Message exchange and generic communications controller structure for redundant avionics communication systems

A message exchange and generic communication controller structure for redundant avionics communication systems, assuming the form of a single component comprising a messages exchanges controller, associated with at least:

• a member forming a messages storage/exchange buffer;
• a member forming connection interfaces for connecting to several messages production/consumption units, one connection interface being associated with one messages production/consumption unit;
• a member forming connection interfaces for connecting to several external messages communication buses, one connection interface being associated with one external messages communication bus;
• wherein the messages exchanges controller is able to:
• recover redundant messages from separate external buses through the corresponding interfaces;
• store those redundant messages in the member forming the messages storage/exchange buffer;
• recover those redundant messages from the member forming the messages storage/exchange buffer;
• and
• process those redundant messages so as to generate a resultant message, to send it to at least one messages consumption unit through the corresponding interface;
• the member forming the storage/exchange buffer is partitioned into distinct elementary structures, each distinct elementary structure storing and/or processing independently one entire redundant messages corresponding to a same resultant message;
• the messages exchanges controller is further able to:
• recover at least one message transmitted by at least one messages production unit through the corresponding interface;
• store that or those transmitted message(s) in the member forming the messages storage/exchange buffer;
• recover that or those transmitted message(s) from the member forming the messages storage/exchange buffer;
• and
• process that or those transmitted message(s) so as to generate a plurality of redundant messages for the or each transmitted message, to send them to separate external buses through the corresponding interfaces, the messages exchanges controller comprising a processing layer able to generate the plurality of redundant messages;
• wherein the messages exchanges controller is further able to:
• recover a plurality of redundant messages generated by the member forming the messages storage/exchange buffer for the or each transmitted message, wherein the member forming the messages storage/exchange buffer comprises a processing layer completely incorporated into the member forming the messages storage/exchange buffer, the processing layer generating the plurality of redundant messages for the or each transmitted message;
• send those redundant messages to distinct external buses through the corresponding interfaces;
• and
• wherein each redundant message comprises a tag making it possible to distinguish it in a group of redundant messages corresponding to a same transmitted message.
