Abstract: The present invention relates to a method for configuring an avionic network comprising determining sending rules imposing the sending of digital data in the form of frames of a first type or a second type, each frame of the first type being according to the protocol of the ARINC 664 P7 type and each frame of the second type being according to the protocol of the Ethernet type with predetermined routing. The method further comprises determining conveying rules comprising defining a path for each flow of the first type between a sending end system and a receiving end system, determining priority rules comprising defining a priority for each flow of the first type such that the priority of each flow of the second type is lower than the priority of each flow of the first type, and transmitting said rules.

Abstract: 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: the reception of a message at a reception instant, said message comprising at least one time reference determined by a transmitter server, for each message received, the estimation of the current time of the transmitter server on the basis of: the time reference, a value of the internal clock of the current critical device at the current instant and at the reception instant, the minimum value and the maximum value of transmission time of the virtual link between the transmitter server and the current critical device.

Abstract: The present invention relates to a method for verifying a partitioning configuration, between consuming elements (13), of resources (14) of an electronic module (12), each resource (14) having a capacity and being divisible into segments, the method comprising: verifying the compliance with a set of partitioning rules, according to which: the sum of the unitary capacities of the resource segments allocated for each resource (14) is less than the capacity of said resource (14), only the resource segments previously defined can be allocated to distinct consuming elements (13), the use of resource segments by a consuming element (13) is limited to the resource segments allocated to said consuming element (13), the partitioning configuration being considered valid when the set of partitioning rules is respected, exploiting the module (12) with the partitioning configuration.
