Abstract: A process for routing virtual links in a frame-switching network including a plurality of source and/or destination terminals of the frames, in which frame switches are connected to one another by physical connections, with each virtual link being defined, for a point-to-point type, by a path through the network between a source terminal and a destination terminal, and, for a multipoint type, by a plurality of paths through the network between a source terminal and a plurality of destination terminals. The process performs the routing of links by minimizing at least one cost function on a set of solutions satisfying at least one predetermined topological constraint.

Abstract: A method for routing virtual links in a frame switching network including a plurality of source terminals and/or destination of the frames, frame switches being connected together through physical connections, each virtual link being defined, for a point-to-point type, by a path through the network between a source terminal and a destination terminal and, for a multipoint type, by a plurality of paths through the network between a source terminal and a plurality of destination terminals. The method carries out routing of the links while observing a segregation constraint with regard to triplets of consecutive switches belonging to the oriented loops, so as to allow verification of determinism of the network.

Abstract: Embodiments of the invention enable the integrity of data processed by a switch to be guaranteed better than 10?9 undetected erroneous frames per flight hour. To do this, rules for disabling ports are included in the switch management program. These rules include a maximum absolute admissible number of erroneous frames, to a maximum relative rate of admissible erroneous frames and a minimum number of erroneous frames constituting a significance threshold. Random errors are detected at the level of each frame due to the insertion of a CRC. Deterministic or data-dependent errors able to deceive systematically the CRC check are made random by means of a frame index.

Abstract: A method and device for monitoring the validity of a parameter calculated by an anemometric unit of an aircraft may employ a first section for taking into account n first data, each dependent on the parameter being monitored and n being greater than or equal to 1. A second section takes into account p second data that each depends on a value obtained from a data source external to the anemometric unit, where P is greater than or equal to 2. A calculator calculates, for each of the second data, a difference between this second datum and a first datum of the same type. A comparator compares the absolute value of each of the calculated differences with a threshold value. A deducing section deduces from the comparisons that the monitored parameter is invalid if the absolute values of two of the various differences are greater than the corresponding threshold values.
