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. The method includes in particular: a discovery procedure (100) comprising broadcasting (120), by the connected object, a query message (BCM), and receiving (130), by the connected object, response messages (131, 132) sent by each of the available gateways in response to the query message (BCM); a procedure (200) for assigning priority levels to the available gateways per category of message to be sent; and a procedure for ranking (300), by the connected object, the available gateways in order of their respective priority levels depending on the category of message to be sent, with the objective of choosing one of said available gateways for sending data messages.

Abstract: A method for dynamic routing in a network of connected objects is proposed comprising at least two connection gateways to at least one data transport network. In particular, the method which makes possible for each connection gateway of a network of connected objects to recognize, in real-time, changes in its environment, and to select the message transmission path from one connected object to another that is associated with an optimal level of (transmission) performance.

Abstract: The invention relates to a method and a device for analyzing a consumption of resources in a computing infrastructure for the prediction of a resource consumption anomaly on a computing device, said method comprising:—a step (200) of determining a plurality of resource consumption modeling functions (MF); a step (300) of determining a correlation between said resource consumption modeling functions; a step (400) of measuring a resource consumption, said step comprising the measurement of a consumption value of a first resource; and a step (500) of predicting the resource consumption of the computing infrastructure, said prediction step comprising 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 (MF).

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: A dynamic routing method in interconnected networks of connected objects is hereby proposed. The purpose of the method is the generation and maintenance, by a connection gateway of a network of connected objects, of a routing list used by said connection gateway for its routing functions. Additionally, the method enables a connection gateway to select the most appropriate transmission path for transmitting a message from a source connected object to a receiving connected object within a network infrastructure formed by at least two networks of connected objects and a data transport network interconnecting them.

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.
