AFDX (Avionics Full Duplex Switched Ethernet) standardised as ARINC 664 is a major upgrade for avionics systems. Guarantees on worst case end-to-end communication delays are required for certification purposes. These guarantees are obtained thanks to safe upper bounds computed by Network Calculus and trajectory approaches. Indeed, up to now, the computation of an exact worst case delay is intractable...
In Avionics Switched Ethernet network (AFDX), guarantees on worst-case end-to-end (E2E) communication delays are obtained thanks to safe upper bounds computed by Network Calculus and Trajectory Approaches. Up to now, the computation of an exact worst-case delay is intractable, except for very small configurations. This paper proposes a modified timed automata approach which increases the size of the...
AFDX (Avionics Full Duplex Switched Ethernet) standardized as ARINC 664 is a major upgrade for avionics systems. But guarantees on upper bounds of end-to-end communication delays are required for certification purposes. The objective of this paper is to present an improved modeling approach using timed automata for calculation of exact worst case delays. This approach takes advantage of local scheduling...
