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.
