Traffic Control Optimization for SOME/IP: Evaluating Queuing Disciplines in Vehicular Networks

As automotive systems become more complex, the flexibility and scalability of vehicle software components are required. Scalable service-oriented middleware over IP (SOME/IP) has emerged as a middleware solution for scalability in the automotive industry by facilitating service-oriented communication between devices of various sizes and operating systems. However, one of the major issues with SOME/IP is its limited native support for QoS. In particular, message delays may be inconsistent when the network is overloaded. This poses serious problems for the smooth operation of real-time automotive applications such as advanced driver assistance systems (ADAS), where real-time communication is critical. This paper aims to highlight the specific limitations of the current SOME/IP protocol and improve the QoS of SOME/IP-based communications. The impact of various queuing disciplines on the latency of SOME/IP messages was evaluated. This study aims to systematically apply various queuing disciplines to identify the most effective traffic control method to improve the QoS of SOME/IP-based communications. This evaluation was performed using NXP's S32G3-VNP-RDB3 embedded platform. We implemented the SOME/IP server and client on a Linux-based system and configured QoS management using the already implemented Linux-based software utilities iptables and traffic control (tc). Finally, we discuss the results of this study and future research.
