    Abstract: The present invention relates to an avionic communication system that comprises a plurality of switches and a plurality of equipment units.Each equipment unit is capable of generating digital data that are present in the form of a plurality of frames of the first type that are in compliance with a first protocol, or of the second type that are in compliance with a second protocol. Each switch and each receiving equipment unit are configured so as to determine the type of each frame received and, as a function of the determined type, to process this frame in accordance with the corresponding protocol, each frame of the first type being processed on a prioritised basis in relation to each frame of the second type. The first protocol is of the type ARINC 664 P7 and the second protocol is of the type Ethernet with predetermined routing.

    Abstract: An avionics communication gateway including a module for acquiring at least one data message, each message being according to a communication protocol and including a header and a payload including a plurality of successive fields, a module for filtering each acquired message, validating the message if it complies with a set of filter criteria, and blocking it otherwise, and a module for transmitting, to a corresponding recipient, each validated message. The filter module includes a unit for generating a main table for each message, representing a tree of the fields of the payload of the message according to a set of levels related to the communication protocol, and a unit for calculating, for each message, a dictionary table and at least one auxiliary table from among first, second and third auxiliary tables, the filter module using the at least one auxiliary table for filtering the message.
