`Abstract:
`The time-triggered arcMecture is a distributed architecture fa hi!jl-dependability real-time systems such as avionics systems, engine controls a
`brake-by-wire systems in the autormtive domain. The core element of the a-chitecture is the time-triggered communication protocol TIP. TIP uses a
`time-triggered medum access control strategy, which makes it Wly CCJIT4l0Sable in the time and value domain. TIP usually transmits real-time, state
`data, with small latency and minimal latency jtter. But is also possible to transmit event data over a dedcated event channel. This paper dermnstrates
`how an application can transmit safety-critical real-time data together with non-critical event data and explains the advantages over COIWentiooal event(cid:173)
`triggered communication systems. The autha introduces a generic approach for event-data transmission that makes it possible to layer other protocols
`such as MIL-SID-1553, CAN orTCPnP on top of TIP.

`Introduction
`The Time-Triggered Architecture (TTA) provides a consistent cCJilllUiilg platform for large complex
`applications and safety-relevant systems. TIA has been developed over a period c:l20 yea-s at the
`Ve10a University c:l Technology together wi h industrial partners and other leading research
`institutions. The comer stone c:l TIA is the Time-Triggered Prolocol TIP@ [6], which refers to safety(cid:173)
`en ical, fault-tolerant hig~speed networks.
