Some/IP and DoIP: Bringing Service oriented communications to non IP networks and buses
The current automobile is more than just a vehicle—it’s a software-powered system of connected devices on wheels. As we move toward the era of the SDV (software-defined vehicle), the systems inside cars must also grow to communicate with the cloud. Traditionally, most automotive communications have happened through protocols created for restricted data sharing, such as CAN or LIN. However, as elements such as OTA automotive services, real-time navigation, and advanced driver assistance become the norm, the need for service-oriented communication becomes increasingly critical. That’s where Some/IP and DoIP step in. Let’s break down what these two protocols are, how they work, and why they’re essential to future-ready vehicles—especially when adapting to non-IP networks like legacy CAN buses. Understanding Service-Oriented Architecture in Vehicles Before diving into Some/IP and DoIP , it’s helpful to understand why service-oriented communic...
