Integration of Predictable and Flexible In-Vehicle Communication using Time-Triggered Ethernet 2006-01-1055
This paper presents a novel communication architecture denoted as time-triggered (TT) Ethernet that integrates real-time and non-real-time traffic into a single communication architecture. TT Ethernet supports applications of different levels of criticality, from simple data acquisition systems, to multimedia systems up to the most demanding fault-tolerant real-time control systems. The event triggered traffic in TT Ethernet is handled in conformance with the existing Ethernet standards of the IEEE. The architecture deploys a TT Ethernet switch, which distinguishes between event-triggered (ET) and time-triggered (TT) Ethernet traffic. Time-triggered traffic is transmitted with a predictable transmission delay, whereas event-triggered traffic is transmitted on a best-effort basis. The paper elaborates on the usage of TT Ethernet for in-vehicle communication in order to integrate different in-vehicle communication subsystems into a single communication architecture.
