ABSTRACT:
A data integrity checking system in a frame-switched on-board network, including at least first and second asynchronous transmitter terminals, with the second transmitter terminal being in charge of monitoring the first transmitter terminal, and at least first and second receiving terminals, with the second receiving terminal being in charge of monitoring the first receiving terminal. The system includes a first multicast virtual link connecting the first transmitter terminal to the receiving terminals, a second virtual link connecting the first receiving terminal to the second transmitter terminal, the second virtual link not passing through any of the switches that are common to the branches of the first virtual link, a third virtual link connecting the second transmitter to the first receiving terminal in order to transmit thereto the result of an integrity check on the data received by the first receiving terminal.
