Reza Eltejaein from Marvell Technology explained how deterministic Ethernet is displacing special purpose networks in several applications also describing the company’s new Ethernet switches for harsh environments and PHYs targeted to the industrial and critical infrastructure markets. This solution finally brings Time Sensitive Networking (TSN) to reality.
Ethernet is still too expensive for the sensor and other physical device layer. Achieving deterministic Ethernet for critical applications above that layer has been a target for engineering for years. Marvell Technology now offers a solution.
Marvell’s Secure Deterministic Ethernet solution, comprised of Prestera switches and Alaska PHYs, is designed for switch appliances used in often-harsh environments. By enabling the more widespread use of Ethernet in the OT environment, the new solution facilitates the adoption of modern IT tools and security methods in OT networks, enabling a common management and automation approach from the cloud to the OT network edge.
The new solution addresses deterministic networking requirements with a set of Ethernet standards known as time-sensitive networking (TSN). With TSN, virtually any kind of Ethernet traffic can share a network, allowing siloed IT and OT networks to converge, thus reducing costs and facilitating in OT networks the analytics, automation and intelligence that are transforming IT networks.
To better protect these networks, the new Prestera industrial-grade switches with TSN offer industry-first device- and link-level security, in the form of Secure Boot and MACsec.
- Integrated switching, CPU and Ethernet PHY—reduces power and footprint versus separate components.
- Time-Sensitive Networking: 802.1AS, 802.1CB, 802.1Qav, 802.1Qbv, 802.1Qbu, 802.1Qci, 802.1Qat—supports reliable, low-latency Ethernet performance.
- IEC/IEEE 60802 TSN profile for Industrial Automation—enables real-time end-to-end communications with guaranteed reliable performance and data delivery.
- 802.1AE MACsec—provides Layer-2 security for data integrity and confidentiality.
- Secure Boot—allows only trusted software to execute on the system.
- Parallel Redundancy Protocol (PRP) and Highly-available Seamless Redundancy (HSR)—provide no-loss failover in case of failure of any single network element.
- TrackIQ—provides rich telemetry data for use in network analytics and observability tools.
- Ruggedized -40°C to +85°C system operation—enables reliable operation in harsh environments and an expected lifetime of at least 10 years.

Ethernet APL, advanced physical layer, moves closer to reality with this ODVA announcement of the availability of conformance testing for EtherNet/IP network-enabled devices that communicate over the Ethernet-APL physical layer.
Conformance testing verifies the Ethernet-APL physical layer functionality by checking that the different port types properly adhere to the relevant specifications. The EtherNet/IP communication network functionality is also confirmed as a part of this process. Together, both tests ensure maximum interoperability between vendors as well as different types of instruments and infrastructure components.
Ethernet-APL is the new intrinsically safe, two-wire, Single Pair Ethernet (SPE) solution, based on an extension of 10BASE-T1L (IEEE 802.3cg2019), that meets the requirements of the process industries. The advantages of Ethernet-APL include significantly faster communication speeds of up to 10 Mbit/s, hazardous area protection, power to field instrumentation, and long cable runs of up to 1,000 meters (IEC 61158). Ethernet-APL devices adhere to IEC TS 60079-47 (2-Wire Intrinsically Safe Ethernet) in order to ensure “intrinsically safe” ignition protection.

The control and automation market I’ve been in since the late 90s has definitely become a software market. Yes, the main players that remain do still have their legacy controllers, instrumentation, sensors, and networking. The excitement that remains is mainly software and services. Domain expertise within the supplier community becomes increasingly important.
I was coming off a vacation (not planned by me) and couldn’t work out the logistics of making it to Dallas. I kept up with things through press releases and reports from social media guru Jim Cahill. I survived missing presentations by the inimitable CTO Peter Zornio. News came through, anyway.
Announcement summaries follow.
Boundless Automation
This next-generation architecture will empower companies through “boundless automation” to manage, connect and deliver operational technology (OT) and information technology (IT) data seamlessly and easily across the enterprise. Moving data freely and securely across OT and IT domains – from the intelligent field to the edge and cloud – will enable operational and business performance optimization across the enterprise.
It really is all about the data.
Check out Jim Cahill’s report.

A few years ago I thought Time Sensitive Networking (TSN) had potential benefits for industrial networking. This IEEE standard would do the synchronizing that only custom chips do now. As a standard, commercially available chips should be plentiful and inexpensive. Technical snafus ensued. We are still waiting. There are advances.
- Avnu Alliance, the industry forum driving deterministic capabilities into open, standards-based networking, announced expansion of its time sensitive networking (TSN) Test Tool program by opening the test tool ecosystem to new vendors.
