Abstract
Ethernet is a candidate network technology for the future automotive embedded network. Current embedded networks, such as CAN and Flexray, do not provide seamless co-operation with the Internet Protocol (IP) and they do not extend the capacity enough to facilitate innovative distributed applications. Camera Monitor System is an exemplary use case highlighting the need of the network capacity tests before the application enters consumer vehicles. This study focuses on the measurements of \emph{steady state} and \emph{congestion} capacity of a network end-node. We studied two potential measurement methods: Congestion Collapse (CC) test and Variable Packet Size (VPS) probing to estimate the receiver capacity of a network end-node. A comprehensive analysis of the both measurement methods and their requirements for the measurement tools are given. Furthermore, we adapt the CC and the VPS method to take into account automotive requirements, such as flawless frame delivery and feasible measurement process. Finally, we demonstrate two reference tool systems for the both methods and evaluate their drawbacks in real measurement scenarios.
