Presentation at Automotive Ethernet Congress in Munich, Germany, June 1-2, 2022
Fraunhofer IPMS and MLE present a joint work on how to combine TSN Ethernet and TCP/IP as an ultra-reliable deterministic low-latency transport for tunneling PCIe and other protocols for long-reach. Ethernet has emerged as the connectivity technology of choice. Since real-time networks are particularly necessary for security-critical applications such as ADAS, the emerging IEEE standard “Time Sensitive Networking” becomes an ideal network. Automotive Zone Gateways can be linked together via TSN implementing real-time automotive 10G/25G Ethernet. This creates a need for “tunneling” PCIe over TSN, supporting CPU-to-CPU communication (PCIe NTB) and NVMe storage. Through the use of TSN, data rates of 10 & 25 Gbit / s in the backbone and the high degree of integration of the solution, large amounts of data can be transported and, at the same time, time-critical data traffic with guaranteed latencies can be separated from less time-critical or background data traffic.
