Poster: An In-Vehicle Software Defined Network Architecture for Connected and Automated Vehicles

Abstract

Vehicular network architectures are being reviewed and re-designed to meet requirements for increasing data rates and flexibility driven in part by the adoption of Connected and Automated Vehicles (CAV) strategies. A progressive move from traditional bus based networks, such as CAN, to Ethernet-based network architectures is being considered across the automotive industry. In this paper we advocate for an in-vehicle Software-Defined Network architecture and discuss benefits that such a shift in the architectural paradigm will bring by strengthening cyber-security defences and enabling a fail-operational capability through network programmability and provably correct networks.
