denoted Ri (1?i?N), where the method comprises the steps of: collecting over a same time interval with a same sampling period a predefined number M of series of measurements Xk (1?k?M) relating to the level of use of the resources; for all the possible combinations of two series of measurements (Xk1, Xk2), with k1?k2: creating a plurality of pairs of subsets (X?k1, X?k2) by selecting a predefined number nv of values based on the series Xk1 and Xk2; applying an algorithm for searching affine correlation relation(s) over each pair of subsets; calculating the percentages differences between the values of X?k2(t) and of aX?k1(t)+b for each index t (between 1 and nv); and calculating the saturation values of the series X?k2.
