Architecting of Avionics Full Duplex Ethernet (AFDX) Aerospace Communication Network
نویسنده
چکیده
AFDX (Avionics Full Duplex Switched Ethernet) is an avionics data network based on commercial 10/100Mbit switched Ethernet. AFDX uses a special protocol to provide deterministic timing and redundancy management providing secure and reliable communications of critical and non-critical data. AFDX communication protocols have been derived from commercial standards (IEEE802.3 Ethernet MAC addressing, Internet Protocol IP, User Datagram UDP) to achieve the required deterministic behavior for avionics applications. End Systems (or LRU’s) communicate based on Virtual Links (VL’s) with Traffic Shaping by use of Bandwidth Allocation Gaps (BAGs). AFDX Switches incorporate functions for filtering and policing, switching (based on configuration tables), end-system and network monitoring.

The AFDX (Avionics Full DupleX switched Ethernet) which has been standardized as ARINC 664 is based on Ethernet technology. Using full duplex links eliminates the inherent indeterminism of vintage Ethernet due to frames collision, but it shifts in fact the problem to the switch level where various flows enter in competition when using the same output port. Thus main problem is due to the indete...
