A Novel Message Packing Strategy for Time-Sensitive Networking

The rapid development of automobile intelligent driving has led to a gradual increase in data traffic and the number of ECUs, thus raising the requirements for high-bandwidth and low-latency for automotive electrical/electronic (E/E) network architectures. Time-Sensitive Networking (TSN) is used in intelligent automobiles and is served as the backbone network because it can provide real-time communication with high capacity. To achieve the high-bandwidth transmission of data traffic, message packing is one of the prospective strategies. However, the state-of-the-art message packing methods mainly consider the single bus type rather than the hybrid bus type. In this paper, we exploit a heuristic message packing strategy (MA) for real-time traffic based on the multi-domain Electrica/Electronic (E/E) network architecture. Experiment results show that the MA method can significantly reduce bandwidth utilization.
