ADCN+(2008-2009)

The AFDX network (Avionics Full Duplex switched Ethernet), as used on the A380, the 400M and the A350, is based on switched Ethernet technology, adapted to avionics standard in order to guarantee the safety and availability of the network for critical avionics systems. One of the major features of the AFDX network is to guarantee the isolation between the different traffic flows due to Virtual Links concept and Traffic policers within the switches. These AFDX switches are expensive and complex components to implement. The objective of this project is to propose alternative network solutions for a backup network (used in case of a major fault of the main AFDX network), based on Ethernet interconnection elements that are simpler than the AFDX switches, and providing deterministic guarantees. The proposed networks are evaluated on a performance analysis perspective, and applied to a typical A380 case.

MARTIAC (2008-2009)

In order to address the increasing complexity of embedded applications, the current solution consists in increasing the number of computers to have more resources and to add new functions. However, this approach leads to an increasing amount of exchanged data and an inherent complexity of system interconnects that make the real time guarantees difficult to assess. Hence, one of the main challenges is to rethink the architecture of embedded computers to improve the performances of new generation avionics applications while respecting certification constraints. The aim of this project is to define and compare some alternative architectures based on multiprocessors for avionics applications.
