Time Sensitive Networking to Promote Interoperable Ecosystem

News regarding Time Sensitive Networking continues to flow. The University of New Hampshire InterOperability Laboratory (UNH-IOL), an independent provider of broad-based testing and standards conformance services for the networking industry, announced the launch of three industry-specific time sensitive networking (TSN) consortiums – Automotive Networking, Industrial Networking, and ProAV Networking – designed to provide deterministic performance within standard Ethernet for real-time, mission critical applications. By providing high quality test plans, tools, and test beds for TSN, UNH-IOL allows businesses to improve products and accelerate market readiness.

“Standards-based precise time, guaranteed bandwidth, and guaranteed worst-case latency in a converged Ethernet network is a game-changer to many industries,” said Bob Noseworthy, Chief Engineer, UNH-IOL. “Through UNH-IOL’s industry-specific TSN consortiums, companies can be at the forefront and drive the technology forward by validating their solutions with a full suite of testing services, which will allow applications such as self-driving cars and the Industrial Internet of Things (IIoT) to take off.”

Originally established as a “best effort” network, Ethernet needs additional specific features to deploy mission critical applications. TSN standards enable deterministic real-time communication over Ethernet, allowing solutions to be built to provide extremely precise, predictable timing across the network. By adding features to Ethernet such as time synchronization, ingress policing, seamless redundancy, frame preemption, scheduled traffic, and stream reservation, TSN ensures mission-critical, time sensitive data is not held up on the network, promoting an interoperable ecosystem spanning across many industries. As TSN standards mature, UNH-IOL consortium members are able to support rapid development of conformance and interoperability solutions for emerging standards, validating their silicon and early products by gaining access to test solutions as well as multi-vendor test beds.

A major driving force behind the development of TSN standards is the emerging Automotive Ethernet market. The future connected, autonomous vehicle requires the time sensitivity and predictability in networking that TSN provides to support Advanced Driver Assistance System (ADAS) requirements, infotainment expectations from consumers, and other elements of vehicle electronics. Supporting automotive original equipment manufacturers (OEMs) and manufacturers supplying OEMs enabled with deterministic Ethernet solutions, the TSN Automotive Networking Consortium provides a setting for collaboration and participation in shaping the emerging standards through neutral, third party conformance and interoperability testing.

TSN’s importance is also emerging in industrial automation due to the rise in interest around the IIoT, specifically the mission-critical, time sensitive data that must be transferred and shared within strict bounds of latency and reliability. TSN enhancements for Industrial Ethernet provide standards-based determinism and reliability needed for these applications. The TSN Industrial Networking Consortium brings together stakeholders to realize the benefits of TSN – bandwidth, security, interoperability, and latency and synchronization for IIoT, robotics, assembly plants, and machines, as well as shape the standards and protocols for TSN in the industrial market.

Recent enhancements and certifications in the audio/video market have created a wider choice of compatible products and open technology that brings high-quality AV networking within the reach of any size Professional AV system.  TSN enhancements provide the important timing audio and video systems need. The Pro AV Networking TSN Consortium is a testing ground for the promises of seamless redundancy, low-latency, and synchronization in the professional audio/video market.

UNH-IOL provides the test facility for stakeholders across multiple industries – automotive, industrial, and Pro AV – to drive the emerging, maturing TSN standards.

    I hope they are using the research and open standards that were developed by Yokogawa?
    The V/net IP network adds deterministic/defined bandwidth capabilities within standard Ethernet networks in a redundant manner. This was needed to migrate from the old coax infrastructure.

    It would be a good proven reference for them to work from.

      I’m not sure where you’re going other than to promote Yokogawa’s deterministic Ethernet (rather than Profinet IRT, EtherCat, PowerLink, CIP motion, and the like). TSN is a new IEEE standard under development and close to approval. Rather than only an industrial protocol, this standard is promoted by many organizations including AVNUE Alliance for streaming video and more. This new technology could well replace all these others leading to one unified standard embedded in commercial, off-the-shelf Ethernet chips.
