Optimised packet processing architecture for Ethernet traffic monitoring and analysis in the automotive field

Abstract

Nowadays, modern cars are equipped with computer–controlled features connected by various automotive special communication buses. To preserve consumers' trust in recent automotive electronics, the unsolved problem of system–level test, which goes far beyond testing lone components, should be remedied. In the future generation cars, several innovative applications could profit from the augmented bandwidth Ethernet can offer. In this paper, we present the design and implementation of innovative network analysis of the in–vehicle communication. Indeed, the system functions are accomplished on only one off–the–shelf and cost–effective computer (centralised processing), which permits online and offline analysis. Almost all current challenges, such as flexibility, performance (resource usage) and optimisation are taken into consideration. To validate the performance of our system, named 'CableFish', we perform several tests comparing it to other monitoring and analysis systems.
