Summary:

The rapid increase of networked electronic control units inairplanes (Line Replaceable Units or Modules, LRUs/LRMs) andautomobiles (ECUs) requires to move from CAN buses to higherperformance buses. In aircraft the number of LRUs exceeded 100 in1990 (B777) and is now 5000 (A380). Today, the number of ECUs insome automobiles also exceeds 100. Aircraft industry developedsolutions based on standard switched Ethernet (AFDX) andstandardized ECUs, called Integrated Modular Avionic units (IMAunits) and common remote data concentrators (cRDCs) that are nowflying in the Airbus A380 and A400M, the Boeing B787, and are beingused in the design of future civil and military aircraft. Duringthe last decade, automotive industry has been pursuing thedevelopment of specialized FlexRay bus solutions for automotivecontrol and specialized MOST bus solutions for comfort electronics.However, some automotive companies are now also looking atEthernet-based solutions.This paper describes some of the steps aircraft industry hasbeen taking to cope with the rapid increase of the number ECUs inaircraft and the use of Ethernet, IMAs and vehicle level executablespecifications for high security applications in aircraft. For anexample of an ABS system it is shown how high security AvionicsFull-Duplex Switched Ethernet (AFDX) buses may be used to replaceCAN, FlexRay, and MOST solutions for automobiles
