QoS Estimation of In-vehicle Ethernet with CBS and TAS by Multiple Regression Analysis
Honoka Awane, Yoshihiro Ito · 2023
This paper evaluates the QoS of an in-vehicle network with CBS and TAS, one of the QoS controls defined in IEEE 802.1TSN standards, by experiment. The next-generation in-vehicle network uses Ethernet, which can provide high-speed transmission, and adopts IEEE 802.1TSN to support time-sensitive data transmission over Ethernet. In Ethernet-based in-vehicle networks, many devices are integrated, and then various data are transmitted over the network. Consequently, the design of an Ethernet-based in-vehicle network is not easy. Thus, QoS estimation of an Ethernet-based in-vehicle network is required. This study targets QoS estimation by multiple regression analysis for Ethernet-based in-vehicle networks with CBS and TAS, which are major QoS controls among controls of IEEE 802.1TSN. From the results of experiments by simulation, the authors show that QoS can be estimated accurately by the obtained estimation equations.
