Asynchronous traffic handling in time-sensitive in-vehicle network

Abstract

An Ethernet-based in-vehicle network (IVN) gateway with IEEE 802.1 time-sensitive networking (TSN) is advantageous to be used in a time-aware shaper (TAS), as defined in IEEE 802.1Qbv, to safely handle periodic critical traffic, depending on the characteristics of vehicle systems operating in real time. However, the TAS defined in a TSN hampers proper handling of asynchronous traffic in an IVN. This study proposes a method for a time-aware scheduler to handle asynchronous traffic on a time-sensitive IVN.
