Abstract

To cope with the strict reliability requirements of safety-critical
ADAS applications, the upcoming TSN standard introduces mechanisms
that enable transmission redundancy at any switch or end
node. However, it is up to the designer to decide at which points
and for which messages to activate transmission redundancy. This
significantly increases the design space and requires to trade-off
reliability with other routing-related design objectives like network
load, transmission timing, or the monetary cost of the hardware. As
a remedy, this paper a) presents two different exact approaches to
generate feasible redundant message routings and b) proposes an
extension of the state-of-the-art approach for the multi-objective
routing optimization, enabling the optimizer to directly adjust system
features that are relevant for the design objectives. A case study
with an application from the automotive domain compares the optimization
capabilities of the presented approaches for the routing
generation and demonstrates the significant gain in optimization
power that is achieved with the proposed optimization extension.
