by the system integrator, and in practice this may mean that the switch shall have a switching capacity that is the sum of all of its physical ports. Since AFDX utilizes the Ethernet protocol at the MAC layer, it is possible to use high performance COTS switches with Layer 2 routing as AFDX switches for testing purposes as a cost-cutting measure. However, some features of a real AFDX switch may be missing, such as traffic policing and redundancy functions. Usage The AFDX bus is used in Airbus A380, Boeing 787, Airbus A400M, Airbus A350, Sukhoi Superjet 100, ATR 42, ATR 72 (-600), AgustaWestland AW101, AgustaWestland AW189, AgustaWestland AW169, Irkut MC-21, Bombardier Global Express, Bombardier CSeries, Learjet 85, Comac ARJ21, Comac C919 and AgustaWestland AW149.
