New IEEE 802.3™ study group to examine latency needs and Ethernet-convergence
opportunities in market segments such as industrial automation and automotive

PISCATAWAY, N.J. -- February 13, 2013

IEEE, the world's largest professional organization advancing technology for
humanity, today announced the formation of an IEEE 802.3™ “Standard for
Ethernet” study group to explore the requirements for network latency and
real-time control in industries such as industrial automation and automotive.
The new IEEE 802.3 Distinguished Minimum Latency Traffic in a Converged
Traffic Environment Study Group will look at additional opportunities to
expand the overall Ethernet market and their associated technology

“Companies are eager to efficiently converge all network services—scheduled,
streaming and priority-based, and best-effort traffic—onto the same LAN (local
area network). But for this to occur, particularly in certain market segments
such as industrial automation and automotive, lower end-to-end latency and
real-time control are required in support of scheduled traffic in
time-sensitive LANs,” said Ludwig Winkel, chair of the new IEEE 802.3 study
group and a fieldbus standards manager at Siemens Industry Automation

The purpose of the new IEEE 802.3 study group is to look at the promise of
simultaneous support for undisturbed distinguished real-time control traffic
and best-effort traffic (e.g., audio and video data) on a single Ethernet
network (converged network), maximizing bandwidth usage while retaining the
network's real-time capabilities to support operations in automotive control,
industrial automation and other applications. Individuals interested in this
work are invited to contribute to the new study group, which is scheduled to
meet 17-22 March 2013 at the Caribe Royale in Orlando, Fla., as part of the
IEEE 802 plenary session. Please visit for more information.

“An IEEE 802.3 study group is formed when there is interest in developing a
request to initiate an IEEE 802.3 Ethernet standards-development project,”
said David Law, chair of the IEEE 802.3 Ethernet Working Group and
distinguished engineer with HP Networking. “Once there is evidence of enough
interest in a particular technology area, an IEEE 802.3 study group provides a
forum for global experts to come together in collaboration and develop a
proposal for an IEEE 802.3 Ethernet standards-development project. I look
forward to the work of the new study group exploring distinguished minimum
latency traffic in a converged traffic environment and its insights into
expanding the IEEE 802.3 market.”

Ethernet is celebrating its 40th anniversary this year. Deployment of
technology defined by the IEEE 802.3 standard is already globally pervasive,
driven by the ever-growing needs of local area, access and metropolitan area
networks around the world. Beyond traditional networks, new application areas
such as networking for industrial, automotive and other industries are looking
to expand their reliance on Ethernet in their networks. To better address the
needs of all of these areas, the IEEE 802.3 Ethernet standard is constantly
evolving and expanding. The success of the standard—from its inception through
today—has been its open and transparent development process, which is an
example of the "OpenStand" principles ( These
principles encapsulate a modern paradigm for global, open standards that can
be extended broadly to other technology spaces.

Franz-Josef Goetz, system architect with Siemens AG, Industry Automation
Division: “Industrial automation and control systems today are served by about
a dozen different dedicated solutions, some of which leverage parts of
Ethernet standards already. The new study group addresses the last remaining
requirement in scheduled control traffic that allows for convergence of
control, streaming and data services and scaling to higher bandwidth in
automotive backbone and industrial control networks.”

Mike Hannah, manager, networks, with Rockwell Automation: “Industrial
automation and control systems using standard Ethernet today to achieve
low-latency, high-bandwidth traffic requirements can take full advantage of
these technology advancements. Adopting IEEE 802.3 Ethernet and IEEE 802.1™
bridging techniques for time-sensitive applications would extend the proven
cost, efficiencyand flexibility benefits of convergence across more of our
networking infrastructure.”

Oliver Kleineberg, program manager with Hirschmann, a Belden Brand: “Ethernet
LAN infrastructure has been adopted in industrial automation since early 2000,
and, as the need for converged services and bandwidth requirements grew,
Ethernet became the preferred method for industrial automation networks. This
study group is a great step forward toward meeting the needs of the industrial
automation segment through the IEEE standards process."

Rodney Cummings, senior software engineer with National Instruments: “Both
automotive backbone and industrial automation control networks have common and
native time-sensitive LAN services requirements from the scheduled control
traffic that deals with sensors and actuators. IEEE standards process helped
to bring these common requirements under one study group and promote
collaboration among automotive, industrial and IT professionals."

Markus Jochim with General Motors R&D: “Currently the automotive industry is
focusing on early Ethernet use cases that include diagnostics, infotainment
and camera applications. We anticipate time-critical, Ethernet-based control
applications to play a significant role in the future of automotive electrical
architectures. The support for distinguished minimum latency traffic will
simplify the development of such time-critical control applications.”

Thomas Hogenmüller, team manager with Robert Bosch GmbH: "The ‘distinguished
minimum latency traffic in a converged traffic environment’ is one important
building block for future automotive electronic architectures to enable future
Advanced Driver Assistant Systems. After the introduction of Ethernet in
infotainment and camera applications in automotive we will see more and more
systems will require higher performance than today’s solutions can deliver."

Yong Kim, senior technical director with Broadcom: “The result of this study
group, in combination with projects going on in IEEE 802.1, would provide
support for the convergence of control networks (industrial automation and
automotive) onto mainstream IEEE 802^® Ethernet and bridging technology, and
help to allow future Ethernet networks to converge (scheduled control,
streaming and data), reduce infrastructure costs and simplify management and
