An optimized answer toward a Switchless Avionics Communication Network

Actually, ARINC664 is the standard in reference for the Avionics Core Network and particularly the Part7 for Deterministic Network. The current communication architecture already deployed is based on the use of dedicated Ethernet Switch for the management of all data exchanges. These ones are not favorable regarding their SWaP (Size Weight and Power) impact on avionics suite addressing Bizjet or Regional Aircraft. This paper proposes new principles avoiding the systematic implementation of such dedicated communication equipment with a new communication architecture identified as Distributed Network System. This concept is the response towards a Switchless Avionics Communication Network.
