TSN Ethernet Subsystem Available from CAST Proven at IIC and LNI Plugfests


WOODCLIFF LAKE, NJ, USA -- September 05 2018 -- A Time Sensitive Networking (TSN) subsystem for Automotive and Industrial Ethernet designed by Fraunhofer IPMS and available from semiconductor intellectual property provider CAST, Inc. has successfully undergone functional and interoperability testing at two recent multi-vendor plugfests in Germany: the Industrial Internet Consortium (IIC) TSN Plugfest July 24–27, 2018, in Stuttgart, and the Labs Network Industry 4.0 e.V. (LNI) Plugfest August 22–23, 2018, in Augsburg.

At these plugfests, engineers from Fraunhofer IPMS successfully added their reference design for a TSN end node device to an Ethernet network integrating TSN switches and endpoints from several independent vendors. The resulting TSN testbeds mimic real-world industrial and automotive environments with a diverse mix of real-time signal scheduling and priority challenges that must be satisfactorily managed by the system. The Fraunhofer IPMS design operated successfully, with respect to both its own functionality and in effective cooperation with the rest of each TSN testbed.

Engineers from fifteen firms participate in the LNI Time Sensitive Networking Ethernet Plugfest in Augsburg, Germany August 22, 2018.

“Participating in these plugfests enabled us to rigorously exercise our TSN endpoint design in two different real-world-like environments, each networking our design with switches and end nodes from all the other leading TSN developers,” said Frank Deicke, business unit manager for Wireless Microsystems at Fraunhofer IPMS. “We found that our design performed extremely well and is definitely market-ready, while also gaining insights that will help our customers have even smoother TSN deployment experiences.”

About the Plugfests

Fraunhofer IPMS is a member of the Industrial Internet Consortium (IIC), and participated in the IIC TSN Plugfest that took place July 24–27, 2018, in Stuttgart, Germany. The testing there focused on two of the IEEE TSN standards: IEEE 802.1as Time Synchronization, and IEEE 802.1Qbv Time Aware Traffic Scheduling. Twenty firms contributed TSN designs, significantly enlarging the IIC TSN Testbed, which will serve as the foundation for future testing.

Fraunhofer also participated in the TSN plugfest conducted by Labs Network Industry 4.0 e.V. (LNI) on August 22–23, 2018, in Augsburg, Germany. Fifteen firms integrated their switch and end node designs across an Ethernet network for rigorous functional and interoperability testing.

About TSN and the Ethernet Subsystem

The IEEE TSN Ethernet standards manage challenging networks having a mix of critical and non-critical nodes and have helped Ethernet emerge as the preferred bus for today’s complex industrial and automotive buses. TSN ensures that quality of service requirements are satisfied by prioritizing and scheduling diverse network traffic while also providing ultra-low and deterministically-constrained latency where needed.

Fraunhofer IPMS’ entry to the plugfests is a 1000 Mbps endpoint FPGA board based on a reference design for the TSN_CTRL Ethernet Subsystemalready available from CAST. That Subsystem combines three essential IP cores:

The company believes this is the first commercially-available IP subsystem implementing the latest TSN standards, and has already licensed it to multiple customers.
