Abstract

Ethernet is the dominant network standard for local area networks (LAN). While originally designed for classic office applications, the growing communication demands in real-time systems led to adapting Ethernet for time-critical applications. Today, we can find Ethernet variants everywhere: in industrial applications (EtherCat, Ethernet Powerlink, ProfiNet, Ethernet IP), in aerospace applications (ARINC 664-p7, ASCB/D), in military naval applications (Gigabit Ethernet Data Multiplex System), in consumer audio/video systems (AVB), as well as in datacenters and cloud computing (DCB). All of these Ethernet variants aim to achieve a certain degree of quality of service (QoS) such that end-to-end transmission guarantees can be ensured. In this multitude of Ethernet-variants, TTEthernet introduces the deterministic time-triggered communication paradigm in an Ethernet flavor, which allows the use of standard Ethernet in safety-critical systems and systems with applications of mixed-criticality.
