The invention relates to a method for synchronizing interconnected critical devices comprising servers and clients, each critical device being connected to another critical device by a virtual link, each termination of which is associated with a minimum and a maximum value of transmission time for a data packet, the method, implemented periodically, comprising:

System for synchronizing a set of interconnected avionics devices with communication network of a vehicle

A testing method including defining a plurality of test periods, and for each current test period collecting flight data from at least two separate avionics systems operating independently, analyzing consistency between the data collected during the previous test period, and/or between the data and flight data collected during an earlier test period, while verifying a plurality of predetermined consistency rules, and when at least one of these rules is not verified, generating an alert relative to a loss of integrity of the avionics.

Method for testing the integrity of the avionics of an aircraft, associated device and computer program product

A method for controlling communications within an ad hoc mobile network includes a plurality of terminals having the slave function and/or the master function, said slave terminals also including a slave orchestration system, said master terminals also including a master orchestration system. The slave orchestration system includes at least one network test module, a module for controlling communications, and a database of communications to be set up and an administration module. The master orchestration system includes at least one network test module, a module for controlling communications, a database of communication requirements, a decision engine, a database of current communications, a rule database for prioritizing communications, and an administration module. The master orchestration system is suitable for defining which communications between the slave terminals are authorized according to said prioritization rules and for notifying the slave orchestration systems of the slave terminals of their authorization to set up a communication or of the need to interrupt a communication previously set up.

System and method for controlling communications in an ad hoc mobile network

The present invention includes a method for sharing a quantity of resources between several users in a telecommunication network or a computing system starting from a given date. The method includes updating a tree, each node of which represents a time period. The tree contains at least one node representing a time period including the given date. The concatenation of the time periods represented by daughter nodes of a parent node represent the time period represented by the parent node.
