IEEE Launches Study Group to Explore Distinguished Minimum Latency Traffic in a Converged Traffic Environment
PISCATAWAY, N.J. --(Business Wire)--
IEEE (News - Alert), 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 requirements.
"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 Division.
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
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
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 (http://open-stand.org).
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 (News - Alert): "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, efficiency�and 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
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
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 Hogenm�ller, 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 (News - Alert): "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 control."
