Design and delay analysis of time-triggered AFDX network

  • Received Date: 11 Jun 2012

  • Time-triggered mechanism can enhance the determinacy of avionics full duplex switched ethernet(AFDX), and guarantee the temporal determinacy of time-critical message. Time-triggered AFDX (TTAFDX) was proposed, which is the combination of AFDX and time-triggered mechanism. The architecture of TTAFDX was designed, which includes protocol stack, virtual link, scheduling of end system, scheduling of switch, transparent communication and degradation communication. Delay analysis of TTAFDX was done in both theory and computer simulation, and the result shows that TTAFDX can be a totally deterministic network for time-critical message.
