Automotive Ethernet provides the new backbone for faster networks to serve autonomous vehicles and advanced driver assistance systems (ADAS). These technologies require higher bandwidth and lower latency. Keysight offers full scale solutions for in-vehicle network standard conformance, functional and performance testing from physical Layer 1 though higher-layer protocols up to Layer 7.

Session 4: Validation and Test
Ensuring Security of Data Communication in an IVN and Comparing the Choice of Encryption Techniques
Connected car security is one of the biggest concerns in the automotive world. With automotive Ethernet, in-vehicle networks are adopting a shared network design. The number of Electronic Control Units (ECU), sensors, and interconnects in cars is growing. ECUs in different car domains will interconnect with Ethernet backbones. Encryption is an established technique in the networking world for securing data communications in a shared network. There are different methods of encryption at different layers of an Ethernet stack. Though the traditional networking world uses encryption techniques, adoption in an automotive environment with time-critical applications and a new automotive physical layer is not proven. Proper adoption requires sophisticated validation methods in the network test cycle. This presentation will focus on the effectiveness of different encryption methods (for example, IPSec or MACsec) in the car network and validation methodologies.

Session 5: Layer 2
When Gates Misbehave for IEEE 802.1Qbv Implementation
IEEE 802.1Qbv provides scheduling across bridges for time-critical application traffic. This ensures predictable and low-latency end-to-end paths for industrial and in-vehicle applications that require precise communication. Accuracy is essential when implementing 802.1Qbv in production devices. Metrics for accuracy measurement include the phase jitter of the opening and closing of time gate queues. A positive phase jitter, in which a gate fails to close within a specified time frame, can allow unwanted bandwidth into the network. For an automotive network, this can cause havoc in terms of the protocol’s data unit (pdu) signal not reaching their destination on time. The applications that typically run inside a car are time-sensitive in nature which needs bounded latency and guaranteed delivery. Requirements of a time sensitive network can only be met by ensuring traffic-shaping paradigms such as time-aware shaper function properly in an automotive network. This presentation will focus on the automotive scenarios where time-sensitive networking paradigms play a major role. We will dive into time-aware shaper implementations, cases where they go wrong, and the impact on an in-vehicle network. This presentation will also cover how to characterize misalignment of time-gated queues in the validation phase and the unique testing challenges.
