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.
