a leading provider of network testing, visibility, and security
solutions, partnered with Marvell Technology Group, a
global leader in providing complete silicon solutions,
and NXP Semiconductors, the world leader in secure
connectivity solutions for embedded applications, to deliver
the first public interoperability demonstration of the AVnu
Audio Video Bridging (AVB) profile dedicated for automotive
usage at the Automotive Ethernet Congress held in Munich,
Germany, February 3rd and 4th, 2016.
What is AVB/TSN?
Audio Video Bridging/Time Sensitive Networking (AVB/
TSN) guarantees reliable transmission of audio, video, and
control data over standard Ethernet. AVB/TSN assures not
only a minimum bandwidth, but a maximum guaranteed
latency, which is crucial for real-time media. The technology
enables car makers to use the same Ethernet network for
real-time and non-real-time communications, at much
higher speeds than previous automotive busses. AVB/TSN
allows for more advanced entertainment and Advanced
Driver Assistance Systems (ADAS) features even on lower
end car models.
What was demonstrated at the Automotive Ethernet
Congress?
The demonstration showcased the automotive Ethernet
specific physical layer, IEEE 100BASE-T1 (Ethernet running
at 100Mbps over a single twisted pair), a milestone that
reflects that automotive AVB/TSN is a technology that is
ready for use in production. AVB/TSN allows time-sensitive
application traffic to be carried over Ethernet reliably and
is a common name for the set of technical standards
developed by the Institute of Electrical and Electronics
Engineers (IEEE) Audio Video Bridging Task Group of the
IEEE 802.1 standards committee.
The demonstration included a complex scenario of real
and emulated AVB talkers and listeners from NXP and Ixia
communicating over a network of AVB bridges from Marvell
and NXP. The term ‘talker’ denotes a stream source while
‘listener’ denotes a stream destination.
The benefits of the joint solution were observed on the real
endpoints, as precisely measured by the Ixia AVB tester,
and include:
Verification of synchronization and timely delivery of time-
sensitive streams
Validation of bandwidth, QoS, priority remapping, and
latency guarantees
Checking that both AVB and best effort traffic are handled
appropriately at the same time through the AVB system
Validation of AVB Network boundaries in time-sensitive
networks

Interoperability Demonstration of the AVnu AVB Automotive Profile
•Signing of Memorandum of Understanding at the Hannover
Messe
•Agreement on potential for the joint development of
automation standards for the electronics industry
•Partners intend to cooperate in line integration and
automation concepts
Panasonic and Siemens strive for the common advancement
of digital production for the electronics industry. Against
the backdrop of the Hannover Messe, Hiroyuki Aota,
Director in charge of Factory Solutions Business and
Executive Officer of Panasonic Corporation, and Anton
S. Huber, CEO of the Digital Factory Division at Siemens
AG, signed a Memorandum of Understanding setting out
the intention of the two companies to work more closely
Panasonic and Siemens to cooperate for next-generation
electronic equipment assembly plants
together in the future in the fields of automation concepts
for the electronics industry. The focus lies on standardized
line integration concepts, which the partners plan to
develop not only for individual production lines but also as
overarching integration concepts for all process steps at the
factory level, and as company-wide automation standards
for globally distributed production networks.
Over recent years, Panasonic and Siemens have both
worked independently on pioneering concepts linking
digitalization and automation. In essence, the Smart
Factory offering from Panasonic encompasses automatic
assembly systems and the Manufacturing Execution System
application PanaCIM. With the Digital Enterprise, Siemens
is bringing to the table a portfolio encompassing the
